Hi Matt, I have two Televue refractors and Canon image stabilised 12x36 binoculars. Binocs are nice for scanning but of course fixed in magnification. The Pronto is very convenient to carry and great for wide views, its on a small Unitron 114 alt/az tripod left set up in the house. The NP101 is nice for wide field or high power and is mounted on a large Unitron alt/az mount and can still be carried all set up. Your mounted 6" mak would compare in portability to the NP101. Here or Ebay are perhaps the best options for selling. In selling your gear, you will take a loss. The market is flooded with new cheap telescopes. Do you really think the small gain is worth the expense
