Hi Guys,

I was wondering if there is a way to show C-scope with a throw of 14 feet? All the attachments I've seen have an marking of 17 feet. But seems that you can focus past that marking.

Your answers can be found a few days back on this forum under the thread titled "good results with scope image at 12'? "

Hi

I am presently running a Devry XD with a German made ISCO Kollmorgen KA298 anamorphic lens at 15 ft with excellent results. The closest barrel marking is 5 meters or a little less then 17 ft but will still focus closer.

I ran a test film with resolution targets and found I could go to 12 ft and still get excellent sharpness. The 12 ft distance was about it. Any closer and the image lost sharpness.

I purchased the KA298 for about $100 on Ebay.
