** ALL SOLD ** (Thanks Mark!)
These are the optics for a portable telescope project I built back in 1986. The mirror was purchased from Sky Optical in March 1986 - serial no. 1608. They were a Coulter competitor, and the quality is similar. Think of this as a great light bucket mirror - you wouldn't be happy with it for high mag planetary work, but you can see a whole lot of faint fuzzies with it.

The mirror is 10" (nominal f/4.5) with a focal length marked on the side of 42.5". Mirror is 1.5" thick. It's center marked (with red nail polish) and the coating is in very good condition. It comes with a homemade mirror box (see pic), and if you want, I'll throw in the sling mirror board I made. Price is $125.00

The 2.6" diagonal and holder are from Novak. The elliptical mirror is also "center" marked - assuming a centered secondary and an f/4.5 system, so if would be offset for other applications (sorry). I'll include a homemade two vane spider. Price is $30.

I have lots of other photos of this stuff, I'm happy to send them along to anyone who is interested.

Buyer pays actual USPS shipping and insurance. Let me know if you have any questions.
