Wasn't going to post this until I had time to shoot proper flats for 2x2 RGB bins. I'm still having trouble dimming my light box sufficiently for the QHY9, and haven't had time to address the issue - so pardon the vignetting.
Last Thursday I finally had everything to shoot RGB, albeit still struggling to get enough backfocus and 55mm distance for MPCC - had to take the 12mm window off the camera in the end. Shot 30sec images of ETA through intermittent cloud, but then had a go at 5mins subs before calling it quits after realising it might be another 2 weeks before decent weather (and I didn't miss the mark at all with that call....
)
Clouds prevented me collecting any more than single RGB subs, and getting too late on a "school night" anyway.
LRGB 15:5:5:5 (Lum 1x1, RGB 2x2 binning)
All 5 mins subs, QHY9 + QHY9 filters + MPCC + IDAS through 8" Newt
