Product Description
The Explore Scientific finder's large 50mm aperture has a limiting magnitude of 11, fainter than the stars on any commercial star chart, making it easy for you to locate faint nebulas and galaxies. The field of view is a generous 6 degrees wide. The illuminated reticle of the finder has crosshairs with scale markings and an open center that not only helps you center objects precisely, but lets you judge the exact field of view in degrees.
The finder weighs 15.9 ounces, including its standard equipment finder bracket. The bracket fits into the dovetail shoe mounted on all Explore Scientific scopes that do not have a finder as standard equipment. An optional mounting shoe is available for installing the finder on a scope from another manufacturer. The finder body is aluminum, with a black anodized aluminum lens cell and diagonal.
Rotating the eyecup of the supplied illuminated crosshair reticle eyepiece focuses the crosshairs of the reticle to match your eyesight, while a separate ribbed ring at the front of the finder body focuses the objective. The brightness of the Explore Scientific 8 x 50mm finder's reticle is controlled by a variable brightness knob on the cordless illuminator, which also serves as the illuminator's on/off switch. The illuminator's deep red illumination will not disturb your dark adapted vision.

Reviews
The clear anodized coating matches the grey trim well on the AT 102ED also. A well constructed high qualith finder. (Posted on 9/26/2019)
I prefer the ergonomics, twist focuser and wider field of the ES RA finder, but that one is significantly more expensive.
Keep in mind the finder base only fits ES and Meade finder shoes. An adapter or new mounting rings are required for other types of finder base. (Posted on 9/1/2019)
