I'll need to do a bit more research on the subject but from inserting my 2" laser colimator that I use to climate my newts, the laser appears pretty much dead centre. I'll need to measure it properly (as much as you can with a ruler
) but it looks pretty good to me.
The image was pretty well focused with a mask, I would imagine that an out of focus image would mute the effects of poor colimation.
Also I'm pretty sure I have the distance between the camera chip and the flatter correct as the images have a pretty flat field.
I'll post some results tonight from ccd inspector. I just purchased it last week and haven't delved into it to deeply as it looks like a steep learning curve.
Thanks guys.
