I know M42 has been done to death, but I wanted to go pretty deep on this one. This is a 4-panel mosaic taken with an EdgeHD14 and Hyperstar at f/1.9. Camera is a QHY10 OSC. Each panel is 50x180s with another 50x10s and 50x30s for the center to preserve the core. The only thing I did at the scope was roll off the roof and plug everything in (automation for that is coming soon). SGP took care of the rest. What a joy it is to image while sitting in the warm easy chair drinking an adult beverage while SGP is hammering away in the 15 degree cold producing stunning images.
