We have way more people here that are highly knowledgeable on optics than all the archery sites. Sometimes I think it's the mind set of it has always been like this..... Why can't a fixed power (or maybe a 2-6 power) long eye relief adjustable parallax and diopter be built? I know a custom mount will have to be built to allow for alignment through the yardage range. Which for indoor shooters your at 20 yards and just micro adjust. I'm tired of fighting clarifiers (lens in the peep) and the lenses in the scope. 20 ish years ago I used to shoot with an old guy that had some eye issue that be could not see the pins. He built a custom mount and used an oddball scope. With the optical technology so much better now I'm failing to see why this isn't something that has been worked on.
