Description

This is my first attempt at narrowband from my backyard. I did an SHO image of the Lagoon Nebula from a remote rental (iTelescope) in Australia. I got a top pick for that. (my first and only) This time I did the Cresent Nebula, a boring object I'm sure for a lot of you pros! However, after I aquired the data, Dean Koenig (Starizona), suggested a combining technique (Pixinsight) I had never heard before. This image being HOO would, I guess, normally be combined in 'Channel Combination', which I tried and which was underwhelming. He suggested using LRGB combine, put HA in L and R, Oiii in G and B, and play with channel wieghts. I knocked R down to 50%. This is the result. Way better than channel combination. BTW, this is only 20 Ha's at 240sec and 20 Oiii at 240sec. I'm learning. Enjoy...
