Below, you will find my Field of View (FOV) calculations for the
various eyepieces I use. Calculations are provided for the native f/14
focal length of my telescope. I recognize that (Maksutov-)Cassegrain
optics' focal length is truly an effective focal length due to
varying the separation of the primary and secondary mirrors. However, the
tabulations below are more intended as a baseline comparison of the
relative performance of the eyepieces, rather than a precise
value to be used in some (unclear) way.

- New Telescope:
-
I just got this Meade ETX105/EC. Between
OPT and
COSCO, I am pretty
well equipped.
- Mission:
-
This telescope is a great lunar and planetary scope. I can not see as much
detail as in my 12" SCT, but I will be able to use it at times that I
would not ordinarily consider setting up the 12". The two primary cases
would be grab 'n go
dusk/dawn Venus and Mercury apparitions, and
during times of relatively poor seeing.
- Note:
-
items (if any) in Gray are on order, or will
soon be.
