I happened on a fantastic saturnian moon alignment last week viewing on January 18. I could only make out four strung out in a perfect line with the planet's equator, but after checking Starry Night to identify which was which I found that Mimas and Enceladus were there too. I wish I had imaged at a short focal length to record it as you have done. The seeing wasn't too bad, but I had a very difficult time with the wind and low transparency. Completed an image this morning:

Thus far this is the only data I've recorded this apparition worth wrestling with - and it is almost opposition already!

Well that's much better than I've achieved. This last 6 months has pretty much sucked turbulence wise.

Just out of curiosity, how many frames of video are you recording per stream and how many are you using for stacking? I was shooting about 2000 frames and then letting Astro IIDC pick the top 100 frames for stacking. Even doing it manually, I don't disagree with what Astro IIDC picks (i can have it dump out the frames manually it selected).

Thanks in advance..
