Good effort Ash for 1st attempt considering no tracking and only 2x Barlow!

It's always exciting to see GRS for the first time isn't it?
Jupiter is now 3 months past opposition and appears smaller by the day.Won't be long before we can't image Jupiter anymore this year.Keep it up you can only improve now. The next thing is tracking by either equatorial mount or EQ platform so you can take much longer video and a 5X Powermate to increase image scale.
Iceman suggested 5fps only when seeing is excellent. Use 10fps otherwise.
If object drift diagonally across FOV then you can take a slightly longer avi therefore more frames to stack.
Practice on the moon's craters after first quarter and get ready for Saturn in Dec.
