The full NGC/IC catalog, ~12,000 objects deep
The whole NGC/IC catalog is here, each object drawn with the classic chart symbol and color-coded by type, clickable to identify. The Messier and NGC showpieces, from the Andromeda Galaxy to the Orion Nebula and the Pleiades, carry real survey photography, and a sky-conforming deep-zoom pulls in imagery aligned to the actual sky as you push in closer. Search by NGC, IC or Messier number or common name and fly straight there.
From the Milky Way to the cosmic web
Zooming out doesn't stop at our galaxy. Past it lie 43,530 real galaxies from the 2MASS Redshift Survey at their true positions, and eventually the cosmic microwave background boundary, all reachable in one continuous pull-back. There's a whole page about it: fly through the cosmic web.
