Rosette Nebula, Caldwell 49 in H-alpha
Star forming nebula, complete with stars. 5000 light years from us and 50 light years across. Includes nice Bok Globules in NGC2237 at lower right.
Quite close to a bright moon tonight, but the Ha seems to have cut through okay and the subject is bright enough. I had less success with the Jellyfish Neb., even with double the time; it's just too dim for the conditions. Quick processing, but it looks okay. I'll probably tidy later and add in some RGB if the combination of clear sky + no moon ever happens again in my lifetime.
8 x 600s Ha, Esprit 100ED, Atik460EX -20C, AZEQ6, PHD2/ZWOASI100, Altair 60mm mini-guider. Processed in Nebulosity.
