Sky Map
via the Bad Astronomer, Sky Map is like google maps but for the night sky.
Its got a few quirks with it, if you scroll the map a large distance it thinks it needs to load all of the images again instead of just the new ones. It also doesn’t contain any solar system objects. Quirks aside, its a pretty cool web app.
Sky-map dealing with spherical projection on plane. If you move far enough, it has to relocate zenith point that require all images to be re-drawn – no way around. Cylindrical projection, that commonly used for geographical maps, is not acceptable, because it extremely distort poles. Second one is fair – sky-map does not show solar objects yet.
Anyway thank you for the review.

Thanks for taking the time to address my review, Sergei. That is a good explanation for the redrawing I saw.
