Description
NGC6888 is an emission nebula in the constellation of Cygnus. Its distance from earth is about 5000 light years. Being in Cygnus it is directly in the plane of the Milky Way, which shows by a super-rich star field. Its size is barely around 18’×12′, just as small as most larger galaxies in our current night sky.
It is primarily a H-Alpha and OIII emission nebula as you can tell by the red and blue/teal colors present. Sadly I had no narrowband filters present to capture the nebula in its full glory. Thus I had to rely on my Nikon for the colors and the 383L+ for the lightness information.
Technical Details
Technically, a lot went wrong with that image, most notably the strong coma present on the Newton which came from absolute miscollimation. Next time I’ll go out I will definitely recollimate my scope before I attempt to shoot images. Nevertheless I am somewhat pleased with the result given the short total integration time.
