Saturation is the primary concern when observing bright targets. The analog-to-digital converter will run out of bit codes at ~28,000 e - pixel -1 in the ATD-GAIN=7 (default) setting, and at ~53,000 e - pixel -1 in the ATD-GAIN=15 setting. ... Hence ATD-GAIN=15 is recommended for targets approaching 28,000 e - pixel -1 . ... For example, stars as bright as V~4.4 can be observed without saturation in F502N using the PC at ATD-GAIN=15 with a 0.11s exposure time. ...

In 2007-2008, the planet Uranus will reach one of its annual equinoxes for the first time since 1966. As a consequence, its five major satellites orbiting in the equatorial plane will undergo a season of mutual eclipses and occultations very similar to the one that Jupiter's Galilean satellites undergo every 6 years. ... Some of these events occur when Uranus is at conjunction, or the satellite is transiting or too close to the limb of the planet. ... Complete table of events . ...
