Description

Decided to tackle the infamous Rosette Nebula region (NGC 2244, Caldwell 49) end of March before it moved too far in the western sky. This beautiful object lies in Monoceros at approximately 5200 light years. The nebula is a large cloud of gas and dust and a region of intense star formation. It is closely associated with open cluster 2244 that lies near its center. Other open clusters have been identified in the region, including, NGC 2237, 2238 and 2239. Because this area is difficult to observe, it’s identity has been made piece by piece. British astronomer John Herschel, German Albert Marth, and American Lewis Swift have all identified parts of it. As an astrophotographer, I’ve seen what other imagers have done and my first take is average at best. Over the past few months, I’ve been experimenting with different post-processing techniques in an effort to bring about more natural color. I think the main task now is to improve my SNR by increasing integration time. This DSO probably needs a minimum one hour of exposure time. In this particular project, I took two sets of images. The first one was 35 light frames, ISO 800, 8 sec exposures (no flats, darks or bias frames) Camera Raw conversion, the second was 50 lights, ISO 800, 8 sec exposures (no flats, darks, or bias frames) Camera Raw conversion. Total integration time Set One 4 minutes 40 sec. Set Two 6 minutes 40 sec. Love to take on this project again to give it the time it deserves. The equipment used, SkyWatcher Travel Adventurer mount, Canon 77 D mod Ha camera, Sigma Art 105mm f/1.4 lens (105x1.6=168mm effective Focal length.) C&C Welcome
