EyePieces
Ok, what are the differences between eyepieces, like between a plossl and a nagler for instance.
I know it has something to do with like how many lenses and stuff they have in them, but to a noob like me, who is looking into getting a few more EP's, i would like to know.
At the moment i have a 4mm, 9mm, 12.5mm and a 25 mm Plossl EP's. I am thinking of getting a 40mm EP for wide field. But then I hear of high mag widefield EP's. (I could be wrong about that.)
Any ideas.
