Richard Wessling at the business end of his
observatory mounted 12 1/2" Buchroeder Tri-Schiefspiegler. Dick reports that
on nights of excellent seeing the images of the moon and planets are
unbelievably good. Nebulae and double stars are equally superb due to
the lack of a secondary obstruction.

Dick's Tri-Schief uses an innovative, rotatable diagonal mirror to
offer a choice of comfortable viewing positions. Schematic
here.
Further information on this design can be found
in Telescope Making #28. Dick's optical prowess was
legendary.

Giovanni Ariot mounted the mirrors for a Buchroeder
design Tri-Schiefspiegler on this provisional structure. The optics for the 300mm
Tri-Schief were given to him by a friend after they were found to have not met
design specifications. With the help of
design software,
Giovanni found the arrangement which yielded an aberration free image.

Alfredo Zanazzo recently completed this 12.5 inch Tri-Schiefspiegler of
Dick Buchroeder's design. While similar to the telescope published in TM #28,
the focuser section differs slightly from that of Richard Wessling's telescope.
The instrument is mounted on a terrace with a roll-away housing. This gives an
unhindered 360 degree view.

"Every year Al has a different telescope on that mount!"
was overheard at AstroFest. This versatile fork mount was presented
as a construction project in "Telescope Making" #30. Plans for the
pictured 6" Kutter Tri-Schiefspiegler can be found in issue #16 of the
same magazine. - Photo courtesy of A.L.Woods
