Viewing Report 27th February 2021 – Travel Setup

20:00 – 21:25

Out this evening to find MEV-2 and Intelsat 10-02. Whilst some of the society is providing images to DSTL (MOD) within the UK on the MEV2 satellite, I thought I would have a quick go and capturing. Unfortunately due to the small chip the FoV was not large enough to capture useful images so instead I thought I would capture a movie. Gingergeek joined me by Zoom.

MEV-2 and Intelsat 10-02

So after polar aligning I slewed to Intelsat 10-02 and with a small nudge of the mount the 2 satellites popped into view. The above image shows The Sky X I used to track the satellites on the left and on the right the capture software, firecap, of the individual frames.

I captured a fair amount and will publish a video from it shortly. Gingergeek and I then slewed to the Moon and took a leisurely stroll around the surface. It did to be fair, take us a while to work out the FoV indicator in The Sky X and set it correctly so we could then move to the areas of the Moon we wanted.

Viewing Report 26th February 2021 – Travel Setup

20:57 – 21:53

I pulled out the Mak180 tonight to see if I could image the Moon. After setting up I did not bother with polar alignment due to it really only being the planets which are less picky about tracking. However pointing is another matter.

I have decided I really must get a decent flip mirror. At the moment with the polar alignment not being completed and the chip on the ZWO ASI290MC being so small, I have to take the camera out to then eyeball the planet before putting the camera back in so that its light lands on the chip. Now with the Moon that is not a problem so tonight I did not have to worry.

View from the bridge

Given the short imaging session this evening and the realisation that I had not gotten rid of all the dust from last years dust intrusion I took a single video run of a yet to be identified piece of the Moon.

Raw video footage

I then moved decided to take some video footage of various parts of the Moon to also discover how much dust I had and how much of a problem it was going to be. Also I just like roving around the surface of the Moon.

Raw video of Clavius

I must also buy another ASI290MC as the one I have had its chip cover fall off and I have been unable to remove the dust from Coombe Gibit, so for guiding this is not an issue but for Moon and planets it is. Given I currently take the camera off the Skywatcher Esprit setup where it is used as a guider I might as well have another and then I won’t ever get dust in the new one which I would use on the Mak. As I’ve said before and will say again, Brendan would say it is cheaper to burn Β£50 notes than get into astronomy! How true indeed.

Viewing Report 23rd January 2021 – IMT3

20:20 – 22:11

It is clear! It has been some time, at least for me, when it is clear at a weekend. It is cold. Skippysky.au/europe tells me it is good seeing, the transparency is excellent and the Jet Stream is way South of the UK. The Moon is around 70% and the local temperature is -2 degrees C with a slight frost already. I have come out with my 100mm binoculars to star hope around.

Binos ready and waiting

I had just finished a call with the BASEG society, most whom I had not seen in some time as we are still in lockdown. I came out to a Moonlit garden with a carpet of ice twinkling and crunching as I walked. It is nice to see this new garden at night and get a feel for where I may observe in the future.

I setup the binos in the vegetable patch next to the building works for IMT3b. Not one but twice I stumbled down the trench dug for the cables, so I must be more careful. I then pointed the binos at the Moon and took a look.

afocal Moon

The view was splendid. There is something wonderful about seeing the Moon through binoculars and seeing just how deep you can go. Clavious was crips and easy to spot as was Tyco. I spent some time here and then Luke came out to view. We looked at the Moon first then I moved to M42 which, whilst washed out by the Moon, was still bright enough to see the distinct wings. The trapezium was also very clear indeed.

After a call to Gingergeek, who incidentally was having problems with a disconnected wire in his focuser, I moved onto M45 Pleiades to identify each of the 11 major stars fro Atlas in the West to 18 Tau in the East. Electra, Merope and Alcyone were all rather bright. I then swooped across to Aldebaran before moving across to Mars, the bright planet a small circle in the binos. I then star hopped to M33 to find the surrounding stars without being able to see the galaxy itself.

Mark Radice then called and we chatted about his C11 and the Sinus Iridum mosaic he was imaging tonight whilst sitting in his warm room. We spoke about things to look at and Mark remotely star hoped me to the double cluster, which surprisingly could be seen naked eye, even on this bright Moon night. He then guided me to Uranus which I found in a pattern with 2 other stars making up an isosceles triangle with Uranus being distinctly blue to the bottom right. I was then fairly cold so bid farewell to Mark and headed off indoors to warm up.

