This is my first test image of Jupiter using a Vixen R114 telescope on a tracking mount. I used a stack of two 2x Barlows to magnify the image. This is a stack of 2000 frames imaged with an ASI 533 camera and a UV-IR filter.

This is an image of the Sun showing two prominent sunspots AR 3057 (upper right) and AR 3059 (lower left), imaged with a Vixen R114 reflector, ASI 533 MC camera, and a Baader ND 5 solar filter. Never observe or image the Sun without the proper solar filters.

The best time to image and observe Jupiter (and Saturn or any other outer planet) is during opposition, when the planet, as viewed from Earth, is opposite the Sun (as the Sun sets in the west, the planet rises in the east), hence, the term opposition. Two conditions favorable to imaging happen during opposition: (1) Jupiter and Earth will be at their closest point in their orbits around the Sun, thus, making the planet appear largest when observed from Earth, and (2) Since the Sun is opposite Jupiter as viewed from the Earth, the planet is well-illuminated, thus, faster exposures can be taken resulting to sharper images. The Jupiter photo below was taken on August 7, two weeks before the 2021 opposition.
August is particularly rainy (and stormy) in the Philippines, and we seldom get treated with clear skies at this month.

In eyepiece projection, an image is projected onto the camera’s sensor using an eyepiece. In this Saturn photo, I used a 4 in f/9 refractor and a 25 mm eyepiece to project an image onto the sensor of ASI 533 astronomy camera. The magnification of the image depends on the focal length of the telescope, the focal length of the eyepiece, and separation between the eyepiece and the camera’s sensor. While longer telescopes, higher-power eyepieces, and wider separation between the eyepiece and the camera will produce more magnified images, the amount of detail that can be resolved will still depend on the aperture or the diameter of the telescope’s objective mirror or lens.

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.

As Earth and Mars revolve around the Sun, there are instances when these two planets are close to each other, and this happens approximately 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.

This is an image of the Sun showing the sunspot AR 12192, the largest sunspot of the solar cycle 2010 to 2020. This image was taken at solar maximum when the sun is most active during a cycle. It was imaged in October 2014 in Quezon City using a 4 in f/9 refractor and a Baader ND 5 solar filter. Never observe or image the Sun without the proper solar filters.
