This ST-237 sure is refined compared with that blasted Toucam. What is a good CHEAP filter wheel assembly that does the job? I dont mind flicking between filters with a thumbwheel. I don't know squat about what threads are on the ST-237, what models of what screw onto it, etc. What works or doesn't work because this is not a ST-237A. Basically, I know nothing. Looking for any guidance. Thanks!
