NGC4565 in Coma Berenices

And what a beautiful edge-on sprial galaxy this is! I made almost 3 hrs of 120-second frames with the ASI183mm Pro and the Esprit. Then I combined the resulting monochrome (Black/White) image with the older C11/Nikon D750 color frames I had from last year. This process included debayering of the color frames into a Red, Green and Blue version. And again recombining an LRGB with the monochrome and RGB frames. Finishing in APP (Background neutralisation, removing Lightpollution ) and in Photoshop.

This is the monochrome ASI image. It is wortwhile exploring it a full resolution in Astrobin, detecting the many little galaxies in the background.

Since the Field of View of the Esprit/ASI is much larger then the C11/Nikon, this image was cropped to fit the color frames.

M106 added more data

I could add 116 shots of 120 seconds, in an attempt to bring out the outer spiral arms more clear. The total integration time is now over 8 hours and this is the LRGB combination below (all shot from Meldert, Belgium). Click on the picture to go to Astrobin.

These 4 nights were more or less used, there was some high-altitude clouds passing by which not always affect the photometer (click for a larger image)
