      5.0 great 1x finder

      Pros:

      Cons:

      Comments:

      I already had another one of these as well as some similar models from other manufacturers. the other ones didn't dim enough, had poor resolution or non-positive adjustments so when I needed a new 1x finder for my C8 I went straight to the WO unit, even though it was more money. you get what you pay for.

      4.0 Red Dot Finder

      Pros:

      Cons:

      Comments:

      This finder is well designed and strongly built. Very supperior to the cheap plastic RDF. Using it is easy enough but I don't like needing an Allen wrench to make pointing adjustments, esp in the dark. Fundamentally I am well impressed with this product and the AgenaAstro company.

      5.0 NICE

      Pros:

      Cons:

      Comments:

      In short, it was a no hassle install and it works great with my f/6.

      Well made and rugged, the W.O. Red Dot Finder attached easily and quickly to my W.O. ZenithStar. It features machined metal construction - no plastic here. All you need is provided including stalk bracket, mount, attaching hardware and a battery . The finder has eight brightness (0 thru 7) settings with "0" being off. It also has four selectable red dot sighting targets. The sight objective comes with a rubber dust cover/protector. Out of the box, the finder came nearly spot-on aligned so I didn't have to sight it in with the OTA. Recommended.

      5.0 A great little RDF

      Pros:

      Compact,Quality Lenses,Strong Construction,Easy to Use,Accurate

      Cons:

      Comments:

      This RDF is solidly built and dims down very well for Astro use. No complaints at all, if I need another I will buy the same thing. Used with my AR102 in place of the unusable straight through 8x50.

      5.0 Nice finder!

      Pros:

      Compact,Lightweight,Easy to Use

      Cons:

      Comments:

      Awesome M5 RDF! The engraved swan is a classy touch, too. If you have any scope with a Long Perng tube assembly (William Optics, Astro-Tech, etc.), this is the perfect RDF for you. I also really liked the solid, all metal construction. Good job, Agena!

      2.0 A Pain to Adjust In The Dark

      Pros:

      Lightweight,Strong Construction,Quality Lenses,Compact

      Cons:

      Difficult to Use

      Comments:

      First, let me say that Agena Astro is a great place to buy your gear, they have treated me like a king since I first discovered his web store.

      The WO finder is a well made, metal unit, with a choice of patterns. I have 3 of these, and they're nearly impossible for me to adjust in the dark due to the use of allen head bolts for adjustment. The range of adjustment is pretty limited, too, and I just can't get them to work for me. YMMV. A high-quality product, but needs a little engineering work. How about using knobs instead of an allen wrench. An allen wrench? In the dark??
