Re: Manfrotto tripod
I'll add this - make sure you get something that will go high enough for you, if you're planning on using it standing a lot.
The 190 tripod maxes out at 57.5" . Using it with a 322rc2 head, combined with the straight style eyepiece on the USO, it's ends up being just a couple inches short of being comfortable for a 6'+ person, when standing.
Going to either a 055 series tripod or a 3265 verticle style head would resolve the issue for me. With an angled eyepiece scope, the 190 series with the 322rc2 head is perfectly fine.
