Sorry - missing in action for a while.
Yes , 64 bit windows.
Are you trying to run imaging hardware at the same time?

I just ran two simultaneous 64bit instances where each was running a very large preprocessing drizzle stack on an I7 computer with 32gigs of RAM and it ran fine.

Re: Abell 426 from last night

Here's an updated image that's been drizzle stacked, with 3 more 1200sec images. Same processing as above but with 50 x ME deconvolution iterations:

AllCometEls.txt vs CometEls.txt

I guess the Minor planet Center must have renamed the comets file at some point. Anyways I have to remove the 'All' from the AllCometEls.txt file to get AA8 to read it.

It looks like the distortions from F5 and from F7 are too different, even for that option. May you post the two separate images?
Fabio.

I posted the separate stacked images here:

Stacking 10in F7 and F5 images

Two 10in SCTs F5 and F7!

This image is a stack of 10 x 1200sec subs at F7 and 14 x 900sec subs at F5. I used the 'Distorsions between images' option. No flats or dark frames (how?) Both OTAs were using an Orion SSpro camera:

Re: NGC 891 from last night - 2nd mount and camera

This image stack was taken at the same time as the first image. Another NGC 891 with an Orion SSpro APSC OSC (6mp 7.8m pixels) CCD camera through a 10in F10 OTA ,on a CEM120, using a Starizona .63x SCT reducer for F7 (~1750mm); guided off axis. I used a 2X drizzle stack, 20 x LR deconvolution and DD...
