This was one of my early images, long before I had color capability. Later I took the color data but when I tried to combine the two the luminosity image I'd taken early on didn't match as the film plane wasn't perpendicular to the optical axis so image scale changed from the lower right to the upper left. The color was taken after I fixed the problem. With all the nasty weather I tried again. I broke it up into 6 pieces, matched each then recombined them. It worked rather well but took a lot of time. The large blue galaxy is NGC 7320 is a foreground galaxy not related to the others. It's around 40 million light years distant while the interacting group is some 270 million light years away.

Nice!

Fantastic effort in combining and processing this early image, Simply beautiful! Clear Skies

Hi Rick,

Well done, the quintet looks really, really nice. Very interesting seeing how galaxies collide! (Debatable)

Lovely shot and now I am really curious. Did you use a deconvolution on the colour stacks to bring the images into alignment?

Kind regrds

No deconvolution used. I rarely use it. I just cut it into 6 pieces, morphed the lum plane in photoshop until it matched the RGB plane then combined. Did that for each of the six sections then put the pieces back together again. When I tried working with the entire image I'd get one part right but another would just get worse and I was getting nowhere fast. Working in pieces worked but it did take an entire evening.

Rick

whow Rick,
that one is wonderful! resolution and clearity is fantastic!
I think seeing was generous this time!
sorry to learn about the technical issues, but you managed that properly!
very cool image of the couple!
