This forum has many visual observers and the most visual observers have a Dobson. Very simple, nothing beats aperture.
In the Netherlands (and maybe whole Europe) a 20" telescope is a very large telescope. My own telescope is a 16" and large enough for me but what I see in the signatures 28", 32" and even larger are no exception. So maybe it's nice to show a picture of your telescope. Nothing special because most forums have a thread like this but in this case, only Dobs.
I will start with my own telescope, a 16" f-4.5 Dobson.
