I've combined 10 hours of narrowband data with about 9 hours from a couple of years back. Yet to work out how to use another 6 hours of RGB data in any way that improves the image.
RC8 on Mach1 (and NEQ6 two years ago) with a ZWO 1600MM-C.

Comments/critique welcome.

P.S. If I'd managed to use the RGB data, I would have exceeded 24 hours of data and been able to deploy my
