I thought I would put out a link to Royce's website for any of you who don't know who he is, or have never seen his site. Bob makes both professional and amateur optics, and over the last few years has begun to develop and market telescopes as well, specifically Dall-Kirkhams and now 8" & 10" Newts.
is loaded with optical info, articles on theory, design, and scope types, and ATM projects that he's done. Be sure to take a look at the links on the home page for his latest endeavors. Click the "Astronomy" link for products, and be sure to scroll to the bottom of that page for the ATM articles. You have to click the pictures on this page to navigate. There are links everywhere on the site!
Having owned a Zambuto mirror for 6 years, and having a friend of mine who owned a couple Royce mirrors, I can say his Newtonian mirrors are right up there in quality with Carl's, and in fact doing a head-to-head could not see any significant difference between the two.
I have no affiliation at all with Royce, but I've spent hours just reading all the optical information, and professional opinions on his site and in some cases it did have significant impact on my personal optical decisions. Thought you guys might want to have a look.
