With Comet Garradd starting to be nicely placed for observation and imaging I wanted to try my hand at imaging the comet and gear up for perhaps brighter Comet Elenin C2011 X1.
I have tried guiding on the nucleus (Just Luminance) of the comet but in the end didn't really know how to process the subs other than what's on my home page here. The next night out I tried guiding on a star and imaging R, G and B but really resulted in the same outcome. I was only taking three minute subs and the comet nucleus still looked circular.
What I would like to do is to get some good chrominance data (RGB) combine the images while removing the stars leaving the comet head and then paste that image back into a LRGB image of that same star field without the comet in the field.I think it can be done using Maxime, CCDStack and Photoshop. I'm just not sure how to do it.
Does anybody have any suggestions on how I might achieve this?
If the clouds and Moon co operate tonight I'll be going after more data.
