Eyepiece holders

Eyepiece holders allow you to connect instruments with 31.8mm or 50.8mm diameter barrel to other accessories. Usually the accessories inserted are fixed with one or more screws. Our OnAxisLock is the locking system for accessories that, compared to the classic screws locking system, offers the following advantages:

- more clamping force avoiding any possible flexure (then it's perfect for astrophotography)
- it does not damage the connected accessory
- it perfectly center the optical axis of the telescope

All this thanks to a new locking device with double ring: just rotate manually the appropriate outer ring (designed to allow an easy grip, even with gloves) in order to obtain a perfect closure!
