Agena's new Multi-Target Reflex Red Dot Finder is a big improvement over the typical plastic red dot finder found on many telescopes. It is waterproof and shockproof and is well suited for astronomy, bird watching, and other daytime or nighttime applications. This reticle finder has a tubeless design with a 22mm x 33mm reflex lens aperture, providing a wide field of view with unlimited eye relief. The finder features a durable and attractive, black anodized, all aluminum construction.
A variable brightness red LED projects four different target patterns at the flick of a switch (dot, crosshair, crosshair with dot, and circle with dot). The reticle can be adjusted in brightness in seven increments for practically any application (including daylight use) to suit your preference. It is powered by one 3V lithium battery (CR2032 or equivalent) which is also included. The battery will last for a long time due to the finder's efficient low power consumption design.
The optics are coated for improved transmission (however, a fainter double or reflected image of the reticle pattern is commonly seen in darker conditions depending on the pattern and brightness level selected). A rubber dust cap for the reflex lens is also included. After mounting the finder on your telescope, you can adjust it in elevation (altitude) and azimuth (left-right) to align it with your telescope. An allen wrench is required for this (included), so the finder alignment cannot be upset inadvertently once it is set.
The Agena MRRF is available with with two mounting options. This model includes a mounting stalk (bracket) and a slip-fit type dovetail base as shown in the product photos. The base is drilled with 3 holes that can accept M5 or M6 screws to attach the base to your telescope. Two M5 screws are included for this attachment, but you often just need to use one screw on most focusers. This is the screw size most commonly used on focusers made by William Optics and Long Perng (but not GSO). The mounting has a quick release fitting which allows you to replace the finder in the same position between viewing sessions, saving a lot of time re-aligning.