Jupiter/Saturn Conjunction Eve – 20th December 2020

GingerGeeks Viewing

The weather forecast suggested that this was the only clear night for some time and the planets were low in the sky. So GeekGirl and I wondered if Jupiter/Saturn were visible from the front of the house to the South-West or if we were going to have to traipse over to the muddy farm fields to view the conjunction.

Luckily for us even though they were less than 10ΒΊ altitude we could see them both between two houses from the front drive. We quickly got some warm gear on and setup the binoculars and the kiddy scope (Sky-Watcher Heritage 150P Dobsonian) on a camping table.

We quickly got Jupiter/Saturn in GeekGirl’s binoculars (Celestron 20×80 SkyMaster). The pairing although not as close as they would be on the 21st still looked nice. The rings of Saturn were discernible and the four Galilean moons were visible in this modest setup and I’m sure the view would be have been better in Dave’s monster binoculars due to the aperature.

Approximate view through 20×80 Binoculars – Credit stellarium.org

In order to get the focus for the planets I used the Heritage 150P on the near half Moon (47%). The views of the craters on the terminator along with the shadows were amazing, we could see the centre peaks of many of the craters.

I wonder what they looked like in Dave’s Sky-Watcher SkyMax 180 Pro ?

Our next-door neighbour popped out and we invited him to view the planets and the Moon. I think he was impressed but everyone reacts differently to the experience.

Once we had both wondered over the Moon, checking out the mountain ranges and the changing shades of grey for the Mares we turned to viewing the conjunction in the 150P using the standard eyepieces (SW Super25 & Super10) that came with the scope.

View of Conjunction through Heritage150P – Credit stellarium.org

We could see all four Galilean moons with Io being placed close to Jupiter’s limb. The division in Saturn rings was visible and GeekGirl could glimpse Titan so she was happy. All in all a pleasant experience, which is rare in the current human malware situation. I finished off the evening with a Brewdog IPA ….. bliss !

Dave Shave-Wall viewing

Start time 3pm – End time 6pm

After deciding that I could not get the conjunction of Saturn and Jupiter at the new house, I spent the best part of 40 minutes packing up the travel scope to travel locally to view the conjunction. I set off to view about 1 mile away across a field with allow horizon. I took my Mak180 without the Barlow and the ZWO290MC on the Paramount MyT with the Berlebach tripod. On arriving at the side of the road on the narrow country lane in North Hampshire, I was just about to setup when I realised not only had I forgot the travel car battery, but also the laptop. After a few expletives and a good old English, “I cannot possibly believe I did this, oh well carry on”, I jumped back on the Landrover and set off back home to retrieve the important parts. On arriving back home I ran up the garden to the shed for the battery, grabbed the laptop and jumped back in the car as time was against me for capturing the pairing before they set below the local horizon about 6pm. It was not 4pm.

I arrived back at the field and quickly set about fitting together the mobile setup for the 2nd time!

Field with a view

This time I settled the tripod and mount up in quick time, slide the Mak180 with its imaging train into the Losmandy Versa plate and connected the Mac. I manually aligned on Jupiter which by this time I could see with my naked eye, synced the scope and started the imaging software. After a few back fourths I found Jupiter, however Saturn was nowhere to be seen. It soon became apparent that my field of view FoV indicator on Sky Safari 4 was not accurate and indeed both planes on this particular day would not fit in! So rather than waste the occasion I shot some view of Jupiter and then slewed to Saturn for the same.

Mak180 ready to slew

I then packed the setup away, but before heading off grabbed the Canon 6D with the 100-300mm lens and grabbed a few exposures. My first attempts were not good, having not used the camera for some time and forgetting how to set the correct exposure. After a while I grabbed a single good frame, over exposed to see the Galilean satellites.

I would attempt another go with the larger FoV Esprit 120 a few nights later.

Viewing Report 28th May 2020 – Travel Setup – Combe Gibbet

19:30 – 03:48

Combe Gibbet

Another visit to Combe Gibbet tonight with another astronomer, GingerGeek. After forcing him to leave the comfort and safety of his own home, where his girlfriend gives him tea, coffee and beer and with the luxury of mains electricity, he joined me at the very dark, very blustery sight near 1,000 ft up in the North Downs of Berkshire, formally Hampshire, they moved the line!

We left at 7:30pm and after the 50min trip arrived at the long road up to and past the Gibbet, which is really not much of a road at all.

