Solar Shades

solar_shades
Specialized shades for viewing the Sun during solar eclipses. Without proper filters, looking directly at the Sun will result to permanent eye damage.

I have just finished making a couple of solar shades for the upcoming solar eclipse on March 9, 2016. To learn more about the specialized safety filter I used in this solar shade and what other low-cost alternative can be used, click here.

How to Construct a Filter Cell

Observing the sun requires a special type of protective filter called a solar filter. Such filters work by passing sunlight through specialized layer of metal, placed in between layers of glass or plastic film. Solar filters block more than 99.99% of sunlight, and must be placed on top of the telescope’s objective (on the main aperture of the telescope) to reduce the sunlight’s intensity before it gets focused by the telescope. Without a solar filter, sunlight’s intensity will be high enough to cause loss of vision and damage to equipment.

Observing and imaging the sun require a solar filter

To learn how to construct a mounting frame (also called a filter cell) for a solar filter, which will help protect the delicate film and allow safe viewing (and imaging) of the sun, click here.

Venus Transit 2012

The Venus Transit of 2012 is considered as the rarest predictable astronomical event. It is so rare that one person can only observe it for a maximum of 2 times in his or her lifetime. It occurs when the Sun, the planet Venus, and the Earth are in perfect alignment with each other. As viewed from the Earth, Venus appears as a black dot moving across the disc of the Sun.

Second Contact occurred at around 6:30 am, as measured by our timing equipment. This measurement is consistent with the calculations of Mr. Bamm Gabriana. Photo Credit: Anthony Urbano, Ezekiel Rodriguez, Beb Jansen Poricallan, Carlo Ray Selabao, Criselda Roque

Sunset March 12, 2013

gallery_sunset_march122013
Sunset at Manila Bay on March 12, 2013 while waiting for comet Pan-STARRS, taken with a Canon 450D DSLR, 50 mm lens, f/22, ISO 100, 1/4000 sec exposure. While solar filters are not required in taking images of sunrises and sunsets, safety precautions must be observed to avoid permanent eye damage: never look directly at the Sun through the camera’s optical view finder; use the ‘Live-View’ function instead.
