Bias/Offset frames with a webcam

[cuivenion]

I am unsure how to create bias/offset frames with my PS3 Eye webcam, I'm assuming ISO translates to gain, but I'm unsure about exposure as frame rate also effects this. Should I choose the highest possible frame rate as well as the quickest exposure?

Bumpity.

Exposure and frame rate are linked aren't they? Eg 0.100 fps = 10s exposure.

[cuivenion]

So at that point I should use the fastest framerate and the fastest exposure when doing a bias frame?

[jimbo747]

Probably... Never done them myself! Only ever used darks with my mak.

I shall carry on googling in the hope of figuring it out then. I've got an image of the Ring Nebula to put up when I finish processing it. It's still not great but it's a lot better than my last DSO effort.

Can't wait to see it, I'm interested to see what can be done with that little camera. I'm just using mine for planetary and lunar work, got a cheap £70 1100d which has taken on the DSO duties now.
