Fits any diameter telescope tube except Schmidt-Cassegrain telescope optical tubes; the base is made of die-cast 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 or 0.79" in order for this dovetail base to be compatible
A finder scope shoe is all need - mounting is easy; just slide TriFinder into existing finder scope shoe; now have 3 Vixen/Synta slots at disposal; attach a finder scope to LED finder and perhaps a laser pointer; easily be able to locate any faint object
A holder for mini guide scope: astrophotographers like to use them with auto-guider; but best thing is easy to install and fit into the Tri-Finder; so astrophotography is perhaps not young generation play; but becomes a lot easier
