Sh2 170 Little Rosette Nebula HOO-RGB

Sh2 170, is a rarely imaged nebula, also known as the Little Rosette Nebula. It’s an H2 region located in the constellation of Cassiopeia. Located about 7,500 light years away in the Perseus arm of our Milky Way galaxy. The bright star at the nebula's centre ionises the surrounding hydrogen gas and causes it to glow.

A challenging project that was surprisingly tricky to process due to very low surface brightness. Imaged in Ha and Oiii with RGB for stars.
Taken over 6 nights at the Los Coloraos complex in Gorafe, Spain.
Processed in a natural palette.

Imaged using the Celestron C14 Edge HD telescope in dome 4 at Turismo Astronómico, Los Coloraos observatory in Gorafe, Spain.
