What is the effective difference beween 1.25" and 2" diameter eyepieces?
So as per my other post I am a fresh starter having just got my first proper scope yesterday after appreciating many years of a simple fixed 20x50 refractor.
I'm primarily interested in planetary viewing and will eventually consider purchasing an additional planetary eyepiece to complement my existing 25 mm wide angle and 10 mm EP's once I've had a bit of practice with what I have.
Clearly there are as many choices with eyepieces as there are with scopes..
My unit's focuser assembly can take either 1.25" or 2" diameter eyepieces. Are there any reasons to choose one diameter barrel over the other *APART* from simple compatibility with a given focuser assembly?
