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 M42 T-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 a T/T2 M42x0.75 male thread on the other side
- Not for use with the more common M68x1 threads used by Zeiss, Baader and others.
Features:
- Precision machined, black anodized aluminum
- Also features an M42x0.75 T/T2 female thread on the inside of the M48 thread so you can use this adapter with the M42 female thread on the camera side instead of the M48 male thread.
