WHAT IS THIS? The Variable Star Plotter (VSP) is the AAVSO's online chart plotting program
that dynamically plots star charts for any location on the sky, or for any
named object currently in the Variable Star Index (VSX). By creating charts
this way, every chart utilizes the most current data available. Through
the use of unique Chart IDs generated by the Variable Star Plotter, one user
can plot a chart, and another user in different part of the world can plot
an identical chart by simply using the same Chart ID. The Variable
Star Plotter is the tool you should use to create any chart that you would
like to use. WHAT CAN I DO? By entering an object name or its coordinates on the sky, the Variable Star
Plotter can produce a star chart for that object or location, and tailor it
to your specific observing requirements. Many different parameters are adjustable
via this interface, allowing you to get the perfect chart for the job. Customizable
field of view, print resolution, magnitude limit, and orientation can be set for
any chart plotted, or these values can be auto-assigned by selecting from one of
the legacy chart scales familiar to many of our long-time observers. The charts
produced by this tool include comparison star sequences for visual magntitude
estimations. HOW CAN I GET HELP? For detailed instructions on using VSP, consult the
Help Guide . We also
provide a GET method API for
embedding charts in your website or custom software.
