Arcturus 2-1.25 Standard Eyepiece Adapter

A Low Profile standard Eyepiece adapter that permits use in almost any focuser on the market.

This relatively low profile adapter only raises the eyepiece by 12mm from the top of the focuser allowing just enough room for the thumbscrew to not interfere with the drawtube of the focuser.

A lower profile adapter than this one would require the provision of a "cut" in the top of the focuser tube in order to allow the thumbscrew to drop into proper positioning for clamping.

In addition, the adapter is threaded to accept 2 inch filters. Simply move from one 1.25" eyepiece to another without the need to transfer your viewing filter from eyepiece to eyepiece!
