## Description

desertcart.com : Astromania 1.25" High Precision Double Helical Focuser with 0.05mm Scale for Telescope Lenses/Finder & Guidescope : Electronics

Review: Well engineered - Very precise and well machined focuser. I use it on my guide scope and it dials in the focus perfectly. Great price too!
Review: Crappy packing, durable focuser. - The terrible packing job done by desertcart is testament to the mechanical quality of the focuser. It's little box was put inside a long shoebox and it bounced around everywhere, destroying the box and tearing a hole along the outer box seam. I'm amazed it arrived intact. It's a bit tight and will need to be worked over a bit to loosen up, but otherwise it does what it says it does.

### ⭐⭐⭐⭐⭐ Great all around unit
*by R***Y on October 26, 2025*

This unit is just what I needed to achieve micro-adjustment focusing when taking pictures through my grab and go telescope, especially at night. The adjustment is very easy and smooth, eliminating a lot of wobble when fine tuning.
