A deluxe, heavy duty two inch diagonal for use with telescopes that have a two inch focuser. This is a heavy duty unit. The main part is milled from a solid block of aluminum. Uses a thick diagonal mirror with a standard aluminized coating. Included with the diagonal is a 1 1/4" adapter.
We take steps to ensure that internal reflections are minimized using a ultra-flat black overcoating on all inside surfaces. We then bench test each diagonal to make sure it is properly aligned and free from astigmatism. No other diagonal under $120 is so thoroughly tested.
This is the ad for the Stellarvue diagonal, It is a very nice unit with the 1.25" adapter. I've used it a few times but it's in excellent condition and has the end caps. It sold for $99.00, but this one can be yours for $60.00 including shipping and handling. I'll acept MO and PayPal. And only ship in the Cont. US.
