Product Description

The image-erecting amici prism built into the Astro-Tech's right-angle diagonal 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 using the Astro-Tech finder easier than with a mirror-image or inverted finderscope view.

The Astro-Tech's right-angle right-reading/erect image optics also allow you to view near the zenith in comfort with the finder, without having to turn your head upside down, as you do with the standard straight-through inverted-image finder supplied with most scopes.

The finder's image-erecting diagonal has precise helical focusing and a compression ring eyepiece holder. Both are premium touches rarely found in a finderscope. There is a dust cap for the eyepiece holder.

The finder's 50mm aperture has a limiting magnitude of 11, fainter than the stars on any commercial star chart. This makes it easier for you to locate faint nebulas and galaxies.

The finder is aluminum, anodized flat black. It is internally baffled for higher contrast. The integral dew shield is extra long to retard the formation of dew and shield the objective from ambient light. There is a thread-in dust cover for the dew shield and objective, another premium touch rarely seen in competitive finders.

Please note: The 62mm diameter body of the finder will not fit into the standard 50mm finder dovetail supplied with most Celestron scopes. A larger i.d. dual ring quick release dovetail bracket (#ATF50QRB) is available as an option.
