About this product

Astrodymium Fine Adjustment Spacer Rings M42

These rings slip over the thread of an adapter/extension tube and are primarily used for fine tuning backfocus for astrophotography, but they can be used for other purposes as well.

The M42 set comes with 16 individual spacer rings. 4 of each thickness is included: 0.4/0.6/0.8/1.0 mm.

The width of the rings is 3.95 mm, and the inner diameter is 0.5mm larger than the specified size, for good clearance on the threads (They will not get stuck and are easy to insert or remove). 

Made out of UV resistant PETG plastic that can handle up to 80C (176F) temperatures without deformation.
