Mirror ordered on October 22, 2008
|

UPADATE AS OF 12/10/08 - At least four weeks away from my order being filled due to a huge backlog in the Royce shop. I'm not expecting the primary until middle of January.
My order for an 8-inch F/5 Royce conical primary mirror has been placed. Bob Royce chatted with me briefly on the phone and indicated a probable delivery date around the middle of December.
I went with his standard coating which is ~94% reflectivity. Other exotic coatings are available in the 95-98% range but I've learned that these are exremely difficult to remove when it comes time to recoat the glass. In many cases the entire blank has to be refigured which gets expensive.
I'm actually very content with a timeframe of 7-8 weeks. This will give me more than enough time to quit obsessing over the remaining components and get them ordered.
UPDATE (Feb. 20, 2009) - Bob Royce has given me a new prospective delivery of the conical primary mirror sometime in late March.
