Agena Astro certified mirrors
Agena has started a new service of testing their photo newtonians to be diffraction limited before they ship out. I asked them if they would do a test on just a mirror order and they said yes for an extra $15 on a 6" f/ 6 gso mirror. Sounded great to me to know was not getting a doggie mirror.

Re: Agena Astro certified mirrors
I must be missing something...
You are paying someone to tell you your mirror is at least average?
Do you have a link to this service, I could not find anything.

I did not notice anything specifically detailing testing of stand-alone mirrors purchased from them. But obviously if they have the testing facility they could do so if asked as the OP did. Something I found interesting is that Agena stated in the Q&A section for their mirrors that

Re: Agena Astro certified mirrors
The old icons like Criterion 6" f8 and Edmund 6" were sold under the quality label 'diffraction limited'. Gonna see if new mirrors can meet or beat the oldsters.

Re: Agena Astro certified mirrors
Diffraction limited means different things depending on the metric used to specify. Raleigh, Dawes, or Sparrow? See figure 12 in the following link. https://www.telescope-optics.net/telesc ... wavelength
FWIW I would pay extra for a Zygo interferometer report but not for the report that Agena offers.

Re: Agena Astro certified mirrors
Agena went thru a stack of boxed mirrors and found 2 real good ones, 1/8 wave and 1/10 wave, so I bought the better one. Will report results in 2 weeks against my Edmund 6" f8.

Re: Agena Astro certified mirrors
The 6" f/ 6 with Agena certified mirror is ready to go.
Of course this is Arizona and the skys are not cloudy all nite, no California fire smoke either.
40" long tube and only 12 pounds weight, seems to work good onSV M2 mount.
