The Baader Universal Quick Release dovetail finder base (finder-shoe) # 2457000 is compatible with most standard Vixen or Synta style finder brackets and red dot finders, including Baader's MQR-III, MQR-IV, and Sky-Surfer V finder. The base can also be used as an additional base on telescopes that don't already have a finder shoe in a convenient position.
It is CNC machined with a curved base and features elongated holes for a good fitting to almost any telescope, including Schmidt-Cassegrains (SCT). The Baader finder base has two elongated holes for screws up to M5, with either a countersunk head or a flat cylindrical head. Spacing between the screws can range from 27-45mm. In addition, the base has a central countersunk hole for screws up to M5. Screws and nuts are not included.
This item is an excellent replacement for the finder base on many Explore Scientific telescopes. Replacing the original Explore Scientific "Meade-style" base with this item allows you to use the much more common Synta / Vixen style finder brackets on your telescope. However, please meausre the hole spacing on your specific Explore Scientific telescope first to ensure that it meets the hole spacing criteria of this Baader base.
Baader part number DOVE-B or 2457000 or 2457000a.
