Product Details
Description/Uses:
- Many (but not all - check your telescope or with the manufacturer) Explore Scientific and Bresser telescopes have a telescope drawtube in which the 2" eyepiece/diagonal holder (visual back) is threaded on to the focuser drawtube via an M68x0.75 thread. Removing the visual back on the scope exposes a male thread on the drawtube.
- This adapter allows you to directly attach M54x0.75 threaded cameras and accessories to the focuser drawtube for a direct and more secure connection.
- Features an M68x0.75 female thread on one side and an M54x0.75 male thread on the other side
- Not for use with the more common M68x1 threads used by Zeiss, Baader and others or with M54x1 threads used by Sky-Watcher and others.
Features:
- Precision machined, black anodized aluminum
- Also features an M48x0.75 female thread on the inside of the M54 thread so you can attach 2" astronomy filters on the M68 side or use this adapter with the M48 female thread on the camera side instead of the M54 male thread.
