Finally got the chance of testing my newly modded Webcam. In short, it's a long exposure toucam with a replacement CCD sensor. It is monochrome, larger, and *much* more sensitive. This is a stack of 30x8 second frames, dark subtracted. I think this camera may be sensitive enough to try using a barlow on this target.

The telescope was the usual 8" newt. There was nothing else in the optical path.
Nice.
Combine this as an L channel in an LRGB image and you should get a nice result!
I tried that earlier with the M27 image and taking chrominance from my M27 from last year. Unfortunately there just wasn't enough information in it :sad:
I might have a play tomorrow and apply the chrominance from my M57 from a couple of weeks back.
