Thoughts on how to improve...?
I did my best image a few weeks ago, of Orion (on literally the only other cloudless, moonless night we've had for about 17 years). Achieved it by getting stacks of different ISOs - ie 25 x ISO 800, 25 x ISO 1600 etc - and exporting different versions of them (lighter & darker) from DSS, then stacking the resulting processed TIF files, then using Photoshop to combine various elements. Worked great.
Tried the same thing again tonight on last night's capture of Omega Centauri. Not thrilled with the result. For one thing, the colour was all over the damn place from stack to stack. Not seen that before. Maybe a neighbour's back yard light came on and threw off the white balance. Or maybe it's just my cheap DSLR behaving like a cheap DSLR.
Anyway. Any thoughts / suggestions for improvement welcome. Cheers!
