For 1.3x and 1.3x-2.0x-2.7x Multi-Mag Newtonian/Refractor Instructions for All 2" and 1.25" Binoviewers see Pic's 1 - 19

For Regular Zero and Multi Mag OCA's click here

All Power Mag Wheels  PMW------Starting at Zero and 1.3x. All are setup the same as the regular 1.3x OCA's below. For Dob/Newt (shipped in default position or picture #1.)  For refractor setup use illustrations 9 - 12 

(See text under illustration #12 for more instructions)

 

The only difference between the multi-mag above for the 2" units and the multi-mag below for the 1.25" units is the large upper piece that threads into the bottom of the 2" Elites above and it's counterpart below for 1.25" binoviewers that has an eyepiece holder for accepting a 1.25" focuser shaft.

((For Power wheel models only)) : You need to adjust the slide tube for focus to fit all the magnifications in your telescopes focuser range. Give more clearance away from the mirror by sliding the tube out to the right and you will have more in focus freed up at your lowest power setting if needed. Give yourself about 1/4" to 1/2" focuser  in-travel and it should be good and  allow you to focus your higher powers without running out of out-travel .  (Any questions call email) Personal email> harrysiebert@nc.rr.com or Main>#(1-919-553-3980)
