Celestron 1.25" CrossAim Reticle Illuminated Eyepiece - 12.5mm # 93235
Does the job but doesn't impress
Bought this mostly for aligning a computerized mount and it serves its purpose. What I don't like are 1. the reticle focusing adjustment is always loose, 2. even at the lowest setting the lines are still too bright, 3. poor eye relief. This was my ...

Meade 1.25" Wireless Illuminated Reticle Astrometric Eyepiece - MA 12mm # 07069
Great Double Star EP
I purchased this for measuring the separation and position angle of double stars, and, after calibrating, this does the job nicely. There is a good deal of material on the Internet about how to use these astrometric units (two others have been or are...

Antares 1.25" Kellner Eyepiece with Focusable Cross-Hair - 27mm
Perfect for precise GoTo alignment
Works perfectly for more precise GoTo alignments as well as daytime finder/scope alignments. I was worried that a non-illuminated reticle might prove too dim for use, but not at all (and my eyesight is not that good anymore). Looks sturdy enough, and...

Antares 1.25" Kellner Eyepiece with Focusable Cross-Hair - 27mm
Works OK
I wanted more accurate alignment between my telescope and my spotter, this did the deed. Came in a nice Agena plastic "bolt" case too.

Antares 1.25" Kellner Eyepiece with Focusable Cross-Hair - 27mm
A good eyepiece for the price
It would be better if this eyepiece has a wider field of view (70 deg). And yes, the price will change if the fov is wider.

Agena 1.25" Cheshire Collimating Eyepiece for Newtonian Reflectors
Functional at a very good price
Works very well for collimation of my 12" Dobsonian and is good for verification of laser-based collimation as well.

Agena 1.25" Cheshire Collimating Eyepiece for Newtonian Reflectors
Very well satisfied with the CE.
It was even better I beleve, than the 25 year old tool that I donated along with my 8 inch dob. Now I have just a little 4 1/2 inch dob that needed collimation in a big way.

Antares 1.25" Kellner Eyepiece with Focusable Cross-Hair - 27mm
Low build quality but works somewhat OK
I was looking for an eyepiece with reticle, so that I could use it for a 3-star alignment of my recently-bought Celestron telescope with the GO-TO functionality. Most of the reticle eyepieces had a focal length of 12 mm, which provided too little fie...

Agena 1.25" Cheshire Collimating Eyepiece for Refractors
Simple, effective!
If you own a refractor and want to squeeze every drop of performance out of it, you need this product to ensure it's collimated precisely! Improved the views in my 120mm and 150mm refractors!

Agena 1.25" Cheshire Collimating Eyepiece for Newtonian Reflectors
Great tool for Newts
I don't completely rely on laser collimators, as THEY can often be misaligned themselves. This "old, analog device" is extremely accurate! Used in conjunction with a laser, I can collimate reasonably fast and with "dead on" accuracy! A MUST for seri...

Agena 1.25" Cheshire Collimating Eyepiece for Newtonian Reflectors
Gets it done
If you go to the fancy laser collimator route you have to make sure you stay away from cheap models which might not be accurately aligned. So instead of spending a lot of money to get a laser collimator that actually works, you can go the Cheshire ro...

Agena Cordless Illuminator for Reticle Eyepieces
Valuable add-on
This reticle illuminator fits 2 different brands of illuminated reticle eyepieces I have. The construction is very robust and it appears reliable. it is a bit large and heavy compared to the plastic illuminators, but the metal construction is a big p...

Agena 1.25" Wireless Illuminated Reticle Eyepiece with Focusable Crosshair - 12.5mm
Loose focuser
I like this product and it performs well but it has one flaw. To focus the illuminated reticle, one needs to twist the top of the eyepiece. The threads are very loose and it won't keep focus after removing or handling. This is a minor, but annoyin...

Greatly Aids Alignment
I use this lens in the alignment of my go-to telescope and it greatly speeds up the process. It's well worth the investment.

Antares 1.25" Kellner Eyepiece with Focusable Cross-Hair - 27mm
Exellent for alignment stars
For years, I often struggled with getting low warp factors for my 10 inch Orion Intelliscope. General opinion is not in favor of a centering eyepiece, so I put off the purchase. The usual advice is to defocus the star in the eyepiece to center it. It...

Great for Accurate GOTO Alignments
This EP has greatly reduced frustration and increased the ease and accuracy of GOTO alignments on my Celestron AVX. I'm using it with an 8" Edge HD SCT. The 20mm FL, 70 degree AFOV gives a decent TFOV with the SCT. Center the star in the box formed...
