  1. I had decent seeing, but rubbish and variable transparency on 30 October 2022. It's the first outing after the end of daylight savings, so good to be able to start capturing at a more sociable time, even though my body clock hadn't reset yet. The 3 images are approximately one hour apart. Each image comprises best 6000 frames from 3 SERS (so 18000 frame per image). All captured with my ASI462MC through the C14 with ADC. Captured in FireCapture and processed in AS3!, Registax, WinJupos and Affinity Photo.

    The sky around Jupiter had seriously detoriated by the time of the last run, so I gave up and waited for Mars to gain altitude, with the results from that session already posted.

    Thanks for looking.

  2. Both are excellent images Stuart. Only just seeing this thread and I also prefer the 2nd image (didn't see your original 1st as you've updated it). I guessed the 2nd was with the ADC due to the larger image size, guessing based on increased magnification with the sensor being further back from the x3 tv.

    Hi Geof,

    Many thanks for your reply and your example image taken under that jet stream activity.  I, like Pete above, would generally give it a miss if the conditions were predicted to be bad unless it had been many weeks since my last observation when I would give it a try.  If I have been fortunate to have been out several times in a week I would likely take a "bad jet stream" night as a evening off. 

    You do realise however I may not now be able to relax when conditions are predicted to be bad based on your image just in case I am missing something! :O)   

    Yes, it does my head in when I decide not to bother when the Jetstream is active. The image that I got that night is my best from Jupiter's apparition this year, though I was somewhat late to the party due to other commitments. Having an observatory, does make it much easier for me to have a quick look just in case.....🤔

    Beautiful images,. You must have been up early / stayed up late.

    Really enjoyed this and looking forward to seeing more as we approach opposition (subject to better weather of course!). 

    Thanks Mark. It was a long session starting with Jupiter around 7:30pm (I'm currently working on that data), then moved over to Mars once it gained a decent altitude. Seeing was mostly fair to good, but the variable transparancy made capture very tricky, especially with Jupiter at a lower elevation. Mars definetly got easier once it got up towards and beyond 50°, but then the fog piled in about an hour before it was due to transit, so that was game over. It is good to be back on GMT (UT), as everything is now happening an hour earlier......:thumbright:, just need my body clock to adjust.....🙄.

  5. I finished processing the Mars data, so here is a Mars rotation GIFF covering approximately 2h 20m elapsed time. There are eight separtae SER runs included, with some significant gaps between them early on, plus the usual hard to tame Mars edge rind in the earlier images, hence the rather jerky rotation.

    In particular, I think the GIFF helps highlight the three Tharsis Montes volcanoes, as they disappeared into Mars night.
