Review: EASY 2 USE - THANKS GREAT ITEM
Review: Must-Have Alignment Tool - Using this collimator to align the mirrors in a reflector scope is a must-have item. After the procedure, images are crisp and clear across the field of view, even with my relatively small (3" F9) Celstron reflector. Frankly the instructions for me especially as a first time user are not easily understood, especially in discerning between various images seen through the eyepiece. I researched "collimation" on the web, and pieced together sufficient info to understand all the images fairly well. Also placed a small, stick-on center dot on the main mirror for convenience during alignment. Definitely recommend this eyepiece - quality built for the money - it will be used periodically to keep the scope in tune, and it can be used as one graduates to larger reflector scopes. I never tried a laser collimator, but with the excellent results from this piece, not sure that a laser is necessary, at least with an F9 scope - perhaps it might make a difference on an F5 or lower, just guessing.

## 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.

### ⭐⭐⭐⭐ Great Product, poor directions for use.
*by K***. on March 11, 2014*

I purchased this to help with the collimation of a few telescopes I have, thought it would improve the process. Was hoping to be able to take this out of the package and with a few directions it would be a simple task. Unfortunately the directions were a little hard to follow for the first timer that I felt like I was. After finding some internet help, I was able to Collimate my scopes and the tool does make it a simple process. I shared this with some of my friends who have experience in this. They found the eyepiece to be very helpful. If you know what you are doing it is out of the box great, if you are a novice like myself it takes a little playing. While I ultimately managed to complete the process, it was a little frustrating at first. If you are planning on transporting your scope regularly, I would recommend this tool. When finally completed, it did a great job.
