This was my very first attempt at planetary imaging with my SCT6. I’ve been doing EAA work for a few years now, but mostly DSOs through the use of a Hyperstar. Last night I removed the Hyperstar from the rig and made my first attempts at imaging at the native 1500mm focal length.
This was a 5 minute video processed with lucky sampling.
I think that’s your mom, for scale
Okay, that’s funny, and I refuse to downvote, but I also am interested in an answer!
Using Stellarium, I can see that Io transited Jupiter last night. It doesn’t quite match OPs photo, but that could be due to being at a different location on earth from where stellarium was simulating, or stellarium is just wrong.
