I'm using this eye piece with a Lunt 100mm solar scope, and I like it, it's a good combination. It was expensive but I would definitely buy it again. I have heard all the "bad" points about zoom eye pieces and a fixed Fl eye piece will likely be better But I am very pleased with its performance and of course the convenience of not having to change eye pieces.
I bought this zoom for a friend based on some favorable reviews and it has surpassed by expectations. It is a light, compact piece of equipment. The adjustable eyecup is easy to use and comfortable. The zoom adjustment is not stiff but smooth to operate. Optically it is excellent. The center of the field is quite sharp and contrasty. It works well with a 2x barlow also. Recommended.
I Agree that is an excellent eyepice for planets, mnoon and globular clusters, it is as sharp and has also neutral color as a orthoscopic eyepice, no ghost images, but only extremely sharp at the very center. I think the best zoon.
This is a high contrast no ghost medium to high mag zoom. As compared to common 8-24's no ghosting, focus holds over large change in mag. Very sharp in center shows low contrast detail well excellent for planets, globular clusters and close doubles.The rest of the field is useful for finding and centering your subject.
