It's been cloudy. Very cloudy. I managed to get a short imaging session, so I had to choose a bright target. The globular cluster Caldwell 79 was in the right place at the right time. It is located at a distance of 16,300 light years from the Sun and has an estimated 254,000 times the mass of the Sun. This cluster is about 10.24 billion years old.

Often I like to see how an image is processed from start to finished. Presented in this animation are the main processing steps in sequence from my image of NGC 300

NGC 300 is a spiral galaxy in the constellation Sculptor. It is one of the closest galaxies to the Local Group at 6 million light years distance.

NGC 6188 is a large emission nebula of compressed molecular clouds 4,000 light years away in the constellation Ara. This image spans around 3 full moons and comprises of emission line data for Sulfur-II, Hydrogen-alpha and Oxygen-III, mapped to red, green, and blue respectively.

Centaurus A is a peculiar galaxy discovered in 1826 by Scottish astronomer James Dunlop in Parramatta, Australia. It is ~10-16 million light years away and its lenticular with dust lanes hybrid appearance is the result of a merge of two galaxies.
