Low Key M20

Peter Ward · #1 23-10-2013, 10:09 PM

Armed with a few new processing tools, (thanks Martin

) and being suitably motivated by recent posts, I figured...what the heck.. time to reprocess some old (about 3 years) data.

I know, the luminance layer registration is a tad off... and will be tweaked in time. I was more interested in the dynamics of the image. So...what do you think...dead end? ... or shows promise?

The link is here

Very nice indeed.
Time to do some more re-processing on other pics!

Nothing like new processing procedures on old data to show what advances have been made. Excellent image IMO and great detail.

Looks pretty good to me but i'm an amateur when it's processing skills

Nothing I can say except it looks like a pretty good Trifid to me so I guess it shows promise. Looks like you caught an asteroid going past.

Cheers

on the laptop screen this is very 3D - love the depth and colour Peter

Thanks for the feedback guys... much appreciated. Looks like that processing flow has merit

Great piccie there Peter, though the dark lanes and globs could be just a tad sharper. But that's just my preference

Very inspiring Peter, always dig a closeup on the triffid, and yeah looks a 3D tunnel in there

Nicely done . .

Text book M20. Dusted and back to the cool wall now.

Thanks for the input.... but I like the stars to be sharp and the clouds to be somewhat softer

You've been flying that A380 of yours way too much

AG Hybrid (Adrian) · #13 24-10-2013, 01:32 PM

It looks 3d. neat.

Good old data – it’s a gold mine.
Very nicely reprocessed.

Peter.M · #15 24-10-2013, 04:22 PM

My only comments would be that the low signal areas of the image seem a little blotchy? Its sort of a weird mottled look. And did you desaturate a section to the right of the image? I would mask in the star colours in the desaturated section just so that it didn't stand out so much depending on the reason you did it. It looks like it could have had some weird green gradient or something? Great image on the whole, one I would be proud of for sure!

Appreciate the feedback Pete, but not sure what you mean by blotchy.

Sure, there is some imperfect noise reduction (working on that) but the image has quite a high HDR (or should that be DR

) so there some light and shade within the reflection nebula and some (real) dust toward the edges that might look like processing artifacts.

Thanks guys. Ah..could be better...but good enough for now

Cumulus-granite is always a worry

As an aside Sydney airport has an number of signs that read: if you see FOD, pick it up!

FOD = foreign object damage .

Not sure how you go about picking up the damage.... I suspect they mean the objects that may damage turbines...

That looks very nice Peter, I like it! Did you use PixInsight?

Indeed..much of the heavy lifting was done with PI....but I still need Photoshop for the gilt edges
