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 type B1 mounting stalk (bracket) and a deluxe Vixen / Synta type cross-slot XFURB dovetail base as shown in the product photos. The finder 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. Perpendicular to the telescope's optical axis, the included base can be used with mounting hole spacings ranging from 10mm - 29mm (0.39" - 1.14") if you use 5mm mounting screws. Note that this spacing is not sufficient to be used on 8" and larger SCT telescopes. For use with SCT telescopes, you will need to replace the XFURB base with the larger SCTFURB base (sold separately). However, your finder may need to be realigned later if used with / removed from the SCT base.
