Hi Wayne, I enjoyed your last post. Very informative, and it sounds like the mods you are doing will be a great benefit for performance, and user enjoyment.
A shame that there isn't somebody out there with a business of optimizing these SCTs for amateurs. (Kind of like a Telescope speed shop!)
All the techniques you mention have worked well on other designs. The Protostar paper should give a dramatic increase in constrast.
Surely want to hear the follow up when your project is complete, and since you know how your scope performed-behaved before these mods, it will be interesting to hear how your improvements have worked under actual field use.
