Thor's Helmet (NGC2359) with 40D

Hi All,

Going through a very busy holiday period where we've had no cloud for about 6 days up until last night.

Had enough of M42 for now so I wanted to do Thor's Helmet and this is my 1st attempt. Certainly not in the same league as Rob's (OzRob) lovelly, recent post but it's a start.

NGC2359 - Thor's Helmet
Canon 40D Modified (Astro)
FLT110 with flattener
17 x 600 seconds ISO 800
19 x Darks.
I took flats but on stacking it was severly warped near the bottom. I guess uneven illumination. This image really needs flat imo.
Stacked with DSS
Processing with CS4. Levels, curves, selective colour, noise reduction, match colour to boost star colours (from Louie's tutorials) and cropping.

This subject really needs a longer FL (probably at least 1500mm)

Thanks for looking and as always, critique/suggestions/improvements most welcome.
