As for the technical side, 1hr subs at 0.55 arcseconds per pixel... I will keep on dreaming
Thanks muchly, Suavi. Hope we haven't over-sharpened it. Perhaps half a tad.

The question of how long an exposure is best for us is still slightly unanswered. I often wonder if some photo-electrons that one has captured early in an exposure ever leak away late in the exposure. Hope not.

Thanks Steve!

Thanks Rick. There were more than we expected. The two colliding galaxies were a bonus.

Cheers, Rom. Nice to hear from you.

Thanks Colin. Agreed.

Hi, Jerome. We agree with Colin's comment that the blob toward 9 o'clock is almost certainly a dwarf galaxy which just happens to have a couple foreground stars confusing the picture. We're also tempted by Colin's explanation that the aqua star could be a quasar. We once photographed a galaxy in Libra which had nineteen catalogued quasars in the image. They tended to be implausible super-saturated blues, which made them easy to find. Dunno. Could be just an artefact.

Hi, Peter, Lovely to hear from you. Glad you like it.

Thanks Colin - we think your explanations are very good. Don't have any super-good plate solving capability against a big catalogue. Next free moment I'll plate solve roughly against Tycho, find the coords of the probable galaxy, and see what I can find. Anyone beats me to it, so much the better.

This shot was interesting in that even after 3 nights (over two consecutive rainy months) it was looking pretty boring, but yesterday we added just 9 hours of colour, and Hey, Presto! it looked much more endearing.
