Source code is available under GPL license

Upgrade notes: If you already run a previous version please note the following:
Beware this is a full install that may replace some of your file, as a general precaution rename the sample files before to use them. Take a backup before to upgrade!
The AAVSO QuickLook format as changed as a result the program may issue an error message when you try to open an old file. To avoid that erase the content of the quicklook\ folder.

Files in the const\ directory are ephemeris input files by constellation for 16'000 stars from the GCVS. Beware that the origin date for this ephemeris is far from now and the precision may suffer of that. Then this files must be considered as examples or starting point only.

New functions for the version 2.3 :

  • Change format of AAVSO Quicklook.
  • Add AAVSO Chart display.
  • Column are resizable.
  • Minor cosmetic change .
  • New license: GPL .

This program will never exist without the ideas and the patient debugging from Hans-Goran Lindberg.

Take also a look to the Obsvar program by Laurent Corp , it help you to select stars from the AAVSO Bulletin using various criterion. Despite the web page is in French it is possible to use the software in English, look at the bottom of the page.