Not a road, looking down the bottom part of the track

We drove carefully to the top, both parked our cars and set about setting up for the evening. GingerGeek had his Tak FSQ85 on his CEM 60 iOptron mount whilst I setup my usual array of large 4″ binoculars and at first the Mak 180 on the Paramount MyT. Later I would swap to the Esprit 120ED. To celebrate the outing, little geek had brought some beer πŸ™‚

Beer O’Clock!

The Sun soon started to set, the day trippers hung around to watch the sunset and then were gone. I started looking at the Moon through the Altair Astro binoculars which is just a wonderful sight. A Camera cannot capture the experience of seeing the Moon with its Earthshine and in full as the FoV is 1 degree in the binoculars was a wonderful framing.

Moon through binos taken afocal with iPhone 6sPlus

Next up was Venus before it sets, it is amazing just how bright it still is given its phase. I found in the binoculars eventually as it was hidden behind that cloud band in the distance. I then tried to get it in the Mak180, when a few new things happened. Firstly I could not slew to it as I had yet to polar align, so I had to place the scope in the right place. At the focal length of the Mak180, some 2.7m it is difficult to find something faint behind cloud just by pointing. I eventually gave up. I then noticed my laptop power had diminished by nearly 30% over about 20-25 minutes, this was due to Firecapture just hogging the USB bus capturing 100’s fps. So I was going to start the night short on juice! So I turned Firecapture off whilst I went to find Mercury in the binoculars.

Venus through 4″ binos taken afocal with iPhone 6sPlus

Mercury was a challenge, so much so I could not find it, I put that down to that not well placed cloud band. Meanwhile I pointed the Mak180 at the Moon to have a look, but by the time I had finished I the laptop was done to 53% !!!! Not so good.

So it was time to chat to GingerGeek (GG) before I put the Esprit 120 on the mount. GG was having lots of problems setting up. Firstly he had swapped the rings on the mount for the Tak that day and was struggling to balance the scope. It was so bad the scope kept dropping nose first then camera first and then either way depending on its orientation. Eventually, after much cursing, actually a lot of cursing, GG settled for the imbalance and continued to setup, unfortunately not before he knocked his beer over in his boot of the car ? fortunately I did not laugh too much ??

I went back to my setup, placed the Esprit on the mount and then set about getting focus with Ezcap, the software that comes with the ZWO camera. I do find the software very straight forwards and does what it says on the tin as it were. I then slewed to one of the open clusters I wanted to image and realised it resided in the North and that the twilight was still very much apparent so not suitable for imaging. Instead I settled for M51 high up as to the West was the Moon.

M51 300s Image uncalibrated

It is a lovely image at 5 minutes, I could see instantly at least 4 other galaxies and the colour of the main Messier galaxy was very pleasing. I look forward to processing the resulting subs. I set the timer for 1 hour (12x300secs) and went back off for veggie soup, cheese rolls, brownies and coffee that GG had kindly brought along.

crop of uncalibrated 300s M51

GG at this point was having issues focusing for his 5 minutes shot of the Pelican in Ha, he had made some other changes to the software before heading up the hill too which was confounding him. After some more time he finally had focus and started to image. However whilst a few of the images were okay, the resulting imbalance and gusts of wind made it difficult to keep pin sharp images. It should also be notes at this point that GG and I were running from the same car battery, although GG was only running the camera from it, the mount was running from his Lithium battery.

Stunning Pelican Nebula – 300s Ha uncalibrated

At just before 1am the inverter connected to the spare car battery turned off due to loading and power. Everything stopped for both of us ??? however GGs mount kept running due to the Lithium battery. I closed down my setup and allowed GG to reset his camera and reconnect, he then went on to start imaging, however the resulting image had moved significantly and GG decided to give up. So we spend the next 40 minutes packing up. Whilst this was going on we looked at Saturn and Jupiter through the binoculars which was a wonderful sight. Now for the 50 minute drive home to unload the car just before dawn, although by 2am it was clearly getting lighter.

Guiding graph on Esprit 120 Paramount MyT last night, all over the place with wind

The SQM for the site last night was 20.91 although the Moon was very bright. The site is also very dusty, and my laptop was covered in the morning. Another incident was that I inadvertently unscrewed the cover from the guider as I transferred from one scope to another and the glass cover fell out, I now have dust and dirt on the sensor to clean. It is not a great design by ZWO for the ASI290MC as it really needs a locking grub screw to top that happening or a reverse thread.

Herbig-Haro object at the end of the long feature can just be seen.

