Rigel Systems QuikFinder
Pleased with the Rigel Quickfinder
Excellent product. The only reflex finder I think is better is the Telrad, but that is way larger. I have both, this is on my smaller refractor. I recommend the Rigel if you have a small scope or are saving weight.

Baader Semi-APO Filter - 1.25" # FSAPO-1 2458398
Very nice to sharpen an achromatic refractor.
At the cost of dimming the image a little bit, it cuts down chromatic aberrations without too much impact on color balance. It also removes some light pollution (as long as your town still uses sodium lights). It certainly increase the usability of m...

Very well done!
Nice one, perfect size, not the tall high ones , keeping the objects very close to my telescope’s ep. I really like it. Mine came in very good conditions. I would like to summit a picture attached to my refractor.

Optolong City Light Supression / Light Pollution Reduction CLS Filter - 1.25"
Very Impressed.
This CLS filter fit perfectly into my unmodified Canon 5D Mark ii . I just set my camera for mirror lock up, pressed the shutter release to lock up the mirror and then just popped in the filter. I’ve tested the filter and am very pleased with the r...

Just what the doctor ordered!
Works perfectly as attached to the GSO 2" Crayford focuser (also bought from Agena). The GSO focuser was used to upgrade my Orion StarBlast 90 f/7.3 achro, and this bracket holds my 8x40 straight-through finder securely. Recommended.

William Optics 2" 99% Dielectric Dura Bright Carbon Fiber Mirror Diagonal for Refractors
Nice diagonal
First off, just so you're aware, this thing is not small. I put it on a Celestron 6SE with no problems at all. Removed the visual back, screwed this right on. Build quality feels nice and solid. The large thumb screws are nice and work well. The...

Baader Premium Eyepiece Filter: Yellow, 495nm Longpass - 1.25" # FCFY-1 2458301
495 Longpass Filter
I have two small fast achromatic refractors and this filter eliminates the purple fringing on bright objects helping me to see more detail. It does produce a strong yellow coloring to everything viewed, much more so than a #8 light yellow filter, but...

Vixen 7x50 Straight-Through Finder Scope with Illuminated Crosshair # 8616
Texasa Slim
Aside from the usual Vixen quality (optics and mechanics), this higher-end finder has an illuminated reticle which, unlike cheaper models, does not flare when the brightness is turned up. In addition, the illumination is internal and not provided by ...

Celestron 1.25" 45-deg Erect Image Diagonal # 94112-A
small internal prism causes vignetting, reduces FOV
This 45* correct image diagonal prism actually has a clean, sharp image. The problem is that becuase of the small prism (20mm trying to feed 32mm eyepieces), the outer 10% of the FOV is vignetted... that is darker than the other 90%. For that reason...
