ADJUSTMENT PROCEDURE

Step 1 - With eyepieces in and lens cap off, insert system into your focuser.
Step 2 - Push thumb tab 1 to the center position (Fig. C) and bring to focus. If focus is not achieved, then withdraw system from focuser.

Step 3 - Un-thread adjustable sleeve out approximately 1/4’’ (Fig. D) and re-insert into your focuser. Bring to focus. If focus is achieved proceed to step 4. If not, repeat this procedure until focus is achieved.

Step 4 - With focus achieved, tighten lock ring. (Fig. E) No further adjustment will be necessary unless used in a different newtonian.

Low power - 1.4X - push thumb tab 1 to center position,Fig. A, then bring to focus.

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 The Filter Cells can be loaded or easily withdrawn from the housing and replaced by different cells in a matter of seconds (see Fig. F).  Extra 2” filter cells and 1 1/4” adapter cells can be purchased seperately and come in square plastic filter cases.  The Filter Slide is independent of the Power Slide  so filters can be introduced at any time.

Step 1 - Completely un-thread  “adjustable sleeve”  with lock ring  and lens cell from the nose piece. Keep lens cell covered and store in case. Refer to Fig. A.

Step 2 - Load binoviewer system with  Power/Filter Slide, into your diagonal. You are now setup for use in a SCT, refer to Fig. B.

High Power - 1.7X- Thumb tab 2 pushed to center position (Fig.E) focus.

*NOTE - Lens Cell can be threaded onto nosepiece for three different magnifications.

Step 2 - Un-thread lens cell from adjustable sleeve and thread into the nosepiece of your diagonal. Insert diagonal into your refractor.

Med Power –2X- Thumb tab 1 in Left position,---Thumb tab 2 in right position (see Fig. D) and bring to focus.

High Power – 3X- Thumb tab 2 pushed to center position ( see Fig. E). Focus.

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.
