Product Description

This right-angle illuminated Explore Scientific 8 x 50mm finderscope has an image-erecting amici prism built into its right-angle diagonal that gives you images that are correctly oriented (upright and right-reading), so that star patterns are seen exactly the way you see them on star charts and with your bare eye. This makes star-hopping from object to object when using the finder easier than with a conventional finderscope's mirror-image or inverted view.

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 7 degrees wide. 

The finder weighs 1 pound, 9.1 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.

The supplied illuminated reticle eyepiece has northern and southern hemisphere polar alignment patterns to allow quick and precise polar alignment with any equatorial mount anywhere in the world. Rotating the eyecup focuses the eyepiece reticle, while a separate rubber ring at the rear 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.

Review by:
This finder has excellent optics, good enough that I've done observing with it as a short focus 50mm scope. The twist focuser is easy to use to get a nice sharp image. The multicoated optics really do give a fantastic, expansive 7-degree view. The adjustment screws, being plastic, leave a bit to be desired but are good enough. The illuminator is quite good, easy to adjust and makes the reticle very easy to use even in the darkest conditions. The eyepiece can be turned to adjust the reticle angle for rough polar alignmebt. It is a bit pricey, but the excellent optics are worth the cost.

Keep on mind that the finder base only works with ES and Meade finder shoes. An adapter or a different set of rings will be needed for other types of finder shoes. (Posted on 9/1/2019)
