See all your telescope is capable of delivering with the Celestron collimation tool.
The optical performance of most Newtonian telescopes can be optimized by collimating, or realigning, the telescope's optics, as needed. This procedure is easily accomplished with Celestron's collimation tool, a handy accessory that comes with detailed instructions. It makes short work out of what was once a laborious chore.
The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1¼" focusers or diagonals.
Alignment is easy using the small opening on one end and thin cross hairs at the other end. The collimation eyepiece is more accurate than the simple Collimation Tool.

This is a tool no one should be without. As a secondary collimation tool used to test accuracy of laser collimators and as a primary for those who are not concerned with the fine tuned focus a laser provides. It covers all three aspects of collimation. The one report of it not being useful for secondary collimation is not accurate. It just takes some patients and a little practice.
The only reason I don't give it 5 stars is I would like it to be a little tighter fit in the EP barrel. I find that it wobbles a little. To get the most accurate result I let the sight tube go all the way in so that it is flush with the focuser. Then use the focus to extend the tool the proper distance from the secondary.

I used it to collimate my Zhumell Z10, this simple collimator is not as easy as a good laser, but it worked eventually, just took much longer time. On the other hand, I don't need to worry about the danger assoicated with a laster collimator, that is certainly an advantage.

Comments about Celestron Specialty Collimation Telescope Eyepiece Tool:
I've been using a similar collimation eyepiece I bought for a pittance, but realized it was itself not well aligned (the intersection of its crosshairs did not remain fixed if I rotated the eyepiece in the sight tube). The new eyepiece has clearer crosshairs, and they appear to be dead-on (intersection not affected by rotation). The instructions are clear, though as everyone says, it takes a little while to get your head into what you are seeing). I found that whereas my secondary mirror appeared to be well centered both from looking into the focussing tube without an eyepiece, and with my former collimation eyepiece, it was immediately apparent with the new one that the secondary mirror needed to be repositioned along the tube axis. So I'm a happy camper.

Comments about Celestron Specialty Collimation Telescope Eyepiece Tool:
This could not be used to collimate my astromaster 130, because the eyepiece does not sit square with the OTA, causing a distorted image. Celestron tried to help, but I went through
two OTAs and two eyepieces with the same result. I can only hope the out-of-box collimation is good and that I can also do nighttime collimation.

Comments about Celestron Specialty Collimation Telescope Eyepiece Tool:
When I purchased this I did not expect too much. I read up on the subject, and knew what I was purchasing. This is a simple tool for helping to align the mirrors of a telescope, nothing more, nothing less, and it does that just fine. There are no lasers for alignment, or even any real optics, but it works.

Comments about Celestron Specialty Collimation Telescope Eyepiece Tool:
So I had a mishap with my C-8 that required a re-alignment of my telescops mirrors. Took me 20 minutes for a first attempt. The instructions that came with the tool were clear and consise and figuring out how to make the dots and circles move was a snap. If you need a collimation tool and you're not sure if you need all the bells and whistles of the laser devices, this is the tool to get.
