Perfect if you bought a Crayford and still want to use a finder scope; the standard dovetails do not fit, but these do.

Planetary filter
I brought the filter in hopes it would enhance the spiral structures around galaxies. It worked especially well on M51 where the spiral arms were enhanced.

It works
I bought this to mount on giant binoculars. Even with a 3 degree fov, you get to your target much faster with a good finder. I like the circular reticule. Since you know the fov represented by both circles, it is good for star hopping. I like that ...

A very beautiful piece of equipment! Can't wait until the weather once cooperates so I can finally use it. Solid and well built and I'm sure it'll perform beyond my expectations.

I does the job. This is a basic 1.25" mirror diagonal (that would cost $50) with an ITF (the maier photonics equivalent would cost $75 and the BelOptik equivalent about $200) and the blocking filter itself. This mens that we are paying about $35...

Great With My ST80 Clone
I bought this to replace the correct image prism diagonal that came with my ST80 clone, which is a Meade Adventure Scope. The prism was ok for lower magnification terrestrial viewing, but not for astronomy. This GSO mirror diagonal is lightweight and...
