Description

My first attempt at enhancing RGB color data with Hydrogen-alpha data. Not only did it bring out the gases inside M81, it brought out the jets in M82 pretty nicely. I don't think you can ever have enough Ha for M82; even with almost 10 hours of Ha the jets are still pretty faint.

Hope to collect even more data on this in the future.

Description: Up to 17 hours on this now - I'm starting to see hints of the IFN in the raw data, so I'm excited and will keep going on it.
