Just watched the ISS go over, first time for GingerGeek. Videoed it using the iPhone 8 and it came out great. Also have the lovely noise of an owl in the background.

Started Tpoint at 11pm. Used 30 second exposures and image scale of 0.33 arc/pix. I am performing a 212 point Tpoint model.

Well TPoint model complete, of course I forgot to initially do around 25 TPoints, adjust the polar alignment which is our in Azimuth by 2.1 arcmins and then rerun.

Meanwhile before we finished I ran one of GingerGeeks M13 images through PI as a single frame from his new camera.

Another long pause between observations, after what seems like 3-4 weeks if not 1-2 months of storms, gales force winds and rain. However, tonight Bob came over and now that I have the new rotator installed with the new adapters I could use the 12″.
Ready for darkness
We setup under clear, warm and light skies. For the first time we put a couple of chairs and table down by the IMT3b. Bob helped setup the 6″ dob and the 100mm binos. We opened the dome and awaited darkness.
100mm Binos
I wanted to make sure that the rotator worked well, that the Field of View, FoV, worked within TSX and that I setup a small amount of Points on the scope. We also decided to see if we could visually see the Intellsat satellites and that I could track on them with the 12″.
Whilst waiting for darkness, Bob found what looked like a planet rising in the East, however it turned out to be Vega. We noticed in the corner of the IMT area by the IMT shed that you could see not only Polaris, now the Sycamore had been removed, but also low in the East and thus Vega at +11° altitude.
Bob then spotted Polaris first! Amazing! I normally find stars first, especially Polaris. However given Bob was in my garden and unfamiliar with the his bearings it was astounding he found Polaris so quickly. Well done keen eyed Bob 🙂
Soon darkness fell and we pointed the binos and scopes towards Intelsat. It became apparent quickly that we were not going to be able to eyeball it due to not having a good enough understanding of the surrounding star field. Meanwhile on the 12″ we slewed and quickly found the satellites. We then use the rotator to move the FoV so that we could fit 4 satellites on the chip which was pretty cool.
Intelsat and Thor satellites
We then star hopped to M5 with the bins, then with the 6″ and finally with the 12″. The view through he 100mm binos was of course fantastic, fair superior to the 6″ dob. The image through the 12″ showed a dense star field.
I then set about collecting a half dozen Tpoints just to make sure that objects we in the FoV, however the first slew proved the polar alignment was good enough to do this. I produced a small TPoint model and stuck to that for now. I will need to go out later this week and perform a much longer automated TPoint. For that I need to fix the dome this is currently jamming.
We then sorted the rotator out, making sure the angle and FoV represented in TSX was correct. After changing the x and y values for the FoV indicator it worked perfectly.
About midnight we saw the best fireball ever cross in towards South East just below Arcturus. It was very orange and stunning.
After then slewing the 12″ to M81 to make sure the rotator reflected what we actually wanted to see, Bob and I called it a night. The Moon was due to rise shortly.
A good night for us and welcome after the rain and a harsh Covid-19 lockdown.
