Huge eyepiece, fantastic quality
Thursday, 25 August 2022  | 

First things first, this eyepiece is absolutely enormous and very heavy, its only achilles heel, my telescope needed rebalancing every time I put it in the diagonal. Quality is outstanding, build quality, fit and finish, is in my opinion the best I have ever come across, no surprise to see made in Japan printed on the eyepiece. The thing that surprised me the most when using it was, it's so wide you can look around in the eyepiece and there is still sky there, I have heard people talk about this but never experienced it myself, very impressive. Overall this product is expensive but worth every penny, I would recommend it to anyone without hesitation.

Pretty Great

This is a big, chunky product that oozes quality. It gives a huge viewing field, loads of light and great pin-sharp optics. It's just great!
