Meanwhile here is some reading for you on the ES.

I feel that this thread would have gotten more attention it were placed in the Eye Pieces Forum. Meanwhile Matt, all the best in your search for your eyepieces.

FYI Suzy, these thread and reviews are obsolete. The new generation ES 82's have a different design. Eg. the 24 mm N2 is over 200 grams lighter then the last generation. Even my big 30mm weighs just a few grams more then the old 24mm. Still not light but even with the coma corrector and the 30mm I don't have any balance issues since I use a skywatcher dob with the adjustable tension bearings. That being said a GSO dob wouldnt have any problems either. If you have adjustable tension bearings on your dob, it should be fine in an 8 inch.
