Collimation is the process by which an instrument’s optical components are brought into precise alignment with its optical axis and mechanical axis. All mirrors and lenses should be centered and angled so that light entering the telescope forms a sharp image precisely in the center of the eyepiece.

Polished 45° Degree Flat
A Cheshire eyepiece has a polished flat set in the barrel at a 45° angle, which directs light entering from a cutout in the side of the barrel down into the optical path.
-
Steel Crosshairs
The cross-hair adopts strong and durable steel wire instead of easily broken copper wire or aluminum wire.

It's too short to work easily. The longer version of the cheshire collimation tool would be better as you have longer eye relief for seeing the cross hairs on the collimation tool. I dont recommend this short version, get the long version and save yourself the headaches.

From what I could find on line, this product does not work well with SCT's. Videos show that it would work pretty well with Newtonian's The advertisement says it works with SCT's but doesn't. If it does. They should make a video to show how it's done.On the plus side. It is made pretty well.

You stick the laser into this and stick the whole thing into your telescope's focuser. Makes it very easy to collimate the telescope. Works on any Newtonian type telescope with a 1 1/4" focuser, or a 2" focuser if you have a 1 1/4" adapter.

On the money vanes a little hard to see but right on the mark I always use three different ones to check the alignment of my Orian Telescopes both 12 & 6 inch, the lasers were a head ack tried three different brands.old school is the only way to go....

I use this to double check the collimation that I perform with my laser collimator, but it would work equally well to collimate your telescope on its own. The quality seems to be very good, with good materials (metal) throughout. After doing a laser collimation with a known-good laser collimator, it correctly confirmed that the telescope was properly collimated (this really just takes a few seconds to do this confirmation).I give this 5 stars because it is a useful, well-made device at a good price.

These are simple tools requiring only that they be built solid and that the pin hole be well centered etc. This one is about half the price of others I've seen and seems well made. It looks and works like any other brand's I've collimated with, so no issue giving it 5 stars.

Works as good as a Laser collimator maybe better . My newtonian is way sharper

A Cheshire collimator is dead simple: It's a tube with a tiny, centered hole on one end, and crosshairs on the other, with a cutout so that light from the outside is reflected on the 'mirror' surface near the eyehole.It is easy to collimate a reflecting telescope's mirrors with one, because you just line up the mirrors so they are all dead center* (mostly, more on that below) and "Voila!" - a collimated telescope that will show sharper images at the eyepiece.This one by Tydeux feels pretty substantial, and has all the elements to make it useful. I included a photo of how a collimated telescope should look with the crosshairs of the Cheshire at a 45 degree angle to the secondary mirror support-spider.* Note that in faster telescopes (f6 and faster) the secondary mirror does get offset somewhat so that the early portion of the light cone coming up from the primary mirror hits that area first and doesn't get missed - note the offset in my wife's f/5 reflector photo. That telescope is collimated - but the secondary mirror appears "off" because the section closer to the eyepiece/focuser is offset that way.Overall? This works and the price is right.
