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. A reflective target face (set at 45 degrees to the illuminating hole) makes it easier to collimate the primary mirror.

I tried a laser collimator and it made the telescope even worse. I bought this one and it was a lot better. The only problem is, you don't get any instructions with it. Being a beginner and not sure what to do, I had to drop an email to them for some instructions. It's taking a bit of getting used to, but I'm getting there. I'd give it 5 stars if it came with instructions.

Basic but accurate, no faffing about collimating the collimator like with lasers, it just works. One slight improvement would be to remove the step in the tube and make it 1.25" all the way.

This is a high quality collimating tool I had to use it ones. The build quality is first class, the only thing I would say it would be nice, if it had a manual with it, as It was my first time using one. It came very quickly from FLO, so thanks.
Well made, but can i have some instructions please?

I bought this over the seemingly more complex laser collimator. My only issue is that I have no instructions on how to use it, (I am finding that this is a common theme with Astro gear) All bar one of the Youtube demos I have managed to find show how to use a laser collimator, I struggled to find a video demoing the use of the Cheshire collimator and that didn't explain it well enough for me to understand. I thought it might have been more common. I have since bought a laser collimator so at least I can follow the myriad of explanatory videos out there. Operator error? perhaps!
Cheshire collimating eyepiece.

As as a complete beginner I contacted Flo for advice on alignment of my telescope. They were very prompt & very helpful with their replies, suggesting the Cheshire collimator. Having read a lot of their other customers reviews, I was happy these are trustworthy folks that don't pressure you for a sale. They kept me informed about despatch and delivery, which was really quick.
Highly recommended, will definitely be buying from them again.
Simple to use invaluable tool
