Feels good to be back shooting nebulae again! M20 is a stunningly dual colour region captured here with separate R, G and B runs and broadband luminance. If you aren’t sure what that means, basically I’m shooting with a black and white camera (ZWO 1600mm) but instead of narrowband filters with small bandpasses for chemical signatures, I’m using broadly open filters across the spectrum so the result is a more natural, more realistic representation of the objects natural colour palette. I have increased the saturation of the colours to make it bolder however.

Still working on taming this new setup (Celestron c11 Edge HD / 0.7x reducer / CGX) to get the most of our it but this is a good hint at what it’s capable of. Some star bloat and skew and internal reflections from the ZWO glass on the bright stars which is a problem.

Red : 12 x 3m
Green : 15 x 3m
Blue : 11 x 3m
Broadband : 37 x 3m
Total Integration Time : 2.25 hours over 2 nights.
