I have the same set-up as jjhunter, but use the extender all the time, it really is amazing when setup with 20-60 eyepiece and 95 obj when digiscoping…. have used many different tripods because of the weight of the unit, but keep going back to Outdoorsman when having to pack, Slik when not packing. Slik works good, just heavy, have used Slik for Doctor 30x80's for years before Swarovski BTX came out....
You won't beat the Swarovski BTX IMO.
