Product Description
This is the same eyepiece used on our finder scopes. It is a very sharp 23 mm focal length eyepiece with a 50 degree field of view and a 20.5 mm field stop diameter. The cross hair is a reticle that may be focused. This eyepiece accepts reticle illuminators such as our EI002. Purchasing an illuminator is advised as it is difficult to see the crosshairs at night.
This eyepiece has generous eye relief and a fold down rubber eyecup.

Great for centering an object and aligning scope
Good product. I was bale to use an illuminator I already had in my inventory, saving me money on having to buy a new one. The 24mm focal length works well with my 1500mm focal length scope, giving me enough sky to find an object for alignment purposes. Quality of build is very high and optics are good. However, I was unable to put any filters on the 1.25" end of the eyepiece. It appeared to be threaded, but none of my filters would fit. I guess this eyepiece will be a specialty piece that will only help me align my Celestron Nexstar 6SE. Before I placed my order, I called Stellarvue and immediately spoke with the owner who answered my questions quite well. Very refreshing!
