Messier Objects
I highly recommend a book on Charles Messier and the creation of this catalogue - Atlas of Messier Objects, 2008 by Ronald Stoyan.
Note: This gallery should be automatically sorted by Messier #.
Messier M83 NGC5236 Southern Pinwheel Galaxy - 14/04/2012 (Processed cropped stack)
2X Powermate with borrowed f/4 Newtonian bringing the configuration to f/8. Cropped to show M83 only from the central portion of the image to minimise coma distortion. Whilst the image scale is double that of the prime focus the sub-exposure time was not 4X (only 2.5X) and lacks detail and defintion compared to it (same night).
