First HALRGB M101

Decided to add in some HA i had collected on M101 bringing out some lovely red star forming regions. Its a bit of a learning curve with this like everything in astronomy as i had to mask the master HA considerably before adding it to the red channel. By masking so heavily i inevitably discarded most of the HA data i had collected which is a disappointment but thats something ill know for future galaxy images.

  1. Excellent Image, the HA filter really adds beauty into the galaxy. I’m looking to get a luminance filter myself to try out.
