RE_LISTED -Bargain $950
10 Inch certified 0.992 Strehl primary unused
I bought this mirror about 18 months ago for a planned top rate photography scope. Since then it has been stored in a cool and dry environment in a cellar under the house, unused.
Obviously having a mirror that is certified your not getting a lemon and the few quality mirror manufacturers suggest their mirrors are around 0.95, without certification. This has a strehl ratio of 0.992 which is basically as smooth as it gets short of enlisting a team of scientists. 1/70 RMS vs the Chinese mirrors rating of 1/16 RMS. P-V of 1/14 not to be mistaken for RMS.
[there was a section on Optic Waves website to verify the report, otherwise email them]
Regretful forced sale.
$1500 ono {$950 quick sale}
Mirror is unused since reshape and coat at OWL
