ALWAYS pays to ask first.

Hi all,

Thought I'd share a little cautionary tale of the importance of needing to see what you are getting first before laying your money down. Buying sight unseen can be a very risky exercise.

A set of 9" Intes Maksutov Optics came up for sale via the grapevine. Of course I jumped at the chance, and asked about them. First reply I got had no photos attached. Fair enough I thought. When I asked for photos, oh my, what a shock I got! I've attached the photos I received.

* First, pay close attention to the corrector - there are chips along the blackened edge.
* Second, look carefully at the secondary - it is damaged on its left side, and a hairline fracture arcs out from the damage across the whole face of the secondary!
* Third, the primary is filthy. Really well looked after, not...

And this bloke had put the word out that he had a set of Russian optics available!

One less Unicorn left in the world... Very sad as they are not breeding any more.

Alex.

PS, the secondary mirror is the small separate mirror in the first & third pics. In a Gregorian Maksutov the secondary is a silvered spot on the corrector. In a Rumak Maksutov, and secondary is a separate unit altogether, like that of an SCT. This allows the manufacturer greater flexibility in parameters in desiging the scope.
