Transit of Callisto | April 2011

Jupiter’s moon Callisto appearing as a dark dot against the bright planet’s disc, was seen transiting Jupiter on April 4, 2021, 5 am local time. Another Jupiter’s moon, Io, the cloud bands, and the great red spot, are also visible in this photo. Very bad seeing conditions made it difficult to capture sharper views of the planet.

Callisto’s transit was captured with a 4 in f/9 refractor and a dash camera, processed in IRIS.

Jupiter | April 2021

Jupiter is now visible in the early morning sky. It is still low in the horizon making it very difficult to image. Jupiter’s cloud bands are visible in this photo.

Jupiter imaged with a 4 inch f/9 refractor and an SPC900NC web camera, processed in IRIS.

Earthshine | March 2021

I’ve observed and photographed the moon’s earthshine, in which the crescent moon’s darker surface is illuminated not directly by the Sun, but by sunlight reflected off the Earth.

How To Take Photos of the Milky Way

The Milky Way is most prominent in the sky during months of March to May each year, visible to the unaided eye in the southeastern horizon at around 2 to 3 am. The maps below show how the Milky Way would look like in the Philippine sky at various times of the year. 

January, February | Southeast, 5 am
March, April, May | South, 2 am
June, July, August, September | South, 12 mn
October, November | Southwest, 7 pm

Dashcam as Planetary Camera

I repurposed my old dash camera (Polaroid N302) as a planetary camera. The lens was removed and replaced with a webcam-to-telescope adapter and then mounted on to a 4 in diameter, 900 mm focal length Sky-Watcher 100ED telescope on a tracking mount.

A pair of 2x Barlows were used to further magnify the image (3600 mm effective focal length). To watch a video about this dashcam planetary camera, click here.

Venus | July 2020

Among all the planets, Venus is the brightest. It is usually seen an hour before sunrise, or an hour after sunset. The phases of Venus may be observed and photographed with a small telescope. This image of the crescent Venus was taken with a Canon 1100D and a 4 inch f/9 refractor.

Veil Nebula in OIII

A narrowband filter such as an Oxygen III (OIII) filter inserted along the optical train lets the light from the stars and nebula pass through, but block out everything else, particularly light pollution. This image was taken in Quezon City with a Canon 450D and a 4 inch f/9 refractor, exposed for 30 minutes at ISO 1600, tracked and guided.

Milky Way | Bolinao

We went on a road trip to Bolinao, Pangasinan. At daytime, we explored the beaches and tourist spots and at night, we stargazed and imaged the Milky Way! With a sky that is relatively dark, I was able to take a photo of the Milky Way with the resort as foreground.

Saturn | May 8, 2016

Saturn almost always impresses anyone who looks at it through a telescope. When compared to Jupiter or Venus, Saturn is relatively dim, making it difficult to photograph when using a small telescope.

Exposures as slow as 1/15 second was used to capture this image. I used an eyepiece to project an image of Saturn on to a Logitech 4000 web camera’s sensor. The division in Saturn’s ring and the cloud bands are visible in this photo. Image processed in IRIS.

Mars | May 2016

As Earth and Mars revolve around the Sun, there are instances when these two planets are close to each other, and this happens every 2 years. This is the time when Mars is best photographed and this is also the window when spacecrafts are sent to Mars! This image of Mars was taken during one of its closest approaches to Earth, revealing the dark and light patches on its surface, along with white clouds in its atmosphere. I used an SPC900NC web camera to capture this image. Image processed in IRIS.

Jupiter | March 2016

Planets are particularly difficult to image, especially if using a small 4-inch telescope. You need to image at very long focal lengths to magnify and zoom in to the planet and a large aperture to reveal finer details. To capture this image of Jupiter, I had to use an eyepiece to project an image on to an SPC900NC web camera’s sensor. Precise tracking is essential to keep the planet’s image in frame for more accurate registering and stacking of images.

Jupiter’s Great Red Spot and the cloud bands of alternating dark and light color, are visible in the photo. Image processed in IRIS.
