Good capture Matt, & nice reprocess Mike!
I had a crack at it too, hope you don't mind. I only worked with the one on the right.
Purely in the name of experimentation I wanted to see the effects of different methods in Astraimage. Heres one without deconvolution ;
I saved Matts image as a bmp & did the RGB split in Astraimage, unsharp mask 2.0 was applied on all 3, recombined. Unsharp mask of 2.5 was applied. A gamma reduction of 0.8 was applied. Screen shot it & taken into my editor (Picture Publisher) saved as a jpg, reduced in size. Thats it.
I found it interesting that it got rid of the blue hue just by doing that without deconvolution!

OK
For those who want to download the full 109 frame avi from which these images have been produced, here's the link:

astra image will darken some images with deconvolution. I do not worry as a auto colour in photoshop corrects it straight away.

But back to your prior post Davo
That's amazing how your top left image (combine) has the same overall blue colouration.
Even your avatar has a blue tinge.
Any idea why?

working with the split r,g,b and processing them all differently ie differenet wavelets and deconvolution will darken / brighten each channel. upon recombining, the colour will be off. The auto colour will fix it though in PS

Wow
That's really something, Mike. Thanks so much for going to the trouble of downloading and processing.
I'm really encouraged. Must have been one of those rare nights in Canberra when the seeing climbed above 3/10
Must get this scope out of Canberra sometime and along to a star party and do some imaging alongside you ... and other IIS-ers. See what she can really do
I guess you followed your usual processing path: VD split into BMPs, ppmcentre.and.. RGBSplit (with new software)... run each channel thru regi, stack and mild wavelets, AI (LR decon) and AI recombine back, and then a little work in PS?????
Cool stuff. Again, many thanks

That's exactly what I did Matt. Glad you like it, it was nice data to work with.

Been meaning to ask for days.
In your earlier post in this thread you refer to the above in PS
How is this done? How do you work curves on the centre of the image?
Cheers
