How and when did The Night Sky Atlas get started?
It got started after some failed attempts at finding software for conveniently placing common sky object labels on astrophotos. That was towards the end of 2007, and it led to testing ways of easily labeling photos of the night sky. After a few months, with a few more features, the results started looking like a complete atlas and it was made into a website as such. The name “The Night Sky Atlas” was found to be unused by anything else and so it was named.
