Jupiter 20 sept 2022

 I wanted to try higher sampling to see if the quality could be made better. So I pulled out my 4x Powermate. With 2x binning I was hoping to max out the resolution of my 200mm Klevtsov-Cass. I set Firecapture to record 240 videos of 1000 images over 4 hours. But, of course, after months of nothing, Windows decided this was a great night to update. So while I was sound asleep, and only about 90 minutes after I started the timelapse, Windows restarted and the rest of the night was a waste. But at least I got 82 images after processing. And I did get better resolution. Or at least, it seems so. I am still not pleased with my processing skills, but I am hoping that it will improve as time goes by. The moon Ganymede popped up casting it's shadow at the end of the timelapse. An extra bonus.

Jupiter rolling

I got up early wednesday morning at 1.30 and went out to the telescope that was already set up on my balcony. I aimed it at Jupiter. After some focusing and calibration, I started recording a timelapse. I wasn't sure how it would fare. I have shot Jupiter before, but not with this telescope. And not from Norway. After some processing, I am now happy with the result. I see that I still have things to learn about getting the most out of the images. But that is something I love about astrophotography; there's always new stuff to learn. This is a 2 hour timelapse with one image per minute. Sped up so the whole sequence takes 10 seconds. The two moons visible are Europa on the left and Ganymede on the right. Europa cast a shadow on Jupiter at the end of the timelapse. An extra bonus!
