M45 colour balance
Posted: Thu Nov 23, 2023 12:09 am
Well here's another query back to back on my last one. Things have piled up since I haven't visited the forum for so long 
I took this image with an 11 inch RASA f2.3. I think there is about 88 min of exposure with 4 minute lights which is a lot of exposure with such a scope. I was amazed to see to see how much red came through. No amount of colour balancing can get rid of it. I know that m45 is a blue reflection nebula over top of Ha but I've never seen this result before. Could there be something wrong with my data? If anyone is interested I can forward the stack ( it one file OSC). Thanks!

Forgot to mention its a 2 pane mosaic as remote scopes are set in their orientation.
