433 Eros | January 2012

433 Eros is the first asteroid to be studied with a spacecraft from orbit. Eros was orbited by Near Earth Asteroid Rendezvous several times before touching down in February 2001. This image of Eros was taken during its closest approach to Earth on January 30, 2012 using a 4-in f/9 refractor and a Canon 450D DSLR.

Total Lunar Eclipse | 2011

This photo was taken in December 2011, in Antipolo, Philippines, during a total lunar eclipse. The moon appears red during totality and as it dims (in contrast to a bright full moon), the faint stars surrounding the moon becomes visible!

Transit of Io | November 2011

The Galilean moons may sometimes cross the disc of Jupiter in an event called transit. The satellite (white dot) is usually followed by the shadow (black dot) it casts on Jupiter. In this photo, Jupiter’s moon Io is already exiting, with its shadow still on the disc of the planet. Image taken on November 9, 2011 with a 4-inch f/9 refractor and a Logitech 4000 web camera.

Sky-Watcher Equinox 100 ED

The 2011 Sky-Watcher Equinox 100 ED 4 in f/9 refractor serves as one of my main telescope both for visual observation and astrophotography. The Optical Tube Assembly (OTA) features a 4-in f/9 extra-low dispersion (ED) apochromatic (APO) lens design. It has a 2-inch dual-speed Crayford focuser with a thumbscrew underneath for locking the draw tube. 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.

In 2021, the telescope has been modified and fitted with a DIY reducer, making the telescope faster (from f/9 to f/5.65, at 0.63x ) and also reducing the tube length by 20 cm.
