The results are excellent. The units that you sent to me meet every criterion for a well corrected Triplet of this design. Furthermore, the lenses themselves have no spots or small area defects that could degrade image quality. Resolution to 1.14 arc sec was measured. Uniform diffraction pattern.
Color correction exceeds achromats.
The completed scope was star tested under fair sky conditions. The telescope yields sharp edge to edge images across a 2.5 degree field of view. Lunar edge confirms a well color corrected system, even at very high magnifications. Overall contrast is excellent for extended objects. This system will be an excellent photographic lens as well as a CCD imaging system.
