DIY power supply adapter for Canon 1100D

EtenyLeave a comment

In astrophotography where DSLRs are expected to take images continuously for several hours, spending on expensive spare DSLR batteries may not be the best investment. The DIY modification below shows how I used an old DSLR battery and a DC adapter as an alternative way of powering your DSLR during an overnight stargazing event.

DIY power adapter for powering DSLRs from an external 12V battery. A voltage regulator called ‘7808’ is used to ensure that the voltage output remains at 8 V.

Stargazing in Antipolo

EtenyLeave a comment

As you move away from a city, the glaring lights that cause light pollution are greatly diminished, allowing one to see fainter stars. In recent years, Antipolo has been of a particular interest to astronomy enthusiasts, perhaps this is due to its relatively dark skies and short travel distance from Manila. A popular destination is Seven Suites Hotel Observatory, which opened in 1998. This hotel allows you to conduct stargazing sessions in the comforts of a hotel. Another popular site is intended for the outdoor type who wants to setup tents in a camp site–the Big Handy’s Grounds.

For about 7 years now, me and my colleagues–a rather tight group (less than ten people) have been taking astronomical photos from a less known but equally capable site in Antipolo. It has become our favorite observing site because it is safe, it has power (for our laptops, telescopes, and cameras), there are facilities that we can use, and of course, we can arrange exclusive access to the place.

Basically, any place in Antipolo, be it a resort, a campsite, or a full-fledged hotel, should offer skies dark enough for visual and astronomical photography work. If you are into astronomy, find a spot there and start observing!

Celestron Travel Scope 70

EtenyLeave a comment

The Celestron Travel Scope 70 is a small telescope designed for viewing distant land-based targets (such as birds and trees) and for casual astronomical observations. While many enthusiasts would purchase this telescope perhaps as a grab-and-go telescope, my intention for acquiring one is different since I intend to use it as a guide scope for my autoguider setup (if you want to know more about it, click here).

I have been using this telescope for several months now, and I believe I now have a firm grasp of what it can and cannot do, and its advantages and disadvantages. In this article, I intend to share some of my insights about the Celestron Travel Scope 70, particularly in the context of visual observation and astrophotography.

Big Dipper and Mayon Volcano

Eteny3 Comments

I have always wondered how big Mayon volcano would be when framed against the night sky, as viewed from an easily accessible location such as Legazpi City. The photo below shows the apparent altitude (or its height measured in degrees) of Mayon, with the Big Dipper asterism framed in the background to provide a sense of scale.
