120mm/F8 Refractor and Eyepieces
« on: December 29, 2017, 01:16:54 AM »
What is the most powerful eyepiece I can use with a 120mm/F8 refractor? I saw a chart that shows that a 4mm eyepiece is the the most powerful. What is the lowest power eyepiece I can use with a 120mm/F8 refractor? The same chart shows that a 55mm eyepiece is the lowest power. The most powerful and the least powerful that can be brought into sharp focus.

I own a Meade LX70 120mm/F8 refractor.
