Latest Jupiter Images from my Backyard with EdgeHD 11 inch Telescope and a quick 678MC vs 224MC compare (Video)

Here is the summary video from the latest images I acquired in late 2022. Jupiter was much higher this year at near 49 degrees peak. It will be even higher in 2023. In South West PA this makes for better “lucky imaging” in an otherwise difficult region.

2022-10-06 0359 UTC Gain 330 exposure 5.5 Asi224mc 60sec duration best 25% (as in all images below), resized 130% in PS, around altitude 47
2022-10-06 0418 UTC Altitude 48, 60sec duration gain 330 exposure 5.5, perhaps too much processing
2022-09-30 0533 UTC (gain 330, only 60sec here due to using in animation, not 180sec), some moon detail, F20
2022-09-30 0440 UTC (gain 391, altitude 49 degrees 180sec, some good moon detail)
2022-10-06 animation of about 65 frames and 60 sec each frame, 44 to 48 degrees
2022-09-29 Animation, 60 sec each frame

I also had a brief chance to test the ASI678MC camera (not in the video). I found that the resultant images on nearly the same time were not as good as the ASI224MC, so i’ve opted to stick with the ASI224MC for the EdgeHD 11″.

These two examples may not fully show it, but overall the 224 won the war for me. I tried to keep the wavelets similar to get a baseline.

Asi678 180sec 2022-10-24 0323 UTC Gain 287 F19 Alt 48 best 25%
ASI224mc 2022-10-24 0342 UTC gain 287, F19 180sec best 25%

I used the AstroPhysics Advanced Barlow, which had firecap reporting around F20 for Jupiter, even though the backfocus length to sensor was greater than their 90mm, i forget exactly maybe 115mm or so, but likely due to mirror shift.

Generally speaking I would use lower gain on clearer nights and higher gain on other nights to try to increase the amount of frames gathered. 180sec should be the gold standard but that also depends, for instance maybe 60 sec to check focus and do another 60sec after changing focus, or shorter animations.

Overall 2022 was a pretty solid year for images. The other best images I gathered are in the Solar System Gallery and in the YouTube video.
