Galileoscopes at the Manila Observatory
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.

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.
To the stars!
