Introducing the patent pending McKerron-Newtonian telescope
design, which I expect, will put my own great country, Canada, on the map along with the Russians
for optical excellence and innovation.
With the extreme high quality of my method for producing true
parabolic reflectors, - I can afford the luxury of incorporating a "Transparent Spider" into my
designs. This will eliminate the need for frequent collimating common to most Newtonian designs.
Yes. I am aware that Schmidt-Newtonians, and Maksutov-Newtonians do the same, but they use inferior
spherical optics, - where my offering provides all the benefits of true parabolic performance
without coma error. My true parabolic reflectors eliminate the coma error produced by approximated parabolic
reflectors, while my Transparent Spider eliminates the coma error due to poor collimation.
My "Transparent Spider" is really a "Neutral Corrector Plate" with a very low Peak-to-Valley
Wavefront Error. In fact the Total System P - V Wavefront Error including the Main Mirror,
Transparent Spider, and Secondary Mirror combined, - is still a whole order of magnitude better
than "Diffraction Limited Optics".
The fine figure of my main mirror is protected by the mirror's
extra thickness
which maintains a more even distribution of the wavefront deformations across the mirror's surface than
a flotation cell would.
