I have for sale a brand new, unopened Ultra Grade 300mm F4 Orion Optics UK primary mirror and 100mm mounted secondary mirror. Ultra is the highest grade of mirror produced by OOUK and this primary comes with a Zygo test report which reports the Strehl at a very impressive 0.991!!
The sale also comes with the OOUK primary cell (currently set up for a 344mm ID tube), a Kendrick extra large dew heater (2029-XL) for the secondary mirror and smaller spare lugs for the primary cell if you have a smaller diameter tube.
