OK, I'm still new at this, so your comments are welcome to educate me. Since my first eyepieces were a 2" 26mm and 1.25" 15mm and 9 mm, I wrongly formed the view that low magnification eyepieces were more likely 2" barrels. However, I'm discovering that eyepieces as long as 40mm fl come in 1.25".
Are there things to consider here, or doesn't it really matter whether an eyepiece is 1.25" or 2" regardless of focal length (overlooking size of focuser, barlow, filters etc.)
Thanks
Eric
