Marvellous do-everything eyepiece

Wednesday, 29 August 2018 | Daniel

Bought this eyepiece because it has long eye relief (20 mm) and relatively large field of view. I have used it with a Tak FC-100, Vixen SD81S, Vixen A80M and Celestron C8 on moon, planets, double stars and DSOs.

Performance is excellent, producing excellent sharpness and contrast, and aberrations are extremely well controlled. Also, the eyepiece has an excellent quality feel to it. Highly recommended.
