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.

A color LRGB image of NGC4565
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.

M106 8.5 hours of LRGB with the Esprit 120mm ED and the ASI183mmPro, Baader LRGB Filters

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)

M106 in Close Up

M106 image on March 29-30th 2019, ASI183mmPro and Esprit120mm LRGB

A first LRGB attempt on this subject. I have never imaged M106 before, always exciting to explore a new galaxy. I find the outer spiral arms are not clear enough: need to add more data…

This was an LRGB combination using AstroPixelProcessor.
