Rosette Nebula, HaRGB

Happy valentine's day!


I finally had a clear (and cold!) night to capture some RGB data to go with the hydrogen-alpha from a few weeks ago. (My OIII efforts during the full moon were a waste, too many gradients thanks to the moon.)


So here is a first draft -- I will have another crack at processing this one soon. Somehow all the orange/yellow stars got washed out, and the background is somewhat noisy.


In terms of integration time (minutes), for Ha:R:G:B it's 180:45:45:45, with the RGB channels binned 2x2. So not a ton of colour there.


Thanks for looking,
