My impression through my My new grinding machine, polishing a 25 inch [cm] diameter mirror. An amateur creating a new telescope design has a formidable threshold to overcome: The quality and size of the optics and the ease of transporting the telescope to dark skies means the greatest observing experience in human history. I dug out my old notes on my secondary size study from the 's using my wonderful 14 inch telescope. The IFN near 39 Bootis is quite bright though large and ill-defined.
The mirror has to be carefully ground , polished and figured to an extremely accurate shape, usually a paraboloid. I wrote a page describing my effort. If the mirror is spherical but with defects such as bumps or depressions, the defects appear greatly magnified in height. It is a master piece.
Therefore, the design, size, and construction of the telescopes vary as well. I finished the spider and diffraction designer for my Newtonian Designer web application. I thought high clouds were passing through until I realized that I was seeing very faint extensions of the Milky Way! I investigate the tilt tracking table and hexapod mount with a fellow tilter.
Finally, the precision refractory molds for slumping the 42 inch mirrors in the kiln are proving too thin. The equipment most amateurs use to test the shape of the mirrors, a Foucault knife-edge test , is, like the tools used to create the surface, simple to fabricate. The glow of the galaxy nicely encompassed M By following the procedure outlined, a tool can be made for any size disk, inexpensively, and with very little effort. Volume 3, Subjects covered: Compare to my M64 sketch. I call this 'Richest Galaxy Observing'.
