Description
The finder that came with your scope was probably a compromise small, dim, and inconvenient. This one isn’t. The 10×50 RACI shows you a correct-image sky down to magnitude 11, the illuminated reticle centers your targets precisely, and the removable 1.25″ eyepiece turns a finder into a working instrument. If you star-hop or if you’ve been frustrated trying to star-hop with the finder you have this is the upgrade that makes the difference. It’s also the last finder you’ll buy.
