This should be the most popular long focal length /
Low-Power eyepiece, especially for the 7" MaK's, and 8~9.25" SCT's.  The 50mm 2 inch Super-Plossl eyepiece is
a superb Low-Power eyepiece with fantastic edge to edge sharpness and
contrast ! Even on most 8~10 inch Newtonians this eyepiece yields stunning contrast and super-flat images.

 Here is an AWESOME  Super-Plossl 5-element design eyepiece that will absolutely amaze you with ULTRA-sharpness  and superb contrast and performance at a fraction of what you would expect to pay.

Russell Optics makes this 2
inch ,  50mm Wide-Field Plossl  with SUPERIOR multi-coated lenses , 25mm eye relief and is threaded for standard 2 inch filters.

Russell Optics is Now the ONLY manufacturer that we know of that makes the Long focal length eyepieces anymore !!

you ask ?? It is simple really.... The demand from astronomers that
want eyepieces over 40mm in focal length is not as big of a market place
for the "Big-Guys" to invest their time and money.

here at Russell Optics however want to serve the astronomers that still
wants the low-power, super-flat FOV even if it means making an eyepiece
that only a few dedicated people still wish for !

note.....on Telescopes with a central obstruction ( Like SCT's,
Maksutov's, or Newtonians ) a basic rule of thumb is to keep the
magnification above about 35x. Once you go below 35x you stand a chance
of losing contrast. If your obstruction is larger than 25% of the
primary you could also get a "ghost" image of that secondary mirror.

you have any questions or concerns I will gladly help you make the
correct choice for your particular choice. Since Ebay no longer allows
phone numbers or addresses in the ads ( I have NO idea how all the
others are getting away with it ) You can get ahold of me at Russell
Optics & Machine in Arizona , or try clicking the blue & red
"ME" link next to our feedback.

Beautiful fully-multi-coated lenses  yield superb contrast and excellent sharpness and detail. There
is really NO OTHER manufacturer that offers this  masterpiece, but *if
they ever did, the cost would be  3 to 4 time our price !!!
