Description

Color image obtained with a Nikon D800 on a Skywatcher NEQ6.

Rev.D: Newest version was obtained with GSO 8" F5 Newton and Skywatcher Esprit 100 recording luminance subs with the mono Nikon d5100. I integrated the exposures from the two telescopes with Pixinsight. I thought i did rescale the exposures to obtain a uniform pixel scale but somehow a grid like pattern emerges.... I want to combine this luminance data with the color frames obtained with the D800 and at some point also with some Ha data which i started to capture.

Rev.E: Noise reduction with TGVDenoise in Pixinsight
