Asked by: Anonymous
Well it depends on the Focal Length of your scope. That is what determines the power of this eyepiece technically. You take the Focal Length of your Scope and divide it by the Millimeter of the Eyepiece.

question

is this eyepiece good for long range birdwatching?
Asked by: Anonymous
I think it is just about the best ep for birding. With a larger scope it will have more power for long distances.
