NGC 7

NGC 7 is a spiral galaxy located in the Sculptor constellation. It was discovered by English astronomer John Herschel in 1834, who was using an 18.7 inch reflector telescope at the time.[4] Astronomer Steve Gottlieb described the galaxy as faint, albeit large, and edge-on from the perspective of the Milky Way; he also noted how the galaxy could only be observed clearly with peripheral vision, not by looking directly at it.[4]

gollark: My own server is a generation behind that, and that was just randomly lying around for free?
gollark: In general.
gollark: A few weeks ago someone on Hackaday apparently had a VAST quantity of batteryless Windows tablets and I wanted some of them for things, but nooooooo, it costs *money* to ship things.
gollark: It annoys me how there are frequently cool free things in places I'm not.
gollark: Bees.
