Things I liked:If you want a versatile sight that can be used in all light conditions... THIS IS IT. I use the same one on one of my telscopes an Clesestron 102 wide veiw. The display is not tinted and a custom mount adapter made for attaching to telescopes is inluded. SRP for #4227 $59.95 from Orion telescope
Funny thing is use a 3-9 x by 40 rifle scope on my 8 inch for teresteral ( long eye relief ) aiming and use the Telrad for celesteral viwing. Things I would have changed:The battery comes lose somtimes when changing brightness. But only when I grasp lid when chaning levels. What others should know:ONLY window shop at retail stores but buy from Pyramid better service and knowledge.
Things I liked: Seven Brightness levels and the 4 reticles makes 28 diferent setting. I purchased the same item with a diferent glare coating. I use it on a Celestron 102-Wide-View Spotting scope. The scope is a 4 inch refracter 500mm f5 scope. This fairly large scope 5" around x 28" long at about 7-8 lbs with attachments.
This site is very easy to use and site-in.
The eye relief is great and reticles are very sharp. They are laser etched Things I would have changed: The battery compartment cap does get lose if you do not hold the ajustment knob correctly. What others should know: This is one of the best bang for the buck I've seen. It is best used for target shooting. Keep it clean just like any other optics used for shooting.
It will not stand up hard use like hunting when not in use store it in a good case.
