M77 | Arp37
M77 is a nice small galaxy in the constellation Cetus. It has a wide area of gaseous rings around it, most of which could be pulled out in this image, due to 20h of exposure. M77 is also listed in the Arp Catalogue, as Arp37.
M16 | Sh2-49
M16 is also known as the Eagle Nebula, but the central part of this nebula is made even more popular by the Hubble Telescope, and is nick-named the pillars of creation. Here in a narrowband version with a total of almost 40h of exposure.
M4
M4 is a globular cluster in the constellation Scorpius. It is located at a distance of 50,000 light years from Earth. During processing some interesting green stars stood out which appear to be RR Lyrae variable stars, often found in clusters. The intense green colour is an artefact of the way broadband images like these are taken.
M82 | Arp337
M82 is often photographed together with its close neighbour M81. But the cigar galaxy as it is also called, is a beautiful example of a starburst galaxy and deserves the attention on its own.
