This Siebert barlow was Harry's jewel at one point and receives excellent reviews due to the fully multi-coated Edmond Scientific optics and solid construction. The unit is in perfect condition optically and mechanically. Includes both end-caps. I used it last summer on Mars in combo with a 10mm Speers-Waler for excellent planetary detail which did not degrade even at 2.5X ! It's been great on Saturn too.
Original retail was $99.
I am asking $69.00 which includes shipping. Paypal +2%
Thanks for looking.
