M33

M33 - Combined data from 2011

In the picture above, I've combined 2011 M33 images from two sites, Cascade Meadows RV Park and Indian Trail springs, which includes two five minute images and five ten minute images. Maxim DL was used for the calibration, color conversion and stacking (using the "sdmask" option for combining them). Stretching was done in Photoshop (PS), followed by a local contrast enhancement and space noise reduction using Astronomy Tools add-ins on PS. Noise Ninja was used selectively in the periphery of the image and then some color balancing was done (again in PS). Compare it to the other image of M33 in the last blog entry, where images came from one site, lacked dark calibration, and did not have the benefit of Noise Ninja. I think it is a pretty good improvement, though the color is still a little 'off' in the periphery.
