The distance from the camera to the feeder is about 35 feet. I've used extenders but still cannot focus. Any suggestions. Thanks Post Extras:       scopethis Postmaster Reged: 05/30/08 Loc: Kingman, Ks Re: ST 80 Focus question [Re: hdolan]       #2514333 - 07/12/08 08:10 AM Edit   Reply   Quote Quick Reply   I do believe that the extender will increase your focal length; thus you'll have to move the camera/scope further away from the feeders.
