I posted the CDK12 review last week.

Also tested the PW CDK 0.66x reducer with good results.

Currently imaging at f/5.3 with the CDK12 and the APS-C chip unguided.

The QHY600 full frame is due this week and the upcoming CDK14 should be here in January 2022. 

I will test the reducer again with the CDK14 and a full frame chip.
