I use a Nikon which outputs MOV movies, and I haven't got a program to convert as yet.
For this image:-

I used about 80% of 40 stills, stacked in Registax with a bit of wavelets and contrast and brightness adjustment in photoshop. That was it.
I used ISO200 at 1/640s.
Keep at it

I think that 2048x2048 frames ran okay in AS!2 but from memory, 2560x2560 frames had the top and bottom chopped off.

Hey Dennis an Bob,
A couple of questions after giving it a go with both Autostakkert and Registax.
At full res
5184 x 3456 both programs quickly die no matter what file format I convert the Canon CR2 to.
At 1960 x 1814 (cropping plus some downsampling)
TIFF
Registax: can't read them properly (all frames look like the moon on acid)
Autostakkert: Crashes importing files with "invalid floating point".
BMP
Autostakkert: Freezes on "analyse"
Registax: gives me a great looking small piece of the moon. One was a crater on the edge that looked absolutely stunning, almost 3D, but the other 97% of the moon - where my POI and/or align points were - just wasn't there. The same no matter what settings I use. It also sometimes freezes. (this is where I likely need to learn a lot more as well)
Downsampling another 50% with either BMP or TIFF gets me an image in Both programs, but I have had to downsample so much I have lost detail.
I assume formats and size (plus my knowledge) are getting in the way. I'm not asking for a tutorial on the programs, as that's my job to go and learn. Just wondering how you guys get around these issues with file types and size/resolution?
Do you shoot from the image at lower resolution?
Do you use some specific way of converting/downsampling that doesn't result in the image quality losses I was seeing?
Appreciate the help.
Thanks
Mick
