Re: ATM help me interpret my focal length tests




You do indeed have an F12 scope.  The sun test (FL test) agrees with the ROC
test so you do indeed have what you think you have.  Now go make a 45deg.
(or so) flat the same diameter for it's minor diameter and setup a sunscope.
The image size will be quite nice for viewing the sun with higher
magnifications without needing the 2mm EP.  A 25mm EP will give almost 100x!
