Second attempt at Omega Centauri
I posted a first shot at processing a quick & dirty attempt at Omega Cen last night. I wasn't happy with it and a few people suggested a few small changes; I had another shot using a very different processing method and am much happier with the result.
90 x 20-second subs, 30 each at ISO 800, 1600 and 3200. Stacked into 3 TIFs using DSS, then those three TIFs stacked again into one. Processed a little before exporting to Lightroom for a final tweak.
It wasn't guided, I didn't even drift align - just pointed it vaguely south - so some stretchy stars, but happier with the processing. Also delighted how low the noise is considering no darks or bias. (No flats either, because I've never yet had success using them - without fail they've completely ruined my images every time I've tried. No idea why.)
Anyway, does this look okay to you? It's certainly a lot better than my first attempt but I'm struggling with the colour. Suggestions encouraged as always.
