Thanks for the reply, chx! I finally got the last piece of equipment I needed today and just assembled my poor imitation of your setup. Hope you don't mind me sharing some pictures of it.
I went with an adjustable monopod AKA selfie stick with a 1/4 male screw on top and a 1/4 female screw slot hidden in the bottom.
Which I then stuck a 1/4 male to 1/4 male screw into.
Would really appreciate help/advice if anyone has any, especially in the area of dust management (I've been using cling wrap so far, please don't laugh). The two sides are a bit wobbly at the moment so any advice on how to make it better would be most appreciated!
