With the full moon gone, I could take colour images of this object and combine it with the previous Hα data

There are a few different techniques for doing this. The Hα data can be used to replace the Red of the RGB colour data, or can be added to the RGB data as a luminance layer in Photoshop. I used the luminance technique as it gave slightly more detail

Camera: Canon 1000D (Ha Modified) with Astronomik CCD CLS Filter
Scope: Skywatcher Equinox 80 with Televue TRF-2008
Mount: HEQ5 Pro with ASCOM control
Guiding: Orion ST80 with QHY5
Software: Canon Capture, PHD, Stellarium
Exposures: 15 x 10 mins (RGB), 20 x 10 minutes (Hα) = 5 hours 50 mins total
