This is a custom made focuser for an Astro-Telescopes 6" f/5.9 Achromat. It is unbranded but clearly a standard generic Synta/Orion/GSO 2-speed crayford focuser. It works well but has some wear and tear I will document below. It does have 1 unique feature in that the flange is male threaded to 86.5mm, so not the standard refractor attachment, it needs to thread onto a female barrel or adapter. It is a standard GSO style flange though so if this flange won't work for you, you can pick up a GSO 86.5 or 96.6mm refractor flange (~$30) and it will work perfectly with this unit.

Condition: Lots of wear and tear on the drawtube mainly, the body is fairly clean. Drawtube has bearing rollers marks on both sides, I sharpied them so it isn't so obvious. There are some dents and dings on the front and rear of the drawtube where the drawtube was dropped after focusing without the rear flange attached. Focuser still works great, I used it for imaging with an autofocuser (Sesto Senso) and I got some awesome images. There is some sag at full extension, just like any other crayford.

Message me with any questions, price includes shipping to lower 48 and PayPal fees.
