Object Visibility – STARALT

Staralt is a program that shows the observability of objects in various ways: either you can plot altitude against time for a particular night (Staralt), or plot the path of your objects across the sky for a particular night (Startrack), or plot how altitude changes over a year (Starobs), or get a table with the best observing date for each object (Starmult). For further information, click on the "help" button at the bottom of the page.

Vignetting at low elevation

The WHT lower dome shutter is currently (and probably until July 2013) out of action, and observations at elevation <25 deg will be vignetted (plot).

or specify own site: "East_Longitude(deg) Latitude(deg) [Altitude(m)]"
Coordinates Available formats: [name] hh mm ss ±dd mm ss ; [name] hh:mm:ss ±dd:mm:ss ; [name] ddd.ddd dd.ddd. [name] must be a single word with no dots.
