Fits any diameter telescope tube except Schmidt Cassegrain telescope optical tubes; the base is made of diecast metal and features a large thumbscrew lock; includes two M4 screws
Compliable with finder scope; Laser Pointer bracket or reflex sight bracket on telescopes; great for adding a second or third aiming device to your telescope
Drilled "but not threaded" to accommodate screws up to 4mm in diameter; center to center screw hole spacing on your telescope must be 20mm "0.79inch" in order for this dovetail base to be compatible
9x50 finder scope with 50mm objective lens diameter; brighter DSOs directly visible; makes a large number of aditional stars available: a big plus for being able to successfully locate objects
Enjoy both comfortable 90 degree viewing angle and upright with non-reversed image; integrated prism displays objects in similar way to that with binoculars or spotting scopes; makes using a star map much easier and observe near zenith at relaxed angle
