Thanks, Tim. We don't think we could do much better without going to altitude.

Beautifully done.
Thrilled you like it. Just had a check round a representative area, comparing the faint red fellows with the ESO shot. The vast majority seem to be real, though there's the odd hot pixel.

Just one thing you might not be seeing is that stars away from the glob at the top and bottom of the image appear to have faint tails pointing downward. Can you see that? They appear to be in line with the diffraction spikes but very thick directly underneath.

All in all a fab image. One of your best in my opinion.
We're delighted that you like it Paul. Those little vertical drips are a great puzzle. They've been there ever since we bought the Aspen. Weren't there before with the STL-11000M. It's not classical blooming, because they occur on faint stars as much as on bright ones. We really ought to try taking the camera off and bolting it back on at 90 degrees, to see if its optics or chip, but mechanically that would be a nightmare.

Greg.
Thanks, Greg. The 20" isn't especially sharp, but it's good at catching photons.

Cheers, Marc! We'd done a brief 3 minute-per-channel shot last year, to test focusing. That told us we weren't going to burn out. Last night we had a couple hours to spare before the Eagle was out of the mirk, but Omega was just about straight up, and seeing was good, so it was the perfect opportunity.
