I thought I could control this passion if I read more on astronomy and so I took a different course and started reading biographies. From Isaac Newton to Nicolas Copernicus to Galileo, I have tried to feed my love for the skies by reading the life stories of this great men and women. But the more I opened pages the more I found I wanted to know more – and more I read, libraries I visited,...

The Bradstreet Observatory consists of twin 14.5-foot diameter galvaluminum Ash Domes, able to rotate 360 degrees. The shutters are designed to slide up behind the dome, with a lower shutter that lowers downward, allowing the observer to see from the horizon to the zenith. The domes are controllable not only from within the dome but also remotely from the Russell Control Room. The azimuth of...

25 years ago I released (as shareware) the first version of my Earth Centered Universe Planetarium/Telescope Control software. At the time, it was the first such program in the world available for the (new) Microsoft Windows 3.0 operating system. It all began about 6 months earlier when I was challenged by my "mac" astronomy friends to write something as good as the Voyager software, so I did!...

Overall this camera was an unexpected surprise. CMOS technology has really come on leaps and bounds in recent years and this is great news for the consumer. Its capability and performance go far beyond its modest price tag and when all factors are taken into account it is quite possibly the best camera presently available to those interested in imaging the Moon and planets. As amateur...

Second release in a month! (By the skin of my teeth 🙂 That does mean there aren’t too many new features in this one. The main changes are partial support for the Celestron Neximage cameras and potentially Imaging Source USB2 CMOS cameras, support for the cooler controls in ZWO ASI cameras and support for Point Grey GigE cameras. There are also bugfixes for the ARM7 build, Point Grey IIDC...

Explanation: Look opposite the Sun in the sky tonight and you'll see Mars at its brightest. Also within days of its closest approach Mars rises at sunset, near its brightest and best for telescopic observers too, except for the dust storm still blanketing the Red Planet. These two Hubble Space Telescope images compare Mars' appearance near its 2016 and 2018 oppositions. In 2016 the martian...

Computes and tabulates the dates of visibility phenomena: for planets and stars first and last visibility, acronychal rising and cosmical setting; for the moon first and last visibility, and the tables provide much supplementary information. These phenomena are very useful for historical purposes. Since the computation of visibility phenomena is complex and uncertain, alternate methods are...
