A short trip out tonight and only with the binoculars. I wanted to start my journey through Orion star hopping using the Night Sky Obervers Guide as my bible.
With the tagging of objects as follows I setup the binos and went about looking up
Sp – Showpiece
Bs – Binocular Sky
Bo – Binocular Objects
34 Delta Ori (Bo) – The first object for tonight. Given the time I started and taking Orion’s belt as a reference, the middle star called Alnilam or 46 Epsilon Orionis was at an altitude of +09 vs if I had gone out earlier at say 7pm of +37 so this was a challenge before I started.

I did however see 34 Delta Ori (Mintaka) at Mag 2.2 and instantly knew it was right as I could see its double star companion around 1’oclock shining at Mag 6.8. It was a lovely sight seeing this visually tiny companion next to this larger and brighter star. Was very pleased I had started observing visually again.

41 Theta Ori (Bo) – Not seen as set
42 Theta Ori (Bo) – Not seen as set
43 Theta Ori (Bo) – Not seen as set
41 Iota Ori (Sp) – Not seen as set
48 Sigma Ori (Bs) – Another lovely little double star, just South West of the first of the belt stars from the left, Alnitak, 48 Sigma Orionis is a Mag 3.8 star and I could clearly make out the Mag 6.7 at around 10 o’clock.

B 35 – Not seen as expected due to lack of aperture
Basel 11B – This is a really tiny open cluster of stars, I knew it was there as I star hopped from Mu Gemini that I could see clearly at Mag 2.9. I could see Chi1 Orionis and Chi2 Orionis that form the upper stars in Orion’s club but it was easier to star hop from Mu Gem.
Finder chart for just North of Orion
Basel 11B sits just North West of the club and reportedly has 12 stars, I could only see it with averted vision due to the aperture of the 100mm binos, however I would say 3-4 were visible, given they are Mag 10+ so pretty faint for this instrument.
Basel 11B
Berkeley 21 – I was really not sure if I could see this, even with averted vision. The cluster is about Mag 11 so right on the limit of my instrument. I kept going back and forth, I was in the right area as it is fairly next door to Basel 11B. I jiggled the binos about but I could not be certain. I will have another go when Orion is higher earlier in the night.

So that was it for me, Orion was setting so it was time for bed.ß
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.
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 10º 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.

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.

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 !

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.
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.

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

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 tonightSun 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.
