NGC5139 - Omega Centauri

Hi all

This was taken on the Saturday night at Wee Jasper (well, actually Sunday morning). Saturday night had the longest clear spell, after the clouds parted at about 10:30pm. It was clear till about 2am, in which time I captured Eta Carinae (still processing) and Omega Centauri.

Unfortunately my run on Omega Centauri was cut short due to the clouds - I had a run setup to take 10x10s, 10x60s and 10x180s, but I only managed to get the 10x10s and 9x60s before clouds rolled in.

- Scope + Camera: ED80 + WO 0.8x reducer + unmodded Canon 350D.
- Mount: EQ6
- Guiding: Guided through 400mm f/5 refractor, using DMK21AU04 + PHD software
- Lights: 10x 10s + 10x60s @ ISO800, flats calibrated.
- Darks: ICNR used
- Flats: 15x 1/3s median combined
- Processing: ImagesPlus for Flats Calibration and Deep Sky stacker for registration and stacking. Photoshop for everything else.

I'm not happy with the image because there's absolutely no colour I needed the longer exposures to get the deep colours, but didn't get a chance.

Anyway, it's a tease for me for next time.

Thanks for looking.
