Hi Satchmo
Ok here goes, the bino is a Denkmeier, part of the "big easy package" It is a Standard Denkmeier, so does not have the Focusing SCD holders, or the Power Switch.
The bino acts like a barlow with two different powers X 1.4 and X 2.5.
I very rarely use the Bino at X 2.5.
With my scope 18' and focal lenght of 2025mm, the 19mm pans are actually acting as 13.5mm, magnification of 150.
With the 14mm ES eyepieces, in the Bino act as 10mm and magnification of 202.5. With the 6.7mm ES eyepieces, acting as 4.8mm and a magnification of 421 approximately.
As can be seen by these figures, the 19mm and 14mm eyepieces will get most use and the 6.7 for those exceptional nights.
With the 27pan not using the bino(2" not 1.25") the magnification is X 75, so you can see I have a gap between the X 75 and the X 150.
I need a couple of eyepices that would gige me X 100 to X 120 with 1.25" for the Bino. Any suggestions, also the bank balance is low.
If these figures are not correct, please feel free to adjust them
Hope this helps
Cec
