5 of 5 Eyepieces January 4, 2022
Reviewer: Anonymous Person from Dallas, TX United States  
Don guided me through purchases of several eyepieces. His advice was so helpful. In one instance he guided me to another seller for a better option for my scope. He is clearly passionate and dedicated to this business and cares about helping his customers make the right decisions for their scope. Wonderful eyepieces. Wonderful owner. Wonderful experience.

5 of 5 Great optic, very flexible August 6, 2020
Reviewer: Karl Perry from Olympic Peninsula, WA  
I bought this to replace the 13mm Plossl eyepiece that came with my Celestron 6" cat. Though it is a less-powerful eyepiece it is so much sharper I can see planets clearer through this than the 13mm. Its much wider 30mm exit pupil (compared with the 10mm of the 13mm) makes it easy to use with eyeglasses.

Where the 13mm rendered Saturn more like a blob with two arcs, this Baader clearly showed the planet with rings.

This eyepiece has greatly increased my enjoyment of visual astronomy. If you are still struggling with your manufacturer-supplied high-power eyepiece, get this (or the 17mm). You will be glad you did.
