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?:confuse2:

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.:scared: 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):P .

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!:D
