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).