GGs image has set us on a little project to image the HH 555 bipolar jet at the end of the major turn of gas in the Pelican Nebula. We will attempt over the next few nights to get an image from both the Esprit 120 ED Pro from the IMT3 dome in Ha and also from the OS 12″ to see what it looks like compared to the Tak FSQ85. Another good social distancing astronomy session ? goodnight.

Viewing Report 25th May 2020 – Travel Setup

19:00 – 05:00

Alan and I

So back off to Combe Gibbet again tonight for hopefully a full night until dawn and with a coat. I met with my friend Alan for once again some social distancing astronomy. Again Alan had a much better 4×4 car to get up to the gibbet than my little electric Nissan Leaf, however once again I managed to make it there.

Sunsetting with Esprit 120 and Alan in his chair

After setting up, it quickly became apparent that I forgot the guide camera as it was still attached to the Mak180 that I thought I would leave at home tonight ?

Quick look and focus on the Moon

So despite the slight setback I polar aligned on the uneven ground and managed to get the scope pointing in the right direction. It took me a while to work out why it was not pointing at the objects when slewing with a perfect alignment, then I realised I had the location set incorrectly. A quick look at my GPS on my phone and I input the coordinates into The SkyX and the target was nearly spot on. I adjusted, performed a sync and then was able to slew continuously thought the night with the object in the FoV.

As I was challenged with no guider I could only take 2 minute images and if in the West low down then 1min. So I stetted for those 2 exposures along with 30 seconds for one particular object.

Below are the lost of targets I went after and imaged. I tried to get 15-20 minutes in total for each. We had some early night high cloud, the wind had again dyed down after sunset and although cold, we were both wrapped up warm, although later in the night Alan became cold so wrapped himself up in the dog blanket from the car ?

First up was M44 Beehive Open Cluster, which filled the view nicely so I took 20 x 60 seconds, careful not to saturate the stars. The QHY168C camera was set to Gain 7 and Offset 30 with a temperature of -20℃.

M44 60s

I then tried SH2-129 emission nebula but no luck, it was not registering at all at such short an exposure. I had a similar issue with SH2-155 Cave nebula. Both of these I will try again when I have my guider.

I then slewed to NGC 6888 Crescent nebulaΒ and took 20 subs of 120 seconds.

NGC 6888 Crescent 120s

Next tried to image Trio in Leo M65, M66 and the NGC but I realised I had already imaged, although not processed and the image trailed at 1 minute due to its westerly location. So instead I headed for NGC 7243, a lovely Open Cluster in Lacerta and part of the Herschel 400 at 60 second exposure.

NGC 7243

Next I looked at the double cluster in Perseus and decided to quickly take a few images with the Esprit 120 ED even though it was not on my original target list. Due to its bright stars I took 40 x 30 seconds.

Doublers Cluster in Perseus

Now it was time to grab an image of Comet c/2017 T2 PANSTARRS which was located near a galaxy called the Coddington Nebula. I purposely got the comet at the very edge of the frame to get the galaxy in, although I noticed the tail was pointing in the opposite direction than shown on Sky Safari.

Comet C/2017 T2 PANSTARRS and Coddington Nebula

The night wass really dark, even though it is not true astronomical darkness, the location really helps. The image quality is also much better. I slewed to NGC 7000 the North American nebula that Alan was also imaging. Again 60 seconds was probably not long enough so I need to come back to this object when I get my guide camera fitted.

NGC 7000 North American Nebula 60s

Finally just as dawn was approaching and the light was clearly increasing, I took a few images of Comet C/2020 F8 SWAN to see if I could see it. Was was apparent was it was super faint even at 60 seconds !

Comet C/2020 F8 SWAN

So as dawn approached, Alan and I took flats, darks and flat darks.

During the night we viewed through the 4″ binoculars the Moon, Venus, Mercury, Double cluster, M39 Open cluster, M57 Ring Nebula, Alberio, M56 Globular Cluster, Saturn and Jupiter. Unfortunately I packed up the binoculars before I remembered Mars was up ! So packed up the car, ands drove very tired 50 minutes home.

Viewing Report 24th May 2020 – Travel Setup

19:00 – 01:12

Tonight I traveled 50mins and 26 miles to Combe Gibbet, a high point for us in the South of England called the North Downs in Berkshire, which at 940ft above sea level places it in the wind, so it is cold but affords a distance from many towns, so it is dark. The is indeed a Gibbet at the top if one should want to take a hanged man or woman and display them for all the surrounding villages to see ? very barbaric, but part of our history.

