NGC 7822 narrowband

Homebrew false colour palette to help bring out the different regions. Interesting “pillars of creation” shown in the inset. Not the famous ones in the Eagle Nebula, but this object, along with the Elephant trunk nebula, also have similar features. A young star forming region in Cepheus, contains Sh2-171 and cluster Berkley 59.
It contains one of the hottest known local stars (marked) BD+66°1673, a O5V eclipsing binary. This star illuminates much of this nebula and forms the “pillars”. It is 45,000K and 100,000 time more luminous than the Sun.

The Tribble Nebulae NGC1624/Sh2-212 and Sh2-211

An obscure one in Perseus. The larger is open cluster inside an emission nebula NGC 1624, also known as emission nebula Sh2-212, the smaller Sh2-211. Now known as the Tribble Nebulae after “Star Trek: The Trouble with Tribbles”. The dark patch top right is the dark nebula Barnard 20.

Double Cluster NGC 869 and NGC 884 / C14

Revisiting an old friend. Two rich open clusters at similar distances from us of 7,500 light years.
