Mosaic of 2 fields - M42 and Running man nebula.
7 x 240 sec for Running man
7 x 240 + 5 x 30sec for M42
(ICNR, flats etc performed, all subs ISO 400)
Each field 240sec field stacked then merged together, stretched, etc. 5 x 30sec frames stacked and layered in last. Whole thing tortured for a while in PS.
May not convince the gurus here, but I'm reasonably happy for a first try and this sort of black magic. One minor problem - my final cropped frame is probably only a smidge larger FOV than the 450 can manage with a single frame anyway I suspect (cf first ever M42 in 2nd pic). Ah well, educational exercise on a cloudy Fri night.
