A 1.25-inch focuser has a narrower clear aperture than a true 2-inch optical path, so wide-field 2-inch eyepieces may experience noticeable vignetting and will not gain the field of view that a full 2-inch system can deliver. Some combinations may lack sufficient inward or outward focus travel. Check the eyepiece's weight and your telescope or diagonal's load capacity before fitting heavy 2-inch accessories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNot the reverse adapter:\u003c\/strong\u003e to use a 1.25-inch eyepiece in a 2-inch focuser, you need a 2-inch-to-1.25-inch reducer instead.\u003c\/p\u003e\n\u003ch2\u003eWhat's included?\u003c\/h2\u003e\n\u003cp\u003eOne SVBONY W2811D 1.25-inch-to-2-inch metal eyepiece adapter.
