I have for sale an Orion Optics UK Ultra Grade 150mm F4 mirror with a measured Strehl ratio of 99.1. It comes with the OOUK primary cell to which the mirror has been siliconed at 3 points according to PLOP. It has stronger springs installed and mirror clips have been machines to be non intrusive on the mirror surface and add side support at the correct height. It comes with a test report and all of the original hardware for the cell should you be inclined to return it to it's original form. It has not been under the stars as yet.
Current price to land one of these in Australia is over $900.
Selling for $700 including postage or less for local pick up
