Hey guys - Another newbie question.... please bear with.
I see there have been many different designs of eyepieces over the years. ( Plossl, Nagler, Huygens, Erfle etc,) some with 1 or 2 elements, some with 8 or 9 or more! I get that they're named primarily for the designer, and I've seen layouts that show cross sections of each of the designs showing number of elements in the eyepiece. Many of them are simply better designs from a previous design, where additional lenses have been inserted to correct specific inherent aberrations. I understand there are high quality to low quality, expensive to low cost, in each of the designs, by the various manufacturers. Coatings have improved over time. But cost doesn't necessarily determine image/eyepiece quality. Some company's plossl may be better than another company's Kellner (Just an example - EVERYBODY's Plossl may be better than the best Kellner! - No offense Kellner fans.)
So, are there better designs for viewing different types of objects? Different designs best for splitting stars? Galaxies? Nebulae? Planetary? I've got a box full of ES 82s in all different fl's, they're great for everything I've seen, but can a different design be better for a different target. Maybe the modern eyepieces have better glass and coatings, but I notice many of your signatures list many different brands AND designs of eyepieces. You may not use them, but you list them!
Perhaps the difference in fields of view or focal length are the only factors to consider but perhaps different eyepiece designs are important too. Maybe not. But I'm curious...
I already know... "Just get a box full of Ethos and you won't have to worry about it." I'm asking a serious question here!
Like I said, I've seen the cross section comparisons, but if you've found a resource that shows best eyepiece design for different type target to view, please share. Thank you!
