Psychodelic Dark Frames???

Guys,

I probably have a minor setting wrong somewhere in Registax, but I've taken a few days to play and think it over, and still the light hasn't switched on for me.

Have you seen this before and if so what causes it?

This is an image of M45, about 4.4 sec exposure, captured on a ToUcam. About 11 images stacked. Darkframe was taken and save as a BMP and used when stacking.

If I stack it without a dark frame, the colours are OK, it's just got a few hot pixels in it as you would expect. When I stack it with a dark frame, this is the result.

All the avi's I captured on my first night playing wit the long exposure mod behave the same way. BTW I also gte an error message when I try to go to the wavelets page. I haven't come across this before when I've stacked images from my C5060...

Thanks,

Al.

Just in case anyone comes across this problem as well...

I have just down loaded Iris and started playing with it (try to learn how to drive it)

.

I happened to read in some of the documentation that when saving files as a TIFF file if any pixel values are negative, the TIFF format doesn't cope with this well. I haven't confirmed this yet, but I'll have a play, and post a reply. I think this could be the problem!
