Useful Tool
I have several of these mount brackets that I have used for a range of mounting options. The bracket is well made and provides screw holes for attaching to any surface or tripod.

Nice addition to CG-4 mount!
This is a nice addition to the CG-4 mount. Installation was fairly straight-forward. Remove the older polar mount assembly with set screws by twisting it counter-clockwise. The new polar finder replaces the old mount, threading clockwise and is align...

Great product
With the illuminated reticle eyepiece, I was able to get my Celestron 8SE aligned very accurately the first. It accurately located many DSO's without need for realignment. I am very pleased.

Our astronomy club has 3 of these scopes and they offer wonderful views. That is what hooked me. I opted for the double-stack version to obtain more detailed views of the solar disc. Of all my astronomy gear, this is now my most used scope. We have b...

Porta II panhandle
This product is the perfect upgrade for the ever popular Vixen Porta II. It really makes a difference from using the slow motion controls or grabbing the scope by the diagonal to point the scope.

Highly recommend and a good price

Does the job
My only complaint is that this is made of plastic, which I suppose has no bearing on its functionality, but for the price I expected it to be machined metal.

8mm Brandon (flat top)
I have been using Brandon eyepieces since the early 1970s in everything from 6 inch reflector telescopes to Questars, from SCTs to refractors. They are optically superb and consistent in quality. They don't have the 90 degree apparent field of n...

Baader 2" Click Lock
If you use your GEM for visual observing, you need this accessory. Half the time, the diagonal/eyepiece ends up in a very awkward position making looking through the eyepiece difficult and uncomfortable. Loosening and tightening the set screws was a ...

I bought this for an 8 in reflector. It fits good and snug in the focuser and my collimations has never been better.

Awesome upgrade
I purchased this for an older Celestron C8. I had been using a commercially available circular wheel that fit on the outside of the existing focuser knob but found that solution to be largely unsatisfactory due to a lack of fine control. The Feathert...

Excellent!
Bought this to replace the OEM 1.25" diagonal on a Celestron XLT AZ 102. This is a very solid diagonal, works perfectly. GSO makes great stuff.
