Comments This is one of those images you never seem to be able to complete because of weather. I was only able to collect 40mins in H-a during August. I decided to play with Noel Carboni's AstroTools synthetic H-a color. It does a really nice job.
Persistance pays off, after September's New Moon cycle and an unseasonal cool spell I captured the last 20mins in H-a and all the RGB's. The H-aRGB image was much more difficult to process.
