Transit of Io 2011

When in opposition, the 4 bright Jovian satellites may cross the disc of its parent planet in an event called transit. The satellite (white dot) is usually followed by the shadow (black dot) it casts on Jupiter. In this photo, Io is already exiting, with its shadow still on the disc of the planet. Image taken with a Logitech 4000 web camera through prime focus imaging setup.

Sky-Watcher Equinox 100 ED

The Sky-Watcher Equinox 100 ED 4 in f/9 refractor serves as my main telescope both for visual observation and astrophotography. The telescope comes with aluminum-lined wooden carrying case. It is supplied with two eyepieces: 25 mm and 5 mm. Supplied also is a 90-degree 2-inch diagonal mirror and an 8 by 50 finder scope.

The Optical Tube Assembly (OTA) features a 4-in f/9 extra-low dispersion (ED) apochromatic (APO) lens design. It has a 2-inch/1-inch dual-speed Crayford focuser with a thumbscrew underneath for locking the draw tube once focus is achieved.
