Thanks Martin,
I have been getting 5min subs which are great so I will be able to do that. Have just received a ZWO EAF so I will be able to get many hours on the horsehead without needing to get up and refocus.
Should I dither every frame? I have found that dithering every 3 frames works pretty well. I haven't had any walking noise at all and my darks seem to subtract any hot pixels extremely well.
I have been looking into a reducer and am thinking of the Bintel 0.8 reducer for short telescopes but am doubtful of the quality. I also have a flattener already installed. If I got a reducer, would I use both the flattener and reducer at the same time or would I only be able to use one of them at the one time? 0.8 reducer would get me down to 480mm focal length and f/5.3 so a decent reduction in f ratio.
Thanks
Lachlan
