Observing ReportsAAVSO Send your variable star reports to the American Association of Variable Star Observers AL The Astronomical League has over a dozen observing clubs ALPO Send lunar and planetary reports Association of Lunar and Planetary Observers AMS Send meteor reports to the American Meteor Society IOTA Send occultation reports to the International Occultation Timing Association NAMN Send meteor reports to the North American Meteor Network Small Telescope Observations What to See with a Small Telescope. An attempt to answer this question by publishing observing reports from astronomers who use telescopes that are 150mm or smaller.
Observing Program AidsPrograms to Optimize Observing Using STARMULT 1.1 (Courtesy Isaac Newton Group of Telescopes)
- Table of Optimum Observing Parameters: Includes Optimum day of the year, Rise time (above the specified elevation), Culmination time, useful Hours (above the specified elevation), Set time (below the specified elevation), Moon distance (deg.) and Moon illumination (%).
- Altitudes: gives altitudes at middle-dark-time and hours spent above a selected altitude for a list of objects throughout a specified year. Useful information to optimize your observing is also provided, such as airmass, distance from the Moon and days of Full Moon.
- Altitude vs. Time Plot: Plots altitudes against time for a list of objects. Useful information to optimize your observing is also provided, such as Sun and Moon parameters, airmass, sidereal time and, if very different from UT, the solar time of the proper Time Zone.
