Thanks, Greg. You're going to love this thing!
Here is a Siebert binoviewer with 2 Siebert 21mm wide angle EP's. Comes with a removable, internal 1.7X barlow that allows focus in Newts and refractors with a diagonal. A non-barlow barrel, vinyl pouches for everything, and manual are also included. This is the 2000 version with 1.25" set screw type EP holders and sliding diopter adjustment. Plastic set screws won't mar your EP's.
$300 shipped USPS Priority to the lower 48. Paypal preferred.
I originally paid $400+ shipping for it.
This model has been maligned for the way it looks, but I find it to perform beautifully, showing minimal scatter, excellent convergence, and razor sharp planetary & lunar performance, especially with Plossls. Not too shabby on M13, either! Interocular spacing is smooth & simple, and stays where you put it. Only selling because I have just struck a deal for an AP/Baader unit for a heckuva lot more dough.
