I have a SV105 on the way and am trying to plan which eyepieces and optical compensators to start out with for lunar/planetary viewing. I have a DenkII with Denk 21 mm eyepieces that I would like to use. With the universal powerswitch that I have, I will get 1.25x (39x), 1.8x (55x),
and 2.25 (68x) in the SV105.
The options I can think of now or to get a higher power S unit from Denkmeier to shift all the magnifications higher or stick a 2x or 4x powermate in front of the diagonal. I wish there was a 3x powermate as that would seem to be ideal but I am guessing as to what the best magnification range will be with the SV105 and a binoviewer.
As a side issue, will I run out of light at high powers when binoviewing with a 4 inch scope and perhaps save the high power viewing for single eyepiece viewing?
