A simple cross-platform desktop utility for amateur astronomy hobbyists, written in Java. The aim is to provide an easy to use tool to help planning sky observation sessions, suggesting some of the interesting objects you may be able to watch at naked eye, or using amateur equipment (binoculars or small to medium size telescopes) in a given date/time and place.
It would be great to have a nice catalog of some interesting deep space objects, like nebulas, galaxies, double stars. The NGC and Messier catalogs would fit perfectly. However, I have been having some dificulty in setting up JPARSEC for that purpose, even though it includes an extensive API that seems to be able to do it.
Ephemeris calculation can take a long time, especially on slower computers. The interface shouldn't be blocked while threy're being calculated. Instead, it would be better to have the heavy load being performed in a secondary thread, while the main application acts as an observer, listing the objects as soon as threy're ready.
Sometimes, there will be duplicate entries in the Rise/Set/Transit tab (details panel), with date/times within an hour or so. One of those is usually right, but the otther is misleading. It may have something to do with timezones or some ephemeris preparation using JPARSEC.
The application should allow each session plan to be saved for future reference. On one side, it would keep track of session settings, bookmarks and sightings for each session. on the other hand, once we have calculated the list of targets for a given session (which tends to be a time consuming process), there should be no need to take so long again, unless the session settings are changed.
