This is the first time I've imaged the Lobster nebula, and I'm very happy the way it's turned out. Some more data later would be nice, that's if I can find another couple of hours cloud free.
Tuesday and Wednesday look promising, probably jinxed it now saying that.
Equipment.
8" Newtonian astrograph f/4. on HEQ pro 5 mount. Orion mini guider.
Unmodded canon 1100D, baader coma corrector, cooler box.
13 x 9 minute subs, iso 800, stacked in DSS, processed in PS7.
Cheers,
Justin.

loads of the red stuff there Justin. If you can pull that sort of response out of a stock 1100D, surely you must be wondering what potential that camera of yours holds if you were to do a filter mod....
Lots to like about this image Justin with plenty of interesting bits everywhere. The background looks a tad red to my eye, be interested to see that toned down to see what a difference it might make to the nebula contrast?
Nice work though and good luck with finding that clear sky

Hi Richard,
Your right, I have thought about modding the 1100D, just can't bring myself to do it. The dark skies I have seem to help a lot with capturing faint nebulosity.
Think I'll eventually get a CCD to capture more HA.

Thanks Mike,
Yep I'll tone down the red a little more. This area of sky seems be to very red, I think there's a lot more emission nebula there that's just beyond my reach. In PS I do an equalize to see what I'm dealing with in backgrounds and there's a lot of red in this one.

Good stuff Justin. You just need to watch your colour balance. Check your histogram. The stars in front are blue but for one that is yellow. If you boost your levels in the green and blue then lower you red you'll be spot on.

Thanks Marc!
I have more data from last night, so will start from scratch, had a quick fiddle with the current image and applied your suggestions.
