Mint William Optics Megrez 80L optical tube assembly. The "L" simply stands for the model: it is the one with the tripod mounting bracket v. the one equipped with a pair of mounting rings. It is referred to as the 80L in the printed materials from the factory.
It is the regular F6.0 480mm doublet w/SD glass, which was marketed by Wiliam Optics as "semi-apo" because of the color correction properties of the SD glass (which is often used in higher-end camera lenses, in addition to ED glass). Using SD glass in one of the two elements provides an improvement in color correction over the usual crown/flint combination - hence the description as "semi-apo". Only the high end WO scopes that use fluorite are true apos, as we think of them.
I am the original owner of this scope, which was purchased in December 2003. I have all the original paperwork, including the Quality Control Checklist when it left the factory in September of 2003, as well as the Limited Product Warranty, which is still valid through the end of this year. ("Product Warranty applies to the original purchaser and to any subsequent purchasers during the warranty period.") I have the original sales receipt, which I will also give to the buyer.
The scope saw little use since I upgraded to a bigger ED scope, so this is the right time to let this one go since it is still under warranty. The ota comes with the original William Optics case and the 2" to 1 1/4" adapter. The kit I bought did not include the mounting rings, but I do have a nice set (not the WO ones) available for separate purchase if needed. The kit did not include the WO violet filter. It did include a 2" 90 degree diagonal, but that is not included because it is being used on my new scope.
Any questions, please send me an email. I prefer PayPal and can ship immediately upon receipt of funds. Thanks for looking!
