This 3.375” square by 0.225” thick flat base adapter plate has holes in each corner that allow it to be bolted to a truss tube Dobsonian’s flat focuser board. The center of the adapter has a 2.75” diameter opening that accepts the body of any Feather Touch focuser. Three recessed setscrews in the adapter fit into a groove in the Feather Touch focuser body to lock the focuser in place. If you are unsure of whether your focuser board is precisely at right angles to the scope’s light path, consider instead the #FT-SFBL flat base adapter with leveling screws. This option will let you fine-tune the collimation of the focuser with the light path. Precision machined of aluminum and black anodized.
