- Calendar Generator
Generates Monthly calendar for every desired place and time. Includes: Moon phase, Julian day, sidereal time, Sun Rise/Set, Moon Rise/Set and Moon equatorial position.
- Moon and Sun Rise and Set
Calculates the Moon and Sun rise and set times given the date and the place.
- Signal to Noise Calculator
Given the instrument zeropoint, extinction coefficient, gain, read out noise, bias level, sky brightness, etc. estimate the exposure time needed to image a point like source with a given magnitude and a given S/N.
- Monthly skymaps for Israel
Generate monthly maps of the sky visible from Israel. Includes stars to magnitude 4.5, with their spectral type coded in color (without planets).
- Almanac - Daily ephemerids
Daily ephemerids for Israel. Moon and Sun location, rise and set, location of the planets, skymaps for different hours.
- Daily moonphases
Daily Moonrise, Moonset and Moonphase for Israel. Accurate times of moon phases.
- Object Visibility
Plot object visibility and distance to the moon. Need to enter the Wise Observatory East Longitude, Latitude, and Altitude, which are 34.76, 30.6, and 875.
