Hi Guys.
My latest from the other night. A bit too much noise reduction I think, resulted in a bit of a "painted" look at 100% crop. Pretty keen to get a new mount for the camera so I can do some longer exposures, will be modding the 550d and getting an LP/IR filter too...
About 1/3 of the image is cropped due to field rotation being too evident.
Canon 550D
50mm f1.8 @ f4.5 iso1600 20sec
77x Lights
31x Darks
101x Bias
Edit: re-sized version looks horrible
