Hi chaps,
Been a long day only just now had a chance to sit down.
The camera was my iPhone 8 using Filmic Pro app and attached to a 4.7mm TV Ethos eyepiece on my 28" f4.2 Webster Dobsonian with ArgoNavis and ServoCat tracking. I expanded the ethos image on the iPhone to maximum which is about 5x I expect. Total magnification would be about (2966/4.7)x5 to give 3155 I guess.
It was early in the morning around 4am I left the scope in the backyard overnight Jupiter was directly overhead and Skippy Sky said the seeing was "Yeah baby Yeah!
The tracking was drifting a bit because I'm a lazy sod and close enough is good enough.
