I am thinking of buying a few eyepieces for myself for christmas. The eyepieces I am looking at are from Andrews Communications.
They are: 2" 80° 20mm eyepiece (includes removable 1.5x Barlow lens) and the 2" 80° 15mm eyepiece.
I am still a newbie to all of this and was hoping that someone could tell how wide 80° really is.