The car was packed with various astronomy gear, the Mak180 for Lunar and planets.

Mak180

The Esprit 120 ED Pro.

Esprit 120 ED Pro

And of course the Altair Astro 4″ binoculars with my Paramount MyT mount.

Altair 4″ Binos and Paramount MyT

I met a a social distance my friend Lawrence who was in a much better car than myself more suitable for the off-road terrain of getting to and just past the gibbet. Lawrence brought his trusty binoculars and his deck chair. Meanwhile I setup the 4″ Altair binoculars, the Mak180 OTA on the Paramount MyT and my Canon 6D on a tripod.

All set for tonight
Sun setting

As the Sun set from this location we spied Venus first and took a look through the binos.

Moon, Mercury and Venus

I captured some frames in the Mak180 with the ZWO 294MC camera. We then moved to the sliver of a Moon 2.8% illuminated and 1.6 days old. I placed the Mak180 on this for a few frames also. Lastly we moved the binos to Mercury, which is unbelievably small. Very faint in the twilight sky and surprisingly faint in the binos. I once again slewed the Mak180 and captured some 4GB files.

Lawrence looking at the Moon

We then went a hunting for comet C/2020 F8 SWAN but it did not appear in the star field where it should be despite being able to see Mag 8.9 star. The comet was purportedly magnitude 5.8 but this was not the case. I checked my ephemeris on both SkySafari and The SkyX and I wass definetly in the right part of the sky and confirmed the star paterns from my star hoping, but alas no comet.

Lawrence looking at Mercury

So although the wind was now dying down both Lawrence and I were cold so at just gone midnight we packed up and set off home. I must remover by coat tomorrow!

Addendum, I had read an article the following day that the comet may have broken up but I cannot yet confirm this.

Throughout this time I processed some Lunar images on the Windows laptop with AutoStakkert from the previous few nights of imaging through the Mak 180. I have noticed you cannot open anything larger than 4GB file size !!

Gassendi crater

@1:52am TPoint finished

@2:09 GingerGeek took over to look at focuser positions and backlash and autofocus on the Takahashi FSQ102.

Autofocus

Then we started to image M53 on the Tak for RGB data to add to the Luminance data we already have from GingerGeek’s data on the Esprit 120ED.

M53 Frame and Focus test

Tomorrow I will need to look at the TPoint model to refine it!

Addendum ……

So I took a look at the TPoint model and could not get it below 109 inner circle and 200 outer circle without removing a lot of points. So I posted question on the Bisque Sky X forum.

They came back and stated there is something loose in my imaging train or the mount. There is nothing wrong with my imaging train so instead I performed adjustments on the worm gear as they suggested. I will now need to re-TPoint to see if this makes a difference.

Bob’s viewing report: 6th April 2020 – More Comet chasing

Chineham Scouts say ‘Thank you’ on Zoom session whilst viewing the Moon

After helping with a BAS Outreach event using Zoom to share images from IMT3 of Venus and the Moon with 1st Chineham Cub Scouts (to help them acheive their Astronomy Badge) I joined Dave and GingerGeek for a joint observing session chasing Comet C/2019 Y4 (ATLAS) with Dave’s 12″ OS.

Comet C/2019 Y4 ATLAS through 12″

I continued to observe after both Dave and GingerGeek called it a night, my aim was to get some data from the Esprit 120 of C/2019 Y4 (ATLAS) as the previous nights run had been terminated when the clouds rolled in.

Quick 10min Exposure through Esprit 120 Comet C/2019 Y4 ATLAS

I set up another Profile in SGPro for GingerGeeks Esprit 120, adding his Lodestar Guider. C/2019 Y4 (ATLAS) was too far from the equator for the Calibration of the guider in PHD2, so I slewed to Bogardus in Auriga, cleared the calibration data for the Lodestar and re-calibrated it. I was then able to get two 10 minute guided exposures with the mount tracking at Sidereal rate before the comet disappeared from view below the roof line of a neighbouring house.

