Astro-Stuff.com

Astronomical Software created by Joe Novak. Here you will find his AstroClock FX, Double Star Database, and his Saguaro Database 8.1. The AstroClock FX displays the current local & UTC date & time, a calendar, local & Greenwich sidereal times, and the Julian day. The menus include information for the current sun, moon, eclipses, ephemerides for all the planets, minor planets and comets. It also has three timers that can be run independently. I personally think the AstroClock FX is one of the most informative astronomical java applications around. Take the time to check it out yourself. I'm sure most of you will agree.

Ray Cash's Filter Performance

Light Pollution and various "nebula" filters have been around since the late 1970's, and amateurs have been using them ever since to bring out detail (and even some objects) which were difficult to impossible to see before in modest apertures. Which filter best suits your needs? Check out this site.
