We have started to order components, we plan to order PCB fabrication and mounting for two telescopes as soon as we get feedback from you.
Time is short, so please react quickly.
While we are not commenting on the schematics, there is an important point we want to underline. The last stage of the linear chain is there to accommodate a fourth pole in the filter, should this prove useful. If you think we can definitely get rid of it, please tell us ASAP, we are still in time in the next few days.
