I have 2 of the above mentioned ep's in 17mm and 6mm focal lengths.
I have only used one time for testing. 17mm is very comfortable and gives great images. The 6mm is tight on eye relief, but also gave a very pleasing view of Saturn and Jupiter. I prefer to sell as a set for $32.00 otherwise $18.00 each. Price includes shipping in either case. Money order only. I don't do paypal. Pictures available on request.
Thanks for looking,
