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.

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.
