My interest is primarily visual lunar/planetary field, I use various Orthoscopics which seem to be the best for this purpose, but I also use Tak 7.5 and 24mm as palnetary eyepieces, the 7.5 despite a slight warm tint is one of my favorites with my 6" apo and with a binoviewer. The next one is 12.5mm, somehow I feel that Tak has left a very important fl. untapped in this series, thus the 10mm LE, I wonder if we will ever see one.
