A Monkey and a Jellyfish, Ha

IC 443 and NGC 2174

January 17, 2016

My first Hydrogen alpha image! Yay! Many people think that you cannot use a Ha filter with and unmodified DSLR, but my 12nm astronomik filter worked fantastically on my unmodded T3i. Very interesting FOV too, provided by my new Canon 200mm F/2.8L lens. Enjoy, HaRGB on the way (although the moon may delay me).

Object details:
At the focal point of the image, the Monkey head nebula (NGC 2174), an emission nebula in northern Orion, dominates the frame. IC 443, also known as the Jellyfish nebula, is a supernova remnant. Just below it lies emission nebula Sh2-249. Above and to the left of the Monkey head is Sh2-247, and the small emission nebula to the lower right of the frame is IC 2162.
