Does anyone have any suggestions of who might coat a 25" primary mirror? Mine is very near the state of needing to be recoated.

Majestic Coatings and Spectrum Coating both say their limit is 24". I've used Clausing for many years but have heard bad reports lately.

I've been staring over 50 years, enjoying deep sky as well as double star observing.

I've had my 25" coated by three venders. You can contact me PM for my experience and honest advice. Martin

If you haven't read it, you might find this thread worth reading:

You might want to ask prospective coating shops if they assume responsibility for a damaged mirror, say if they were to drop it...
