Object Visibility

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).

Finder Charts

This service provides online access to digitised optical Schmidt plates from the STScI Digitised Sky Surveys DSS and DSS-II. The Digitized Sky Surveys were produced at the Space Telescope Science Institute under U.S. Government grant NAG W-2166. The images of these surveys are based on photographic data obtained using the Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope. The plates were processed into the present compressed digital form with the permission of these institutions. The data is produced by the University of Leicester ~ LEDAS

Exoplanets

The Extrasolar Planets Encyclopaedia is a working tool providing all the latest detections and data announced by professional astronomers, useful to facilitate progress in exoplanetology. The encyclopedia, started in 1995, is updated daily by Jean Schneider from the Paris Observatory ~ Encyclopedia
