Cheers Alex :-)

I didn't really spend that much time doing OSC with a dSLR before moving to a mono CCD. But it's been a long time with lots of equipment issues, so almost all of my (limited) stuff has been mono, because I always get L and then figure I'll get RGB later, but later never comes.

All good fun though, at the early point of a learning curve... best place to be!

Thanks Rick & Atmos! I did try to do colour calibration with the linear data but it went from having a strong yellow hue over everything to having a slightly more olive, but still mostly yellow, strong hue over everything... so I tried it with the non-linear data and that seemed to work better.

I'll have another crack at calibrating the colour when it's linear and see how I go... must be some setting I didn't have right.

Edit: Just had a quick run through it. I think it has lots of potential. Will do it more carefully tomorrow.

Thanks Geoff! Having you say "lots of potential" is a pretty big compliment given the work I've seen of yours on Astrobin. Looking forward to seeing what you can do with it.

I was able to pull out some good detail of the original L data, probably the best I've managed with a broadband subject... but trying to do it with LRGB has left me scratching my head.

The colour is extremely muted after I combine and when I try to tweak the data it just washes it out more... and then when I up the saturation it makes the data look bad, and the colour look cartoonish. Lots to learn when it comes to processing colour... looking forward to the challenge

Here's the mono version I did with the original L a while ago. Adding in the synthetic L dropped the noise by roughly 1/3 so there's a decent amount of detail in there I think, if you're actually competent in processing.
