Lacerta OCTO focuser for refractors (guided on 8 pcs bearing, with 1:10 microfocus, M54 thread, 2" eyepiece-holder)

The Octo eyepiece extension series is being expanded further.

We now also have a rotating extension for refractors with 95mm adjustment range and 2 inches (50.8mm) free opening.

All 8 ball bearings can be adjusted independently of one another so that the extension tube runs optimally.

More about the product

Low profile "Bearing Type" focuser with 8 ball bearings (for Newton)
At these very high loading capacity extracts, is the storage of the extension tube with eight ball bearings. The drive is available with Crayford shaft or with a classic rack, the latter principle has prevailed in the short excerpts built because the brake screw can be placed at the side and at the terminals there is no tipping. The Lacerta Newton extract with extra low profile works in this manner, we recommend it for high loads. 

Ball-bearing "Bearing Type Linear" statements for SC
In this type, the extension tube is attached to the bottom rail on both sides out of two oversized ball bearings and held. Characterized in that the tube is supported only at the bottom or out, the construction can be carried out much more easily than a comparable Crayford focuser. The weight of the 2.7-inch refractors for linear statement is as about 30% lower than similar sized Crayford constructions. Eyepiece has the 2.7-inch refractor for linear pull a M74 external thread and a rotator with this, the connected equipment or the camera can be rotated smoothly and effortlessly into the desired position.
