Erika Valdueza on the Galileoscopes at the Manila Observatory

by Erika Valdueza of The Sky Above blog

Genie Lorenzo invited me to join her and six Ateneo undergraduate students in assembling Galileoscopes owned by the Manila Observatory.

I brought Eddie (my cute little red Astroscan telescope) with me and used it to show the moon and Jupiter to the students; while Genie demonstrated to them how to use the Galileoscope (she has already completed one Galileoscope).  According to her, the Galileoscope included two eyepieces and a barlow that could magnify objects by 17x and 50x. All of us were given a chance to see the moon and Jupiter using this telescope. I was amazed with its capacity to clearly resolve the moon’s craters and Jupiter’s bands and moons despite its small aperture.

After a short introduction about the telescope and a review of optics, we started building our Galileoscope. It took us more than hour to finish and we honestly had a hard time building it. The manual’s instructions were a bit confusing and the pieces looked all the same. We also don’t recommend it to elementary students who still lack basic background in Physics and Optics. Therefore, building a Galileoscope should be for students in secondary and tertiary levels.

To see the step-by-step procedure, you may watch this video from Youtube.  Genie took our pictures while we were busy figuring out how to put together the Galileoscope. In the end, all of us were successful and immediately used the telescope for stargazing. (visit Erika’s blog post for the You Tube links here.)

To the stars!

Ateneo Physics Notes:

The students are members of the League of Ateneo Physicists (LeAPS), the Ateneo Physics students’ organization.  Genevieve Lorenzo (BS Ps ’98, MS ECE ‘2010) is a researcher at the Air Quality Division of Manila Observatory. Erika Valdueza is a former researcher at the Solid Earth Dynamics of Manila Observatory.
