I have finished an image of NGC2403, a fine galaxy in Camelopardalis, and have posted it in my gallery. This galaxy is a member of the M81 group and is approximately 8 million light-years distant. There is a bright emission nebula and open cluster within the galaxy that has its own NGC number, NGC2404. I reproduce my image here with the location of NGC2404 indicated.
This image is my most ambitious effort yet with my Obsession dobsonian. It is composed of 1221 subs, each of 10s duration, for a total of 203.5 minutes of total exposure. The images were captured on February 14, 15 and 16, 2015 at Zephyr Ridge Observatory. I used Pixinsight software for processing.
