Product Description

PrimaLuceLab OnAxisLock 50.8mm Eyepiece Holder for 2.7" Hybrid-Drive Focusers

OnAxisLock 50.8mm eyepiece holder for 2,7" Hybrid-Drive focusers replaces the typical eyepiece holder in AIRY ED100 and APO120 apochromatic refractors focuser and lets you take advantage and use all the 50.8mm diameter accessories.

OnAxisLock is the accessories locking framework that, compared with those that use typical screws, offers superior clamping force avoiding flexure (so it's ideal for astro-imaging), it doesn't harm the connected accessories and perfectly centers the optical axis of the telescope. All credit goes to this new double-ring locking device: just turn manually the appropriate external ring (designed to allow an easy grip, even with gloves) in order to obtain a perfect closure!

Amid use of heavy imaging instruments such as DSLR or cooled CCD cameras (typically equipped with filter wheels), it's vital to avoid flexures when inserted into the telescope's focuser. This is likewise vital for visual use using large mirror diagonals and wide field eyepieces (which are often very heavy).

That is the reason PrimaLuceLab designed the OnAxisLock eyepiece holder that replaces the typical screw with a new locking ring mechanism. This allows you to perfectly bolt the inserted accessory just by turning the outer ring (red): an double ring tightens internal accessory with a uniform pressure. The OnAxisLock eyepiece holder additionally allows you to keep perfectly aligned the accessories inserted in the focuser: so you will be sure that your camera's sensor will be perfectly centered with the optical axis of the telescope.

In order to connect this model to Hybrid-Drive 2,7" focusers of AIRY ED100 and APO120 telescopes, simply unscrew the original 50,8mm eyepiece holder, then screw on the OnAxisLock.

This particular locking mechanism also prevents the harming of inserted accessories because the pressure is distributed uniformly in the barrel. With the classic screw closure the mechanical stress is instead brought on a small area and this can easily ruin the barrel.

The special design of the outer ring has been developed to allow you to lock the accessory with ease, even when wearing gloves. This way you can be sure to safely lock your CCD camera or your eyepiece even in case of bad weather conditions.
