Iris - slightly wider view

[ampleamp]

The Iris needs no real introduction and i thought i would have one last go at LRGB before astro dark was completely lost a couple of months ago. This image was taken over 13th, 14th and 15th May with my multi-widefield setup before i took it down and revamped it. Subs comprises of 64 x 420s L, 54 x 600s L and 30 each of 300s RGB. No flats were applied to RGB as they failed completely - i got a terrible red cast all around the red stack that wouldn't correct out with standard dbe etc. It eventually occurred to me to try stacking without flats and there was no red cast, so my conclusion was that the red flat at least was defunct. Either way i had already combined rgb and didn't go back and apply/test the g and b flats.

Thanks for looking.
