As part of the Institute’s extension program, a total of 653 elementary and high school students were able to attend seven overnight stargazing activities conducted at UP NISMED from December 2013 to March 2014. These sessions were facilitated by members of the Earth Science Workgroup of UP NISMED along with some members of the UP Astronomical Society.

Students from Parañaque Science High School look at Jupiter and its four of its brightest moons.

One of the highlights of the stargazing session is the viewing of night-sky objects through one of the country’s largest telescopes housed at the UP NISMED Observatory. Students as well as their teachers are treated with telescopic views of craters of the moon, Jupiter and four of its brightest moons, Saturn with its beautiful ring system, and a glimpse of the current phase of Venus. Participants also listen to various lectures aligned with the K to 12 Earth and Space Science topics such as constellations, the solar system, comets, and many others. Sessions are conducted at the rooftop of the NISMED building where participants spend the overnight session under the stars.
For further details and reservation, interested parties may contact UP NISMED at telephone no. (02) 928 3545.

With the built-in filter removed and replaced with a Baader UV-IR filter, the camera now has an optimized sensitivity to red, particularly, to H-alpha light. H-alpha light is perceived by the naked eye as deep red hue. It is important to astrophotographers because certain types of nebula emit light at this wavelength. Image taken with a modified Canon 450D and a Sky-Watcher 100ED refractor. To view highest resolution available, click here.

Here is my most recent prototype of a Peltier-cooled Canon 450D DSLR intended for astro-imaging. The intention was to incorporate improvement into each version. In this particular prototype, the camera is housed in a smaller plastic case, making it more compact, lighter, and more sturdy.

Modified Canon 450D DSLR for astro-imaging (August 2014) mounted on a Sky-Watcher 100ED refractor

A custom-fabricated aluminum lens mount is used to allow the modified camera to accept standard Canon lenses and T-adapters. A Baader UV-IR filter is used to optimize sensitivity to H-alpha wavelengths, which also serves as the sealed chamber’s optical window. During operation, sensor temperature drops to 30 degrees C below ambient. To avoid dew from condensing on the optical window, coils of fine nichrome wire were used.

Dimensions: 16 cm x 12 cm x 7 cm case with 7.5 cm x 7 cm x 6 cm heat sink protruding on one side
Weight: approximately 1250 grams
Temperature: up to 30 deg C below ambient
Power supply: 12V 12A for the Peltier module, 8.4V 1.5A for the camera

Test shots and photos taken during construction will be posted soon. Clear skies!
