• Front side - 2" inner diamater
• Rear side M53x1 male thread and M48x0.75 female thread

Machined of high quality aluminium alloy.

This adapter allows using some focusers on 2 inch telescope diagoals.

M53x1 thread corresponds to focusers of an older model Vixen brand telescopes.

30mm depth of the adapter may be a bit too short for some 2" tubes, but this will reduce optical path on shorter tubes.

M48x0.75 female thread allows installing a 2" astronomy filter if necessary.
