Not all (that) glitters....

A reprise of my earlier post.

This one was tough. How do you process black blobs on a starry firmament?

The file is a little large (2 meg) so may take a while to load. Those that like to zoom in may spot the tell-tale RGB trail of a couple of minor planets :)

Anyway, enough rambling...

Barnard 92 (http://www.atscope.com.au/BRO/gallery100.html)

Pity there wasn't some way to intelligently identify and mask complex shapes, especially dark ones and then do a separate image processing task on them whilst leaving the background for later processing.

Very good piccie, though:):)

Top shot Peter and nice reprocess. I love those golden sandy fields sprinkled with blue diamonds. Top stuff. :thumbsup:



You can mask all the stars then stretch and process the background separately without affecting stellar profiles. When you're done you dump the stars back as lighten. (unless you're Fred)

My vote goes for your first rendition Peter. The stars seem to be a bit overdone in this one while the first seems so realistic and the stars look more like gems to me.

[Peter Ward]

Thanks Marc.... that was the intention! :)

[Peter Ward]

I suspect it's due to the fact the image scale has been reduced quite a bit. The original 4k x 4k image has stars with nice soft edges.

Thanks. To paint or not to paint? ..that is the question! :)

[Peter Ward]

Ok... larger version uplaoded (http://www.atscope.com.au/BRO/gallery100.html) or as Kim Jong Sung said in team America...

...just a 'rittle bit more :)

[TrevorW]

Not your run of the mill target and well done IMO

Very cool field Peter, lots to seek out and investigate...kind of a Where's Barnard? :P

Mike

Thanks. I like it. The cat likes it (suspect he sees a mud-crab in there somewhere)




Thanks Mike, I was really unaware of this particular neb until I did that very wide-field H-Alpha B&W mosaic last year... Seemed worthy of further investigation :)
