Modules & functions w/ ML:
• Long exposure (Bulb) with mirror pre lock-up @600s
• Dual ISO @1600-100
• ADTG/DFE Gain: -23 w/ e-gain @0
• Black offset level: 256 ADU
• White clipping level: 16383 ADU
Setup:
• 5D2 w/ cooling capability, device off (passive mode), sensor temperature @12°C (end of exposure)
• Optic: 400f/2.8L mod. working @f/2.6
• Filters: RGB composite with Hα - OIII - Hβ, 1x600s per wavelength
• Astronomical mount for sideral tracking w/ pseudo random dithering between exposures
