6 Inch Telescope Primary Mirror:
The mirror blank is 6 inches in diameter by 1 inch thick. The useful mirror diameter is about 5.7 inches. The focal length is about 16 inches so it is approximately an f/2.8 mirror. The mirror is probably parabolic because of its low f number and it appears to meet Dawes' limit. The photos show an aluminum housing which supported the mirror when it was in service. I can include this housing in the shipment at no extra cost if requested.
