Omegon 2 inch to 1.25 inch Twist-Lock Adapter: clamps with a twist instead of a screw
The standard adapter clamps your eyepiece with a screw-type fastener: the eyepiece tilts slightly and the housing gets a dent. This twist-lock system is different. A turn of the ring locks a self-centering clamp that holds the eyepiece firmly in place all around and precisely centered.
You notice that at high magnification, where a tilting ocular distorts the image to an off-center view, and when switching in the dark: turning is possible with gloves on, but finding a screw is not possible.



Self-centering and damage-free
The clamping ring presses evenly around the casing. The eyepiece therefore always remains on the optical axis and does not leave any dents or scratches.
Filter wire built in
At the bottom is a 2-inch filter thread. A moon filter or light pollution filter rotates in it and then works for each 1.25-inch eyepiece you attach to it, without moving the filter per eyepiece.
Featured accessories
For telescopes with a 2 inch focal length and 1.25 inch eyepieces and accessories. All standard 2 inch filters fit into the filter thread.
For whom yes and for whom no
- ✓ Observers who often change eyepieces
- ✓ Who wants exactly centered eyepieces at high magnification
- ✓ Anyone who works in the dark with gloves on
- ✗ Who never uses 1.25 inch accessories
- ✗ Configurations with extremely tight back focus: the adapter adds approximately 30 mm
