- May 3, 2012Hi,
I have an elderly William Yang 100/80, the focuser thread has had to be
adapted to take the TMB flattener. I have the WO STL cone fitting and an
STL 11000. I get flat stars to the extreme of the flat sides, a little
distortion in the corners (about 45 pixels) and some manageable
vignetting again at extremis in the distant corners.
