I'll be back...

Finally manged to get out with my ATK the other night. Moon was low
in the west but the seeing wasn't too bad. Next time, I need to leave
enough time to complete the thing ;-)

A bit contrasty but the 200mm Mirage + the ATK 1HS II is a nice
combination.

A lot of detail there.

Good results but the scale is too small to appreciate it in full. Keep
up the good work...

Nice one Pete - I thought you couldn't get the ATIK to work on you PC, or
was that only with K3CCDTools ?

Cheers
Ian.

It was K3CCDTools glitching on my laptop, When this happened, I was
unable to call up the video properties of the camera - a little
fundamental! An older version of K3CCDTools seems to have done the
trick.

It's big now but still too contrasty IMO.

Now I see it. My best guess is that you need to change hystogram
stretching as you're clipping the highlights leaving much in a too
uniform graytone. You have already overexposed few parts so why wasting
mid-tones with these areas?

I think I'll do it properly next time ;-) To be honest, I didn't
intend to do the whole terminator as the moon was low above some
neighbouring trees to begin with. Working out from the centre,
obsession soon took over as usual. Next time, I'll do the whole thing
exposing for the bright areas properly.

Don't mention overexposure, you'll be bringing Norbert down on me ;-)

I've looked at your picture, Pete, and there is no overexposed area
But Andrea is right : you can adjust the histogram to get a lighter
picture, especially near the terminator.

Whatever, it's really a nice picture with a lot of details here. This
ATK seems to be a very good camera.
How many frames are there in this mosaic ?

I see that the image is now back to its former state. Indeed the right
topmost corner was overexposed, for what I could see. Pete can confirm
or deny if my guess is accurate.
