Skywatcher

This collimating eyepiece is a combination of a sighting tube and Cheshire eyepiece. The sighting tube’s narrow field of view and crosshairs provide a centering 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.

Just Brilliant

Simplicity in itself, there is no instructions BUT there is plenty of info online about how to use one, id been using an home made colli cap from the tube end, needless to say, this smoked it in every single way lol, Cheers FLO.

Brilliant little tool for perfect collimation.
Wednesday, 14 May 2014  | 

Firslty, what absolutely brilliant service! My product was delivered just one day after I ordered it; I am very impressed.

This Cheshire eyepiece is excellent, and although I do think it should be supplied with instructions, I did manage to get perfect collimation in less that ten mins! I confirmed the collimation with a star test (looking at Polaris during good seeing) and was greeted by perfect circles.

Clear and dark skies!

Item is well made, however it comes with no instructions what-so-ever. For someone who has an idea of how to use one of these it's not a problem, but for the beginner being advised to get a cheshire collimator it will leave them asking what on earth they do with it.

Fortunately using a cheshire is well documented on the forums and other websites....

SW collimation eyepiece

This is a good quality collimation eyepiece. Easy to use, but would benefit people new to collimation if instructions were included. Well made and will last a life time.

Nothing to be scared of
Tuesday, 31 May 2011  | 

Being new to astronomy the idea of collimating my scope did scare me a bit, but with this eyepiece it was easy! The only thing I find slightly disappointing is the price. Essentially this is just a tube with a few holes in it and a couple of wires, so I think 25 is a bit on the pricey side. On the other hand it is much cheaper than its laser counterparts, so maybe its not that expensive.

Easy to use and does the job well.
