I bought this on CN last year but the project never launched and I have since retired from ATM.
I'm selling it reduced because I never observed with it but hope someone else will.
I have attached the test results from the original CN ad where it was advertised with the following:
***
"Excellent 8-inch mirror, f/6.85, focal length 54.875 inches
( P-V Wavefront Error 1/7.53 )
( Strehl Ratio 0.947 )
No trace of turned edge.
Center marked for collimation
This is an excellent general purpose 8-inch mirror. Gives excellent planetary definition and deep sky performance.
Coating has some small blemishes. Coating is not pristine, but these small spots do not affect overall performance."
****
CONUS only, I will cover Paypal fee and shipping.
