So I have had this idea to make a website where astronomers can centrally sell their photography and artwork. In my opinion it would be a great way not only for astronomers to sell and buy their work but also maybe I could add in a chat system for astronomers to have conversations with others around the world. What do you think? Do you have any suggestions? Any comments?

P.S I know the other image buying places exist but that's mostly stock footage and I haven't yet seen a place to centrally buy/sell astrophotography and astronomy art.

Not I but ask the Owl he's much wiser.
