Highlights
Filters inevitably collect dust. They may also need to be inspected, repositioned, replaced, or temporarily removed as your imaging requirements change.
With most electronic filter wheels, reaching the filters means removing the camera or off-axis guider, disconnecting adapters, disturbing cable routing, or opening the wheel’s entire outer cover. On some imaging trains, the cover screws are blocked by equipment attached directly to the wheel.
The OGMA OFW52EZ solves this problem with a dedicated filter-access cap.
Your camera, OAG, adapters, and filter wheel can remain connected. Camera orientation, optical spacing, and cable routing remain undisturbed while you service the filters.
Only the access area is opened rather than exposing the complete interior of the filter wheel.
