I decided to make a high res-HDR composition of the Trapezium star cluster inside M42. Mostly to check if my gear still worked after 4 months of cloud coverage here in Belgium
Trapezium stars: 500 x 0.5 sec Lum filter with ROI, drizzle stacked best 70 frames
Core region: 20 x 5 sec for each RGB filter
Outer region: 20 x 60 sec for each RGB filter
Original image is a crop, shown at the native resolution of my imaging system.
The mouse-over view shows the location of two Herbig-Haro (HH) objects and one of the larger protoplanetary disks (proplyd 244-440). The Hubble Space Telescope discovered many more proplyds in this region, but most are too small to be resolved in my data.
The brightest star in the trapezium cluster (C) is a massive O-type star with a visual magnitude of 5. The fainter 11th-magnitude E and F components are located just 4.5" away from A and C, and I was pleasantly surprised to see both E and F resolved, as the latter is notoriously hard to separate from C.
