This premium combined Cheshire Collimator with Sight Tube is manufactured for us here in the UK to a very high standard. Beautifully machined and anodised with a clearly etched cross on the target face and a precisely centred wire reticle.
The sighting tube’s narrow field of view and crosshairs provide a centring reference for the telescope’s optical elements. The Cheshire eyepiece has a means of providing illumination to a target face (set at 45 degrees to the illuminating hole) that will be used to collimate the primary mirror.

This is a very well built bit of equipment and has style as well as functionality. I have used it. My telescope required a bit of tweaking to be spot on. Images so far are crisp and clear so I am assuming it did it's job.
I would have given 5 stars if it came with even a tiny bit of info as to how to use it!!! Instruction leaflet please!!! Other than that - would highly recommend.

Built like a tank but it's just so delicate. The Cheshire is in a high quality all metal housing ,has just the right length to see what you need, and also might survive an asteroid impact!

Very well made!
My first Cheshire - and I'm glad I researched them.

I'll straight away admit that this is my first Cheshire Collimator, so I can't say I have any experience of any others.
I did research them however, and I noted that this "premium" model has a stepless barrel, so could be inserted over a wide range of lengths. This made it easy to regulate the space around my primary and secondary mirrors, to aid in their initial centering, (on my 10" Dobsonian).
The eventual view through the pinhole opening showing everything centred was very reassuring.
(Secondary edge, primary clips, primary centre spot, and Cheshire target hole).
Precise and built like a tank

Great product, so well built and dead centre. It is quite a bit more accurate than the cheap laser ones
in fact the FLO’s own range of precision machines accessories are all brilliant

The basic Cheshire is fine but this is definite improvement on that. With this Premium Cheshire the spot that you are centering is tighter and better defined as is the cross that helps you to centre the secondary. On a relatively fast scope both these features have improved collimation. Nicely machined and looks great too.

Collimate your reflector telescope easily with the cheshire Eyepiece just pop it into the drawtube and use the collimating screws on primary mirror to bring the centre of primary mirror onto the centre of crosshairs ,simple to use would recommend .

I read a review, that "no instructions were supplied" true but none are needed to use this Brilliant All in One Cheshire Collimator. It's your 'familiar' Telescope instructions you may need refer too "How To" set your primary Mirror Etc.
Simple, Cheap and Effective

Never am I to return to use laser collimators again. Equipped with a 2" Concenter sight tube and one of these premium Cheshire collimating eyepiece is all you need.
