My first shot with a 224 of Jupiter

[JSeaman]

It has been a couple of years since I have even tried planetary but for £165 I couldn't resist a 224MC. This was my first go with my 12" Newtonian with a Coma Corrector and 2xBarlow all in the chain and it worked OK. I need to get plate solving working with this set up next but I'm happy to have taken a picture at least. This is the best 40% (I started at 5%) of a 3 minute SER video of 0.02 second exposures

That's a bargain for a 224c, great camera.  Nice image but the moons are a funny shape I wonder if that's due t the coma corrector?

Indeed, no need for coma corrector if you are going for planetary.

That small central part of the sensor is well within diffraction limited portion of the field.

No, the coma corrector is only in the loop because I'm trying to minimise what I disturb to switch between my 1600 and the 224, I was hoping it wouldn't interfere and it doesn't seem to. The weird shapes are probably due to poor seeing and not much data. I was only pulling in a bout 2 FPS but I've fettled with the USB settings and dropped to 8 bit and it's now showing 20fps so I'll try again when it's clear
