I am selling a fantastic Gutekunst compact ADC here.
It was ordered directly from Martin Gutekunst, ordered in late 2023 and arrived in early 2024.
It is practically brand new; I have used it exactly four times.
In addition to the ADC, I can also sell ( for an extra cost ) : 2 dovetails with female T2 threads and 2 dovetails with male T2 threads , these were ordered separately from Martin and are also brand new. (This would allow for a quick change if you have other optical systems or use the equipment on different telescopes.)
Everything is complete, exactly as Martin ships it.
I am providing the ADC invoice and the invoice for the adapters.
Best regards,
Guillaume.
«Dear Guillaume,
Great it would be a pity if you miss to observe Jupter ans Saturn without a good ADC. I hope You will really enjoy the ADC. I will send the ADC #108 in the next days.
Of course every ADC is assembled and tested by myself in my optical lab. By the way all parts are from Germany mechanics and optics.
I have added the test report from ADC#108. It is exceptional good with 1/14 lambda PV and more important 1/130 lambda RMS wavefront leading to 99,8% Strehl.
Measured in autocollimation at F50 the precision is about 0.1% strehlvalue. So You can believe these data. (By the way I have cross checked my measurements with a colleague who use an Michelson interferometer and we got the same result within 0.1 % strehlvalue….»
