The Daystar Filters 2 Inch Eyepiece Holder extends the functionality of the Daystar Quark by maximizing the visual solar observation experience. Simply unthread the standard 1.25 Inch Eyepiece Holder that comes standard with every Quark, and replace with the 2 Inch Eyepiece Holder. This quick and simple adapter change allows Quark users to add the 2 Inch eyepiece of your choice (Daystar recommends the Tele Vue 55mm Plossl).  

Like the 1.25 Inch Eyepiece Holder, the Daystar Filters 2 Inch Eyepiece Holder includes a brass ring clamp that is tightened with a thumbscrew. Note that both the 1.25 Inch and 2 Inch Eyepiece Holders come with the standard Quark threading, so no need for additional adapters.
