This is a bit of an experiment, with image data combined from two different scope/camera setups. Luminance using a "lucky imaging" approach with a high frame rate camera with low read noise (< 2e)
Luminance = GSO 200mm f4 with a Point Grey Chameleon3 IMX264, 650 x 12s subs (captured with Firecapture, stacked with Autostakkert 2.6.8 with dark calibration only).
RGB = Vixen VC200L f6.4 with a QHY10 Color Camera, 23 x 600s subs, camera temp at -30C
(captured with SGPro, stacked with Pixinsight 1.8 with full dark/bias/flat calibration)
Combined image processed with Pixinsight 1.8
The Point Grey doesn't have active cooling, but I have retrofitted a heat sink and fan. Sensor temp was about 14C
