Imaging Planets Using Webcams

Two of the most popular webcams used in astrophotography: Logitech Pro 4000 (left) and Philips SPC900NC (right).

The modest web camera (or webcam) quickly gained interest among amateur astronomers and is now considered as the equipment of choice for planetary imaging because it has two characteristics that are very much useful in astrophotography: (1) its lens can be removed much like the lens of a DSLR, making it possible to easily connect the webcam with any telescope and (2) it can record a huge number of still frames even in a short span of time (1-2 minutes), a feature particularly useful in a post-processing technique called registering and stacking.

Photo of Saturn taken on May 8, 2016. Image captured through eyepiece projection method with a 4-in f/9 refractor, UV-IR filter, a 5 mm eyepiece, and a Logitech Pro 4000 web camera. Processed using AutoStakkert and Registax.

In this article, I intend to describe how to image planets using a web camera as the main imaging device and then provide a brief overview of the post-processing technique. Read more.

Moons of Saturn imaged last April 9, 2012, 2:04 am local time. From left to right: Hyperion, Tethys, Dione, Enceladus, Rhea, Iapetus, and Titan (one more moon Mimas was lost in the glare being too close to the planet).

Albireo Double Star in Cygnus April 7, 2012

gallery_double_star_albireo_april7-2012
Albireo is arguably one of the most beautiful double star within reach of a small telescope. It is located halfway between the stars Vega and Altair, along the region of the sky where the Milky Way stretches towards north. The main attraction of this system is the color contrast: the primary is a giant orange spectral type K star, while the secondary is a hot blue spectral type B star. The pair is relatively easy to split even with small telescopes and is best viewed with a little bit of sky glow (e.g., during full moon) to help the eyes appreciate the colors. Image taken with a Sky-Watcher 100 ED 4 in f/9 refractor, Kenko NES mount, Canon 450D DSLR, 15 sec exp, IS0 1600. April 7, 2012, Camarines Norte, Philippines. Photo Credit: Anthony Urbano
