ZWO Adapter D70-M54F: the OAG-L without filter wheel
Are you using the ZWO OAG-L off-axis guider without an electronic filter wheel? Then the optical train is missing precisely the thickness of that wheel. This adapter fills that gap: it mounts via the M54 thread to the OAG-L and keeps the backfocus with cooled ZWO cameras exactly at the standard 55 mm.
With a 15 mm height and an integrated filter thread for 2-inch filters, you can combine guiding and a single filter, without a filter wheel and without doing math for extension rings.
Features
- Exact 55 mm back focus with OAG-L and cooled camera
- Integrated thread for 2-inch filters
- Only 15 mm high
- Direct M54 connection to the OAG-L
Compatibility
For the ZWO OAG-L in combination with full-frame and APS-C ZWO cameras, in setups without an EFW filter wheel.
