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.

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.

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.
