About this image

Raw files, collected over a period of 20 minutes) edited with Veedub, debayered with PIPP, quality graded and 10% of best frames stacked with AutoStakkert 3. Resultant stacked image files processed (including wavelets) using AstroSurface freeware, then combined with Winjupos and re-touched with AstroSurface and finally Topaz Gigapixel. Had to find new wavelet processing software as finally RegiStax 6 seems not to work properly on my computer, despite re-installing. Would certainly recommend AstroSurface.

Nice Mike. You on an equatorial platform for tracking?

Thanks Martin. In fact no, my telescope is on a Alt/Az mount, but it does guide quite well with ArgoNavis and ServoCAT; just a few tweaks of the hand controller, if any needed at all, to keep the planet in the small frame of the ASI224MC sensor during the short video acquisition time. I only bother with field rotation when I use it for deep sky imaging, but even then I usually employ SharpCap's Live Stacking function which takes care of that (at the expense of some image cropping). I see that I mistakenly said I used a 2x barlow, in fact it was 3x.
