I know that there are practical upper limits for magnification for a given
scope, but is there also a practical lower limit to magnification? I built a
10" F5 truss tube dob and used a 1.25" focuser on it. My lowest power
eyepiece currently is a 32mm Plossl (40X). So, how low can I go, and would
there be advantages other than FOV to lower power with my setup?
BTW my highest power eyepiece is a 13mm Nagler (97X) and I carry a 2X
Barlow.
Thanks in advance.
