I know you are dreaming of 150mm. Go for the binocs realy, low powered wide fields of view and much more portable than a fat refractor on an even heavier mount. I think your 12" dob might be more portable? The only reason I mention it is that after a 12" dob I bought a 120mm F5 achromat. Slightly faster than the F6.5. It only gathers dust and gets pulled out as a mega-guide scope. So promising yet so little used. But if you are eager I'll offer it to you at a discount rate...............