Comet C/2017 T2 PANSTARRS 10min Exposure Esprit 120

Having lost Comet Atlas for the night, I checked Heavens-Above for other candidates and found C/2019 Y1 (ATLAS) was about to drop below the horizon, but C/2017 T2 PANSTARRS was reasonably well placed, albeit a bit low, and only a short slew from where the telescope was already pointing. After slewing to PANSTARRS and a 5arcminute JOG Up, Left, Down, Right and Down I had it reasonably centred in the FoV. The first 10 minute exposure had star trails, thought I was guiding but found the Mount was still tracking at ‘Custom rates’. The next 10 minute exposure also had stars trailing even though the PHD2 Graph looked fine. I then discovered that with the SGPro profile changes I’d made I hadn’t connected to the ASCOM Telescope Driver for TheSky. The next 10 minute exposure was not much better as by now I’m imaging down in the weeds πŸ™ . Time to find a new target … as it is up and really bright drowning out most objects I slewed to the Moon for a few final shots of the evening.

Viewing Report 4th April 2020 – IMT3 & Travel Setup Mak 180

Viewing time period – 18:42 – 04:21

Hoping to perform a TPoint run tonight, along with gathering some frames on M53 through all 3 scopes (along with Darks and Flats for the Esprit), as we only got some frames through the Tak yesterday. I also hope to try out the Mak 180 Sky-Watcher on the portable mount at the same time from the garden. I will also join the BAS Zoom meeting with all the rest of the gang on as we go through the night, which we have been doing for the past 11 days due to this unprecedented lockdown of society globally due to the Coronavirus, Covid-19 SARS-Coronavirus2 outbreak.

So progressed well tonight, spent the whole night on Zoom with the other astronomers so good company. Managed to image the following Lunar 100 objects, L13 – L30 – L42 – L53 – L59 – L65 – L68 as well as Venus which was at a phase of 44.75%.

@23:53 finished imaging with the Mak 180

Unfortunately M35 has now set and Bob is still imaging the Moon so I will have to grab M35 tomorrow early if it is clear……

I saw big problems with calibration with PHD2 which need to be looked at on the Tak.

@4:21am went to bed whilst the IMT3 was taking Darks

Things to still resolve

  1. Check out why WSX is loosing connection and shutting the dome
  2. Clean filters for the 12″ to get rid of doughnuts
  3. Clean sensor for QHY168C

Viewing Report 5th/6th October 2019 – Travel Scope – Tenerife

Viewing time period – 21:20 – 01:11

Moon and Saturn

This evening started with the Moon high in the sky and waxing its way to half. Next to it Saturn sat, close in fact, so close I pointed the scope at it, around 22:30 and both the Moon and Saturn fit in the same field of view πŸ™‚

So I took a few exposures, worried that either the Moon would be overexposed or Saturn underexposed. I settled on 0.001s and took a bunch of shots. Below is my setup by the light of my rather bright head torch, turned on only for this photo I might add.

Esprit 120 and MyT

Next it was back to trying to resolve the guiding issues that had troubled me the night before. The good news was Tom from the Software Bisque website (not the Tom Bisque, another Tom) had come back with a few suggestions and questions that made me think. I had a good set of guide stars to choose from.

Hw many guide stars!

The autoguide Setup window is where I would spend most of my time I was sure, changing parameters.

Guider settings

I recalibrated the mount, this time using 100arcsec as the parameter. The previous calibration run produced a rather short cross.

Poor calibration ?

This gave me a better ‘cross’ and I think should improve the guiding, although I am still skeptical about just how quick it calibrates, some 4-5 seconds.

Better calibration

Back to guiding the mount was still all over the place, I am convinced it is overcorrecting, on the basis if I don’t guide I get better stars up to 45s or so. I added in a much longer settle period and this seemed to help, but still the graph is a long way from the sort of guiding I was getting before they updated the software.

Poor guiding

The wind was a bit gusty tonight as last night and for sure this was not helping, you can tell from a few exposures it was wind related jumps and drifting

I sat back after a while of changing different settings feeling that it was not improving, so I took a whole bunch of images, only 90s of the Sharpless object Trevor had mentioned, SH2-101 which is called the Tulip nebula. Trevor had produced a lovely image from his 14″ in the UK so I thought I would have a quick go, knowing most of the frames would be lost.

Final set of guider settings

So by 00:30 I decided to start to pack up, the wind had picked up, I was cold, the guiding was still a problem, so by just gone 1am I was heading down the mountain, some 1 hour and 20min drive! The final view from the bridge as it were was this.

View from TSX

The next day I processed the data for the Sharpless object and it was ok, given the short amount of data. One for the 12″ I think.

SH2-101 Tulip Nebula

Meanwhile I processed a single image of the Moon and Saturn and was pleased with the result as seen above. Here is a version with Saturn as an insert.
