Perhaps an #astrodon question, but is there a good hashtag for aftermarket astronomy gear?
Specifically, I'm in search of a clockwork RA drive for a lowly old Mead tripod, and I know (a) they must exist and (b) might be cast to The Drawer when something electronic was acquired, only I'm specifically wanting to avoid anything with batteries 😅

J'ai beau être astronome amateur, je connais mal les nuages noctiluques ou noctulescents. On est en juin, il est 23h50, 48° de latitude nord, je regarde Š l'horizon nord-ouest, et je vois ces nuages. Est-ce que c'en sont? #astronomie #astrodon
