M 56 (Lyr)

The above image was processed with regards to the correct physical star colors. The amount of clarity which is visible was done without deconvolution, the "A Trous Wavelets" in PixInsight were used instead. The lower image was done using deconvolution to get the impression of high resolution because of the lower than average seeing that night (about 3,0" FWHM).
