Fantastic Eyepiece

Purchased this eyepiece splendid with my 10inch skywatcher a little bit powerful at 3mm I'm sure would be good if weather was clearer as I tested while there was a bit of haze but first night seeing Jupiter with its Ganyemed moon and red spot crystal clear also tested it on my Gso c6 f/12 also fantastic as for postage ultra fast just 10 days on standard shipping to Aus Svbony is a pleasure to do business with can count on there affordable and quality products keep them coming!!!!
