gobos in a 90 deg lens

does anyone have a formula to fix the distortion a gobo will have in a 90 deg lens? the fixture is going to be about 10 feet away from the screen.

Given exact and accurate information, Apollo can provide keystone correction; so I bet they could compensate for pincushion distortion as well. I suspect other custom gobo makers can do this also.

Thanks Derek for the heads-up regarding this gobo question!

I spoke with Kenny (an artist working for Apollo for 16 years) and he stated that the formula used is accurate when manipulating the 'pinchion distortion' Derek aptly described. If you do plan to have a custom gobo made using the 90* lens tube, please let Kenny apply his magic and we'll get it looking good for you.

Derek, thanks again.
