Mirror Resurfacing for Celestron 8"SCT

Hello,

I have a Celestron Super C8 that has an ailing secondary mirror. I have contacted Celestron, and also emailed other companies that offer resurfacing of optical mirrors. I have received a quote from a company called "majestic-coatings". They have quoted me a resurfacing charge of $90 for my primary mirror and they will resurface my secondary mirror for free. I was wondering if any of you have had experience in this area; Majestic told me that after the resurfacing the mirror would have a average reflectivity of 91% The standard coating offered is Aluminum with a Silicon Monoxide protective overcoat ( Al/Sio ). Anyhoo, thanks in advance for your responses...

I have a C8 with an failing main mirror.

I contacted Celestron and they are asking $325.00 for this service.

I am curious if the average person can remove the main mirror from the mirror carrier/cell and get it back together without the need for Celestron factory collimation? I know I can remove the mirrors from the OTA, but the main must be removed from the mirror carrier/cell. I have read many warnings to NOT do this.

Comments?
