Details:
Most Messier objects are bright and easy to observe and image. You would think that the Crab Nebula or M1, the first object in Messier's catalog, would be no exception. This supernova remnant over 6000 light years distant was so bright in 1054 AD that it could be seen in daylight. Today, 30 seconds was the required exposure time just to see the object to get it centered in the frame. This image consists of 115x3minute stacked calibrated light frames recorded over 6 separate evenings from cloudy Southeastern Pennsylvania. I used a Celestron EDGE HD 9.25" with a 0.7x Celestron Focal Reducer and OAG. The camera was a modified Canon 1000D, DSLR ISO800. The light frames along with their associated flats, darks, and bias were aligned and stacked using ImagesPlus. Image enhancement was performed using ImagesPlus and PS5. Guiding was done using a ZWO ASI120mm and PHD2.0 software.
