This is a smartphone mount made by Vixen, designed to attach to the eyepiece of telescopes and other astronomical instruments. It allows for position adjustment. - Brand: Vixen - Type: Camera Mount - Adjustment: Position Adjustable - Mounting Type: Screw-on - Material: Plastic I purchased this along with a telescope, but I never used it because I sold the telescope itself. The product itself is a beautiful, unused item, but the packaging has some damage. Please refrain from purchasing if you are overly concerned about minor imperfections, as this item has been in my possession. No returns or exchanges accepted. Thank you for looking.
