About this product

Model:  Prem_Cheshire

The essential accessory for anyone owning a Newtonian telescope.

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.

My first Cheshire - and I'm glad I researched them.
Thursday, 6 September 2018  | 

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 FLOs own range of precision machines accessories are all brilliant

Premier Cheshire
Monday, 30 April 2018  | 

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 .

Instructions not needed

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.

Good for longer than about F5.5
Friday, 22 August 2014  | 

This is a nicely made bit of kit, BUT only for longer scopes. with my F5.0 scope you can't quite see the whole of the primary mirror through it.

Great bit of kit

Got one for Xmas due to frustration with laser collimators. Very easy to use and the cross on the mirror of the cheshire makes alignment very accurate.

Your Question:

Q1. I have a Celestron 114EQ short. This has a lens at the end of the focusing tube. I take it that to collimate this you would need to remove this lens?

Yes - this lens will need to be removed before collimation.
