Agena's new XFURB Deluxe Mounting Base / Shoe features a new, unique cross-slot screw hole pattern, making it usable on a very wide variety of telescope tubes.
This base can be mounted on tubes that are 3.5" or larger in diameter (not telescope aperture), as well as flat surfaces. The long slots on the dovetail base also allow you to suitably position the finder at the most convenient or usable location on your tube or focuser, especially if you attach it to a Crayford focuser body using just a single mounting screw.
The screw slots can accomodate screws up to 5mm in diameter. So commonly used M4 or M5 screws will both work with this. Perpendicular to the optical axis, this base can be used with mounting hole spacings ranging from 10mm - 29mm (0.39" - 1.14") if you use 5mm mounting screws. With 4mm mounting screws, hole spacings can range from 9mm - 30mm (0.35" - 1.18"). Note that this spacing is not sufficient to be used on 8" and larger SCT telescopes if you want to use both mounting screws. However, it will work if you use only one screw, and the attachment will still be very rigid on SCTs.
If you happen to have a telescope tube in which the mounting hole pattern is along the optical axis, then this base can be used for hole spacings ranging from 9mm - 32mm (0.35" - 1.26") with 5mm mounting screws.
Virtually every other dovetail base on the market allows you to use only flat head screws. The recessed screw head slot on this base allows you to use most screws with even oval, hex, button, or other head types besides flat head screws as long as the screw head height does not exceed 3.25mm.
The base is made of die-cast metal and features a smooth black finish and two large locking thumbscrews (style of thumbscrews pictured is subject to change without notice). The center-to-center distance between the two locking screws is 24mm (0.94"). Total footprint size of this base is 42mm (1.65") perpendicular to the optical axis and 38.9mm (1.53") along the optical axis.
Note that some Synta / Vixen style brackets often have a small extension that slots into compatible bases to prevent slippage. This base does not feature this indented slot, so your finder bracket might stick out of the base by a little bit.
Please also note that no mounting screws are included with this base.
Additional Info
When ordering any Vixen style dovetail base (shoe), bar or plate, please note that there are two different size standards and applications in the industry. A Vixen/Synta dovetail base such as this Agena product is smaller and generally has a slot opening to accommodate 32-34mm finder bracket dovetails. A Vixen base/clamp/saddle for mounts and telescopes is wider at 42-44mm. The two are not the same and are not interchangeable.
