Fantastic image once again.

Thanks Mark.

The 16803 has deep wells - 100,000 electrons. That helps. Not too long a sub probably helps. But the main thing I would say, most likely, is the excellent baffling in the AP140 scope.

Also, I did angle the frame a tad to remove a stray reflection coming from one of the other Orion bright stars top left that virtually disappeared when it was angled just a little bit. So those baffles worked really well.
I did not do any special processing on Alnitak. That is how it came out of the camera pretty much.

Greg.
