Mat, you comments are duly noted. Didn't think about the focal lengths/ratio issue and you've made a good point. The 2" eyepiece in my possession has a 52 degree field and was excellent in the f/10, but it might not be so good at f4.5. DAMN - now I have to build the scope to check it out (thanks Mat ;-)) I receive Orion's catalog every few months and so took the time to wander through it. My wish list totals over $500 and my pie-in-the-sky wish list totals over $1,500. They sell Tele vue and the 14mm (I typed 14" first, now that would have be a mind boggling eye piece) radian is available for $240. Of interest was a solar filter for telescopes that fits over the front. I t is of glass with an aluminum cell and screws to fit tight (that's always been a worry of mine). If the picture is correct, it gives a "yellow-orange" sun (my mylar filter gives a blue sun), which would be nice to have - to fit a C8 - $104. Al so, there are "pairs" of these filters to fit binos (10x50 -$87) Also a "shorty" 2x Barlow for less than $40 and and 3X barlow for less than $50. They also have 2" barlows to fit a dobsonian. An attractive "deluxe" filter set for planetary study, including a "light pollution" filter and adjustable polarizing filter for about $100. I got such a basic set from Celestron many years ago and was extremely disappointed. I noted the Q70 eyepieces with relish, but now Mat's comments have tempered my zeal. I could go on and on. Now I can't buy anything until the dob is built just in case I get bad eyepieces --- thank's Mat (grrrrrr grin ).
