This is a Must Have and a Total Pleasure to make switching eyepieces better than eating your favorite cake. So much better than tweaking set screws.. Quick, precise and worth every penny. It will make your scope "Deluxe"...and if you use a laser collumnator like I do...than its necessity for a sure alignment.

This gives precise, REPEATABLE centering of your collimator. I have previously purchased another self- centering collimator from another company but returned it as it did not give repeatable results and was more expensive. I've been an Orion customer for 10 years and will continue to be! Bravo Orion!

I got this for use with a Celestron collimation tool (cheshire and sight tube). I do like it better than the standard 2" to 1.25" adapter, but for collimation there is a design flaw. Inside there is a strip of rubber that constricts or loosens when you turn it to tighten or loosen. I assume this is to prevent metal-on- metal contact so eyepieces and such don't get marred. However, at the standard 1.25" size, there is a gap in the rubber (between the two ends of the strip). Thus if you tilt the eyepiece or collimation tool, etc it can wobble into that gap. If the strip of rubber were a tad longer this wobble could be eliminated. With a little guesswork, I believe I was able to find the right tilt for collimation, but for the price, I was hoping for more precision than this provides.

I wish I had got this sooner. It had always bothered me when I was collimating that when I tightened the laser or the cheshire that they'd move. And never in the same way. Those days are over. Every time I check my collimation upon putting my telescope together I'm assured that whatever I'm using to check collimation will be dead center in the focuser. Twisting the laser around does not change where it's aimed. I've seen other adapters simular to Orion's but not only were they more than twice the price I saw nothing with them to justify that cost. Orion's adapter is well engineered and well worth the small price for the peace of mind it gives me.

The precision centering device does the job for me. I insert my laser collimater into the device, tighten the ring and then I can collimate with no wobble.......

I bought it specifically for the laser collimator (which, I found, was too wobbly in the eye-piece to be of ANY use for collimating). Turns out the two should be bundled together. Because of that I give the eyepiece adapter 5 stars, and the laser collimator 2 stars.

I thought my scope was well collimated till I inserted this "lock in" device. I was off a fair amount. This is worth getting.

I bought the Lasermate Deluxe Collimator with my XT8 Intelliscope about 9 months ago and was disappointed to find that because the Lasermate was ending-up positioned off- center when in the 1.25" focuser adapter and the thumbscrew tightened, I couldn't get anything remotely approaching accurate collimation, and have instead been using the standard Collimation Cap supplied with the telescope. Until I bought the Orion Precision Centering Adapter (PCA) that is! I removed the standard 1.25" adapter and replaced it with the PCA. Now the Lasermate sits perfectly centered and I was able to perfectly collimate the telescope. In fact, using the Lasermate with the PCA, I even found that my secondary mirror has been out of alignment all this time. But it's aligned correctly now! Now I have sharper, clearer views of the stars and planets. All thanks to this little adapter! The PCA is an absolute MUST if you own the Lasermate Deluxe. In fact, I think all telescopes should come with this focuser adapter instead of the standard one, because using it with an eyepiece means the eyepiece is also perfectly centered and therefore you'll know you're getting the most precision and performance possible from your telescope. One important tip I found was to make sure the PCA is fully tightened around the Lasermate when collimating. This will ensure the unit is perfectly centered and that there is no 'play' possible in its position. Once I did this, the Lasermate collimation process worked perfectly and I was very pleased (and somewhat relieved) to find that everything was also perfectly aligned when I checked it through the standard Collimation Cap peephole afterwards. The Lasermate is so much easier to use than the standard Collimation Cap for quick collimations out in the field. Finally I can use my Lasermate Deluxe for its intended purpose, instead of just using it to play with the cat! I am so grateful to Orion for making this adapter! Thank you!

What can I say about this? It's just a great item to have. If you have a 2" focuser, get one of these. It does just what it says it does. I like the twist ring to lock and unlock the Eyepiece. No more having to mess around with a small thumb screw to insert and remove an eyepiece. I still don't quite understand how it gets the eyepiece centered, when you insert the adaptor in your focuser you would think it would be off when you tighten the screw to lock in this adaptor. But, it doesn't seem to make a difference. My cheshire collimating eyepiece shows dead on alignment. Every 2" focuser should have one of these from the start. It's a great adaptor, well made and does just what it says. Nice job guys! Great product I recommend it very highly.

When I got my new telescope with a 2" focuser, it came with a 2"-1.25" adapter which uses a compression ring to 'center' the eye piece. All the compression ring succeeded in doing is grabbing onto my EP's when I tried to pull them out, or get in the way of my EP's when I try to put a new one which would then jar the telescope and I'd loose my target. Oh, and the compression ring didn't center it any better than the standard 2 thumbscrews would. This product should become the standard EP holder on all scopes, not just as an adapter. It doesn't grab onto my EP's and the movement is very smooth. This is an amazing product and a must have for anyone needing a 2" to 1.25" adapter. When Orion offers a dual speed focuser with this as it's primary way of holding the EP's, I'll be one of the first in line to get it!

This is the product I've been waiting for. I own a 16" Lightbridge and a Meade collimator. No matter what I tried the collimator always jiggled inside the focuser. I even spent a lot of $ on a JMI focuser, same result. I gave up and parked the Lightbridge. Now with this product I get solid collimation easily.

Reviewer: Kent Blackwell

I've been waiting years for such a well- made and welcomed accessory to come along, and leave it to Orion Telescopes to offer it at a bargain-basement price. I know of no one else producing such a device, at any price! Once I collimate my telescope using a Chesshire or laser collimator I can be assured the actual viewing eyepiece will be positioned precisely the same as the collimator. Additonally, the Precision Centering Adaptor holds the eyepiece safely and snugly in the focuser.
