Description

This galaxy season was pretty successful. If I counted right, I collected more than 70 hours of integrated exposure time on galaxies which is a lot for me. But now I am pretty tired of those small DSOs... Cygnus is still low on the horizon at the beginning of the night but rises quite high afterwards and contains some really big nebulae. So I went for the Sadr region with its Butterfly nebula. The image has an RGB basis enhanced with duo narrowband data. I am glad that the nebulae are back.
