Welcome to Philippine Astronomy Forum! The ultimate source of information on astronomical discussions on astronomical equipment, observations, events, astrophotography, space programs, astrophysics, astro product reviews, etc. Anyone can join regardless of sex, race, astro affiliation, experience and skill level as long as topic on astronomy and its like are discussed and shared.


I would like to invite all of you to join the ultimate astronomy bulletin board for all interested in astronomy and space regardless of local or international astro community, astro affiliation, race and religion. Feel free to post astro announcements, astro images, astro topic discussions on observation, imaging, astrophysics, general astronomy, etc.







I started doing solar Hydrogen Alpha (Ha) observing and imaging after I got to acquire a low cost Coronado PST-Ha scope. After experimenting with compact digital camera as well as Philips Toucam 740K webcam, I have decided to use monochrome webcam in which the low cost Atik 1HS II monochrome webcam was used by me afterwards. All Ha images were taken by James Kevin Ty using ATK-1 HS II webcam on Coronado Personal Solar Telescope (PST) and 2x barlow lens. Lately in November 2013, ZWO ASI120MM webcam officially replaced my trusty ATIK-1HS2 webcam. Last December 27, 2016, I upgraded my Ha Imaging system from Coronado PST-Ha to Daystar Quark Chromosphere Ha Eyepiece Filter and officially retired my trusty PST.


Whole disk images were taken with Canon 500D DSLR camera on TV-101 refractor with 2x Big Barlow lens and Baader 3.8 solar filter while Close Up images were taken with same camera and telescope setup but with INTES Herschel Wedge. Starting 2010, ATK-1HS II webcam with double stacked 2x barlow lens on INTES Herschel Wedge was used for closeup imaging of the sunspots. Lately in November 2013, ZWO ASI120MM webcam officially replaced my trusty ATIK-1HS2 webcam.

Hi! My name is James Kevin Ty. My interests are in astronomy, photography and travels. I started astronomy when I was still 11 years old. Between that time to around 1982, I settled to learning the constellations, planets and the Moon using just a pair of opera glass. A year later, I saved a little money to buy myself a cheap 20x50 refractor. With this scope, I was able to view the Moon and the bright stars. Eventually, I discovered how bad chromatic aberration ruined the image. I then urged my father to buy me a pair of 16x50 binoculars and I used this to further my observations of the bright star clusters and nebula.

It was in the year 1985 that I joined the Philippine Astronomical Society. During that time, Comet Halley was around to keep us busy. It was then that I bought a 50mm f/16 refractor on an altazimuth mount and I was very excited to view the night sky. When I turned the scope to the planet Saturn, I was very delighted to see the ringed planet! Although the view was only at 100x, the small image of this planet was forever etched into my mind. Next came the famous M42, the Great Orion Nebula, in the constellation of Orion. I was disappointed to know that there was no color in this nebula! I thought that my scope was damaged as it was not showing me what I saw in my astro books. I learned later that the photos in the books were taken with film, which was more sensitive than our naked eye to capture the colors.

During my early stage as a member of the society, Edwin Aguirre and Imelda Joson taught me to be serious in this field and I am thankful for their advice. Both of them are now residing in the U.S. and are working at the Sky & Telescope magazine as associate editor and photo editor respectively. I also met Jun Lao and he gave me some ideas on how to photograph the stars, thus saving me a lot of time to learn and start from scratch. I later developed my skills in astrophotography and had been shooting deep sky objects, comets, planets, eclipses, etc. whenever the weather was clear during weekends. After observing the total solar eclipse in General Santos , Cotabato last March 18, 1988, I got hooked to observing solar eclipses. I lef several PAS eclipse expeditions such as the 1995 expedition at Khon Buri, Nakhon Ratchasima, Thailand; the 1997 expedition at Darhan, Mongolia; the 1998 expedition at Pulau Dayang, Malaysia : the 1999 expedition in Stuttgart, Germany and the 2009 expedition at Wuhan, Hubei Province , China.

In 1998, I decided to setup PHILASTRO-FORUM MAILING LIST so that local amateur astronomers can have a mailing list to discuss and share their astro experiences on any and all astro related topics. I was also responsible for setting up the first PAS webpage that introduced the society to the cyber world also on the same year. The PAS awarded me the Padre Faura Astronomy Medal Award in the year 2000. I was the president of PAS from 1997-2003.

In 2000, I decided to switch to digital astrophotography and started out using a Nikon Coolpix 995 compact digicam to shoot my favorite subject, the Sun, as well as high resolution lunar imaging. After getting acquainted to the compact point and shoot digicam, I made another jump into the Digital Single Lens Reflex (DSLR) camera in 2003 and used it to image deep sky objects such as nebula, galaxies, star clusters as well as solar system objects such as the Moon, the Sun, comets, etc. I was the first one in the country to use the DSLR system in astrophotography. Later, I also added computer color webcam such as the Toucam Pro 740K and the monochrome ATK-1HS II to image the planets as well as for solar and lunar work.

I set up the Astronomical League of the Philippines, Inc (ALP) together with 12 other amateur astronomers in 2003. I am the president of the organization since its inception. I plan to lead another total solar eclipse expedition, specially with members of the ALP, to the May 20, 2012 Annular Solar Eclipse in Xiamen , China as well as to the March 9, 2016 Total Solar Eclipse in Borneo.

I work as a Sales / Account Executive of Gainsway Marketing Corporation and Astra Paper Corporation. I also do professional technical consultancy for schools and other companies on astronomy-related projects and equipment acquisition. For inquiries, I can be reached at .

I have also been a Canon user ever since I started out in astrophotography in 1985. I am still endorsing and recommending the Canon EOS system to my friends because I feel that with Canon, you can always rely on its quality and sharpness. Canon Philippines also supported the ALP July 22, 2009 Total Solar Eclipse Expedition team which I led. They loaned to us several Canon hi-end DSLRs as well as EF L series lenses as a show of support.

In 2010, I also acquired the portable Kenko Sky Memo-R mount and together with the Canon EOS system and lens, I now have a highly portable imaging setup which can be brought to any location without much problem with regards travel weight and space. More importantly, I can still rely on its quality tracking and image quality despite its portability. In 2012, I also will start to do some CCD imaging after acquring a used ATIK 16HR with color filter wheel and narrow band filters to bolster my quest for better deep sky images.
