UV/IR Cut Filter
Bought this to use as energy rejection filter for a Quark Solar Filter when used in my 120ED. Nice quality and very good value. I do not have a means of testing the cutoff, but it seems to have worked fine for this application.

Same Quality, better price
I’ve had more expensive diagonals and the quality of this diagonal places it in the same league as the more costly ones.

Good finder bracket
This was supposed to be a "blem", but I couldn't find anything obviously wrong with it. Functions perfectly to hold the 50mm Stellarvue finder.

Looking for a well made synta/vixen laser pointer mount...well here it
I received this laser pointer mount yesterday and I'm going to use it tonight for our first star party of the season. This is a solid, well-made product. The pictures shown for this product does not do this item justice. I have a larger sized la...

Lumicon Minus Violet Filter - 1.25" # LF3120

An excellent sharpener, used properly
Many say this doesn't clear up chromatics totally with an 80mm/F5 scope. You do need a more severe filter in that case, but this is a great way to gave super-sharpness from an 80mm/F8. I could see no color shift in a medium long refractor.

Great experience, as expected.
I expect my experience with Agena to be smooth and efficient. In this case, I wasn't disappointed. One note, however - the filters were actually 1.25", mounted. No problems, the filters are perfect, and I hope to be getting some great image...

Excellent!
Bought this because my GSO 2" refractor focuser, installed on my Orion StarBlast 90mm f/7.3 achro, didn't have enough in-travel to reach focus. The deep set adapter on this diagonal fixed that, and now everything is perfect. The diagonal it...

Back to the atlas- at last
I converted a straight thru spotting scope with a fixed eyepiece ( and short eye relief) to a telescope with the ability to change eyepieces- the objective lens went into a home built plywood box and this GSO diagonal allows me to use the Pocket Sky ...

Simply the Best
This all-metal laser mount bracket is extremely well made. It is strong, functional, and stable when attached to the 'scope. Also, it is just plain fun, and easy to use the Laser to bring sky objects into view. In general, i am able to use a sho...

Good Value and Performance
Solid construction, optically good enough with no mechanical or optical flaws at a nice price. I'd like the eyepiece holder to have been removable ( with a T2 thread ) or lower profile but it's in use and makes my 60mm f 16.5 refractor quit...

I really like this finder
I just purchased another of these finders. I find them easy to use, dew resistant, and long lasting. The price is reasonable, the mounting options are flexible, they do their job well, keep their alignment, and don’t add any equipment headaches. I ...
