I had a new astro computer I built from scrap to test this night and also it was a test of the AT60ED and QHY294c with the ultra-mini guider and IMX224 camera on the new SkyWatcher GTi mount.  The above equipment was 7.5 lbs, well within the 11 lb limit of the GTi mount and I had great guiding for the most part.

I bagged the four objects above on this night.  A Baader UHC-S L-Booster filter was used to block the horrendous LP, which worked pretty well with the QHY294c.

The three versions of the Veil Complex were, for frame 1, essentially the 60 frames stacked and processed normally.  Then, that result was put through Starnet++, which removes all the stars and leaves just the nebula, which is frame 2.   I boosted that to bring out more nebula and then recombined it with the original to obtain an enhanced version in frame 3.
