I have another round of super high performance parabolic mirrors from our workshop. Three mirrors:

Mirror #1: 8" f7.6 - 1/22.49 wave p-v, .994 Strehl Ratio, $450.00
Mirror #2: 8" f7.6 - 1/33.4 wave p-v, .998 Strehl Ratio, $500.00
Mirror #3: 10" f6.0 - 1/36.65 wave p-v, ,997 Strehl Ratio, $400.00<-

Read on for more information!

Mirrors are currently uncoated and will be sold as is or can be coated for an additional fee.

Substrate is Pyrex for all mirrors.

Mirror #1 & #2 are NEW. Mirror #3 is a re-figured blank.

Mirror #1 Data:

Mirror Thickness 1.375"
Clear Aperature 7.876"
Focal Length 60.250"
F ratio 7.651
RMS Wavefront Error 1/166.67
P-V WaveFront Error 1/22.49
Strehl Ratio 0.994

Mirror #2 Data:

Mirror Thickness 1.375"
Clear Aperature 7.875"
Focal Length 60.250"
F ratio 7.651
RMS Wavefront Error 1/261.90
P-V WaveFront Error 1/33.40
Strehl Ratio 0.998

Mirror #3 Data: (Why is this mirror priced so low?? See below)

Mirror Thickness 2"
Clear Aperature 9.840"
Focal Length 58.875"
F ratio 5.983
RMS Wavefront Error 1/220.00
P-V WaveFront Error 1/36.65
Strehl Ratio 0.997

O.K. You can see that mirror #3 (the 10") has an outrageous figure, however this is a refigured mirror who's blank was not well taken care of. The blank has several chips out of the sides and back of the blank as well as a small scratch in the face. These "defects" only affect the ego & resale value and not the performance. A new mirror of this quality would easily sell for $800.00 plus.

This mirror provides a way for someone to get into a super 10" scope for less than a fortune! Steal it for $400.00!!

All mirrors come with a certification report.

Email for further information or to claim your new mirror!

Thanks much!
