Disable Overscan
Is there a way to disable overscan? I've been trying to use sharpcap along with the circle overlay to center my secondary but the overscan moves the apparent center of the image.

Re: Disable Overscan
Hi,
there is no way to disable overscan if the camera manufacturer has turned it on (I'm not aware of any brand that I support having controls to turn overscan on/off). However, you may be able to use a reduced resolution and set the ROI offset within the full sensor area to get a central view.
cheers,
Robin
PS. What camera model?

Re: Disable Overscan
I actually just took out a pair of calipers and my sensor is not centered. I've never noticed that... : ( why in the world would it be off center. Would that effect my guiding and polar alignment ?
its an ASI120mm usb 2.0 version. It's strictly used for guiding and polar alignment right now.

Hi,
exact centering is not important for guiding or polar alignment, so you are OK there. The only thing you will have a problem with is going to be collimation.
