File types for stacking

[baggywrinkle]

What file types are best for stacking withn Registax, I have tried 16bit TIFF but it then tell me it is out of memory.

Should I used 8 bit or some other format?

I always convert my RAW frames to 16-TIFFs before feeding them to Reg 5.1 ( can't get on with V6 personally)

Never had a problem memory-wise , even when opening 300+ frames to preview or stacking 150+

Sounds more like a computer shortcoming to me .

My version is V6

You would be better off using DSS if you are stacking DSO pics from your canons.

What type of images are you attempting to stack? What camera are you using for the captures?

Cheers,

I tried Deep Sky Stacker using both RAW and TIFF files from my Canon 650D.

Individualy the images are correct and show stars (sharp too thanks to using Backyard EOS focussing), but when stack they seem to come out as a negative, so the image appears mostly white.

Have you tried adjusting levels/curves on the image from DSS? Sounds like these are DSO images, so DSS is the prog to use, you do need to adjust the image it outputs though. A quick search will find plenty of DSS tutorials.

Cracked it, the images do come out light but they need processing...doh!

I also found a good vidoe on the net which helped me through the process.
