Hi, Greetings from Singapore!
I have with me a 12.5" f/5 Zambuto mirror taken from a Mag1 12.5" Portaball telescope (mirror s/n: Mag1-12.5-078) with complete certification. The mirror is from the time when Zambuto still produce the complete wavefront documentation. It has recently been recoated at the current Zambuto coater (Nova optics - Steve Dodds).
Here's the complete statistics of the mirror:
Relative Transverse Aberration 0.32
Peak to Valley Wavefront 1/ 23.5
Wavefront RMS 1/ 63
Strehl Ratio 0.990
Currently I have no time to complete this project and looking to sell the mirror for AUD1900.00 plus shipping.
Please private message or email me if you have any queries.
thanks and clear skies,
Arief
