Well, we're in the land of the guess now and I think you're 'in the zone' with the colour but, perhaps, towards the blue end of the zone? My estimate of OIII might nudge it to towards the green a touch but that's just me. You have strong signal for this strange object and, if the image were mine, I'd be more concerned to pull out more structure, if possible. In some of the deepest renditions we see something like a loosely wound coil spring along its length. An extended helix, if you like. I wonder if this might be latent in your data? I would explore this direction in Photoshop rather than PI. But what happens if you run LHE? I'm sure it would damage the global image but if just applied to the Squid?

In Ps, Noel's Actions 'Local Contrast Enhancement' will do a similar job, or you can do a masked stretch through an equalized mask. It's all down to increasing contrasts on a scale considerably larger than sharpening, though the principle is similar. Olly Link to comment Share on other sites More sharing options...

Quite useful. Then I also tweaked it towards green in curves which also brought some more signal into it I think. So here is the more green and a bit more dynamic squid. Thanks for the tip Olly! 7 Link to comment Share on other sites More sharing options...

Yes, that little squidling down to the right is a nice catch, usually ending up outside the frame of Squid images. I wonder if it has a name, or at least a number.

pipnina Posted November 26, 2020 Share Posted November 26, 2020 I'm more than a little surprised a post I made five years ago has been referenced this week! Even I forgot I even made that one! Thanks for the memory trip and for the beautiful astrograph! 1 Link to comment Share on other sites More sharing options...
Laurin Dave Posted December 18, 2020 Share Posted December 18, 2020 Congratulations , just seen this image in Astronomy Now together with a write up by @ollypenrice extolling the virtues of colour CMOS .. if I hadn't just bought one and seen what they can do I think I'd need a lie down!

Dave Yes, miracles still happen - I am not a subscriber but I was promised to get a copy. I think ZWO owes Olly and me a camera each 3 Link to comment Share on other sites More sharing options...
