I had my 2006 18" OMI mirror and galaxy secondary recoated by OMI in 2018.? The scope was mainly stored in my garage under a cover, after coating the scope is stored inside the house (i did not use the light bulb trick, and probably should have). I attached a pic of the mirror before recoating, it was long overdue, but the scope was still producing good images at the eyepiece and with planetary astrophotography. The primary recoat came out great and turnaround time was pretty quick.? I was not aware of OMI closing down, looks like someone has an astronomy-related website with a similar name but I don't see?James?Mulherin (former OMI president and lead optical engineer)?as being on staff.
I think mirrors tends to be recoated in batches, so you might want ask when the next batch will be run before sending in your mirror so you can use it until is is close to time to recoat.?
I will put together a PDF and upload to the file section on (at least one way) to properly pack a large expensive mirror for shipment for recoating, it's something all Obsession owners should know. Others can throw in their two cents.
