The EarthWin Optical Power/ Filter Slide includes two empty filter cells which can be loaded with 2’’ filters by the user. Filters are held in place by a non-marring nylon tipped set screw and tightened with a supplied hex wrench. The Filter Cells can be loaded or easily withdrawn from the housing and replaced by different cells in a matter of seconds.  Extra 2” filter cells and 1 1/4” adapter cells can be purchased separately and come in square plastic filter cases.  The Filter Slide is independent of the Power Slide so filters can be introduced at any time.

Our Dioptors are a non-marring split ring design that centers and locks the eyepiece as the user tightens the top knurled ring.  To load an eyepiece simply hold the bottom knurl firmly with one hand and rotate the top black knurled ring counter-clockwise to loosen enough to recieve an eyepiece. Once the eyepiece is inserted,again hold the bottom knurl firmly and rotate the top black knurled ring clockwise until eyepiece is firmly tightened.  Now, with eyepiece locked into place, both rings can be used to dioptor.

Start with the dioptors rotated all the way down(clock-wise). Use the procedure to load the eyepieces into the holders. Now rotate the each dioptor 1/2 turn counter-clockwise. This will be the starting point to focus the binoviewer system with the telescope focuser. When close focus is achieved, fine tune each eye individually using the dioptors by rotating positive or negative. Take notice of the final position of the dioptors while system is in focus. This will help you in developing your own method of adjustment.
