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.

Fantastic piece of kit. The engraved cross hair on the 45 degree face is a genius addition as it allows you to judge when the dot is bang in the middle of the donut.

Robust and accurate

It's sturdy and precise.

Some criticism about lasers, but have to say I use this Cheshire collimator in combination with my AstroEssentials laser I received from FLO and I am getting close to perfect results.

The Cheshire does a splendid job of aligning the secondary under the focuser, and the laser is superb especially at aligning the primary as my telescope's focal length is too long to adjust the primary while simultaneously looking through the focuser. I finish everything off with a quick peek through a collimation cap and I am always pleased with the results.

The important things to ensure are that the laser itself is collimated, both the Cheshire and laser sit flush in the focuser, and that the telescope tube is not horizontal as that can tip the primary mirror forward and as soon as you point the telescope upright, collimation is lost.

There isn't any instructions with it but I don't think there usually is, even with lasers.

The service from FLO is always A1

5 Stars from me!

Excellent product- but the price.

This really is a pleasure to use and an essential kit for Newtonian owners. I have played with many other Cheshire variants but none come close to this. The only downside is a fairly aggressive price point for what is a very basic manufacture. I would certainly buy it again but my hip pocket nerve did feel the pain.

Great service again from FLO, thank you.

This piece of equipment looks good, feels rugged and works very well.
I've never collimated a telescope before - and no instructions are provided of note, however 20 mins of online research / watching a couple of youtube videos made it straightforward.

Works well enough if you know how to use it
Thursday, 30 July 2020  | 

Theres no instructions with this, look on you tube and you'll see plenty on laser collumator but not too much if anything on this if you know how to use one of these, great if you are a newby like myself its guess work. Comes in a plastic bag without any protection caps for the ends. its a nice red anodized colour but i don't think you could call it premium. There are simular items at half the price, end cap protection and instructions elsewhere. The only time i've been dissapointed with flo's description of a product.

Quality!!
Monday, 29 June 2020  | 

Amazingly made this cheshire. I'm a Newton user and need to fix the telescope and later on it must be collimated of course. Since I want to get the maximum out of this telescope I decided to go for a precision instrument. And so I was directed to this beautiful piece of equipment. I'll be doing my first collimation ever and therefore I wanted quality. Well, it is!

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.
