Description

Trying a different data collection approach as suggested by Jon Rista on CloudyNights - limited RGB subs (12 ea here) and as many Lum as possible; only able to take 30 Lum so far due to time constraints, he suggests 50 to 100. From my locations at least (generally 20.8 mag/arcsec^2 or better) this seems to work OK. Lum frames were 120 s, RGB 280 s, WO FLT132 with 2x PowerMate. Some corner star elongation, I think the spacing with the ONAG is too much for the PowerMate. 50% reduction. Comments welcome!
