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.
NGC884, NGC869
A beautiful double cluster of NGC884 and NGC869 in the constellation Perseus. These objects are pretty bright and were already discovered by the ancient Greeks. Here captured using an OSC camera.
NGC7789
NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. She was the sister of the well known William Herschel. When looking at this object visually the loops of stars and dark lanes give the impression of a rose, that’s what gave it the nickname Caroline’s Rose.
M35
A nice combination of two star clusters. M35, an open cluster in the constellation Gemini. Only a few hundred stars. The second cluster is NGC2158. It is much further away and therefore looks much smaller. Its old red stars make a nice contrast with the bright blue stars of M35, creating depth.
