Orion Telescopes mirrors
- Hello !
This is my first time when I post a message on this group. I`m
build a 8 inch telescope and for this reason I intend to purchase a
besides the fact I have absolutely no practice in grinding one
I have a question for anyone who might answer: how about the 8 in
that Orion Telescopes sells usually ? I want to know something about
quality of those mirrors and I am especially interested if anyone did
tests and which are the results. If someone has a reason to say that
other company that sells 8 in mirrors in the same range of prices and
better quality, please, let me know.
Thank you very much,
A few years ago I bought a 6 inch f/8 mirror from Orion and it
is a very fine, sharp mirror. It shows straight Ronchi lines to the
edge, splits Epsilon Lyra cleanly, shows delicate diffraction rings
in good seeing, and I have used it in excess of 300 power to
advantage on planets.
However, as with any commercial producer of optics, quality is
probably variable. I can only say that the one mirror I bought from
them is quite good.
