I've begun to capture star clusters when it's inadvisable to image fainter objects due to moon light pollution. I also quite like them since they provide a very good basis for practicing star field processing, which I find quite challenging.
For this open cluster I used 600s subs which caused my camera to enter its non-linear, whilst this did not create saturated stars it can distort colours. I therefore decided to use the Pixinsight script Repaired HSV separation which may be used to repair non-linear data - it attempts to put the correct colour back into the star cores by examination of the surrounding pixels.
I also shot sum Lum data in order to create the "glowing" star effect that I like which to me also looks more natural.
LIGHTS: L:5, R:10, G:9, B:8 x 600s. DARKS:30, FLATS:40, BIAS:100 all at -20C.
