Planetary Nebulae
A Planetary Nebula in constellation Gemini about 1500 light years from earth. At first it was thought to be a Supernova remnant, but more recent measurements of the expansion velocity suggest it to be more likely a Planetary Nebula. These are the outer shells of a sun-like star which have been expelled at the end of the active live of the star.

Globular Clusters
M3 is a Globular Cluster in Canes Venatici about 34000 light years from our solar system. As all Globular Clusters it is pretty old (11.4 billion years).

Emission Nebulae
NCG 2174 is an emission nebula in constellation Orion. It is associated to open star cluster NGC 2175 which delivers the energy which powers the radiation of the gas.
This is a final processing result pushing the blue inner part. Normally is it shown in red, result of prominent Halpha radiation from hydrogen.

Emission Nebulae
NCG 2246 (Caldwell 439) is a star forming region in Monoceros about 5000 light years distant. The young star cluster NGC 2244 (Caldwell 50) in the center of this region has been formed from material of this cloud and is pushing the remaining material towards the outside. The nebula will disappear in some million years while still creating new stars …

Dark Nebulae
Dark Cloud in Orion in front of read emission nebula IC 434. Left to bright star Alnitak the so called Flame Nebula or NGC 2024.
This image shows originally very bright halos around bright stars caused by the IDAS NBX filter, which was very bad to this respect. Meanwhile IDAS has released NBZ as a better replacement … and it is really better.

IC 1871 is a star forming region in Cassiopeia, associated to IC 1805 (Heat Nebula), 7000 light years from here.
This is the final version of several different ways of processing this image.

Galaxies
Our nearest galactic neighbor.
This is a reprocessing from the first image I took with the Borg 90FL just with my Canon 60D.

Emission Nebulae
NGC 7000 is an emission nebula about 2000 light years away. It is part of a large cloud complex in constellation Cygnus.
This was one of my first deep sky astro photos in the post-celluloid era. This actually was the starting point of all you see on this site.
