Clear nights are few and far between here in Florida lately, so I decided to try out telescope.live. This is about 100 minutes' worth of RGB data from their telescope in Australia on the Coalsack, looking into the plane the Milky Way from the Southern hemisphere.

Telescope.live is a relatively new service, and to be honest they are still working out some kinks. But it's an interesting way to image stuff you could never see from your own location, and keep your processing skills up during cloudy seasons.
