Crescent Nebula (NGC 6888)

The Crescent Nebula, or NGC 6888 as it is formally known, is a distinctive emission nebula that stretches about 25 lightyears across and is located about 5,000 lightyears away from Earth in the Cygnus constellation. Discovered by William Herschel in 1792, the Crescent Nebula is produced by a type of star known as a Wolf-Rayet.

Messier 17

                                    

M17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy. The Omega Nebula was discovered in 1745 by the Swiss astronomer Jean-Philippe Loys de Chéseaux. It is located 5,500 light-years from Earth in the constellation Sagittarius. The nebula has an apparent magnitude of 6 and can be seen with a pair of binoculars. M17, which appears near M16 and M18 in the sky, is best viewed on clear nights in August.

Messier 31 (The Andromeda Galaxy) 9 Panel Mosaic

                                         

This 3x3 mosaic of M31 is my largest project so far. The 9 panels total 6 hours of exposure, using my QHY533M and a luminance filter. 36 files where stacked using Pixinsight into the nine raw panels. The mosaic assembly was done using Pixinsight (image solver, mosaic by coordinates, and gradientmerge mosaic). Further processing was also done in Pixinsight and Photoshop.
