Review: Worked to collimate an RC telescope - Maybe this is not recommended to collimate a RC telescope, but it worked for me and with the simple design there is nothing needed to check the accuracy of this eyepiece.
Review: Very easy to use - Very well made. I bought this to have one more way to collimate our telescope. I tested collimation with the ring around a star and with the cheshire and had the same results.

## Questions & Answers

**Q: What type of battery goes in this?**
A: There's no battery for this. No moving parts and no electronics.

**Q: Do refractor telescopes need collimating ?**
A: No refractors do not need collimation

**Q: Will this work on a Bushnell North Star? I believe it is a 3.5 maksutov type.**
A: No it will not work as your scope is a Mak-Cass type of scope... You have a cover plate  on the front glass aperture, your collimation is corrected using the screws located under the corrector plate. You have to do a slightly off focus star adjustment, the star should look like a concentric set of rings within each other when collimated properly.http://uncle-rods.blogspot.com/2009/07/zen-and-art-of-telescope-collimation.html

**Q: Will this work on Celestron PowerSeeker 114EQ?**
A: Hi!  The Collimation Eyepiece will work for your telescope.  Your telescope takes 1.25 inch eyepieces which the collimation Eyepiece is made for.

### ⭐⭐⭐⭐⭐ Worked to collimate an RC telescope
*by R***B on April 10, 2026*

Maybe this is not recommended to collimate a RC telescope, but it worked for me and with the simple design there is nothing needed to check the accuracy of this eyepiece.

### ⭐⭐⭐⭐⭐ Very easy to use

Very well made. I bought this to have one more way to collimate our telescope. I tested collimation with the ring around a star and with the cheshire and had the same results.

### ⭐⭐⭐⭐⭐ Most Precise Tool for Collimating a Newtonian or Dobsonian Telescope!
*by T***S on December 29, 2014*

If you have a Newtonian or Dobsonian telescope, you can purchase all manner of complex thingy me do's to align your primary and secondary mirrors, (many of which often work poorly) or you can just buy this combo tool for a great deal less. This eyepiece is a both a sight tube and a Cheshire eyepiece rolled into one. You then simply align your secondary mirror under the sight tube and then align the crosshairs reflection on the primary with the crosshairs at the bottom of the sight tube and bang, you are done. If you have never done a collimation before it might take up to ten minutes the first go, but after that, it takes less than two minutes. Absolutely essential tool that just flat out works. Five stars.
