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.

Gear:
Canon 200mm F/2.8L
Canon T3i (Unmodified)
Astronomik 12nm Ha clip filter
iOptron ZEQ25gt
Orion SSAG
PS, DSS, Carboni’s Tools, Gradient Xterminator, PHD

Image details:
4hrs of 5min exposures, ISO 400, F/3.5, VERY light polluted area.

Thanks for viewing!
