TMB Paragon 40mm
This is an interesting eyepiece, filling a niche between the premium priced widefields that are better corrected for use in fast telescopes (f/6 and faster) and the many inexpensive offerings that try to offer low power, widefield views, but often fail. I use my 40mm Paragon mostly as a finder eyepiece for DSO's and to get full views of the moon. I enjoy using it in both my f/6.9 80mm refractor and my f/8 6" reflector. The views are sharp, except for the last 5-10% of the FOV. In these telescopes it is probably the best low power eyepiece. Of course when I get my fast dob I will start saving for a parachorr and some naglers.
