[1] WikiSky is designed, in part, as a wiki.Users can edit information about different stars by writing articles, adding Internet links, uploading images, or creating a special interest group for a specific task.

Once the images are aligned they can be saved to collections for later viewing and sharing. The layer manager can be used to add vector or image data to planet surfaces or in orbit. [11]

Typical exposure times range from 15 minutes to many hours long, depending on the desired length of the star trail arcs for the image. [7] Even though star trail pictures are created under low-light conditions, long exposure times allow fast films, such as ISO 200 and ISO 400. [6] Wide-apertures, such as f/5.6 and f/4, are recommended for star ...
