Jupiter’s Rotation

Jupiter_July7,2012
An animation of Jupiter demonstrating the planet’s rotation in a span of just 30 minutes, created from a total of 17,000 frames (equivalent to 40 gigabytes of image data), processed using IRIS. Jupiter completes 1 full rotation on its axis every 10 hours. Image captured through eyepiece projection method with a 4-in f/9 refractor, a 25 mm eyepiece, and a Philips SPC900NC/00 web camera.

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.

Saturn March 8, 2012

First attempt in an imaging technique called eyepiece projection. It seems this setup produces better images than using two 2x barlows stacked together to produce the same image scale. Photo Credit: Anthony Urbano. For more images of Saturn, click here.
