On the surface, imaging the planet Jupiter can seem relatively easy as planets go. It’s big (46″ angular size) and bright (-2.7 magnitude now), in fact Jupiter is the brightest of the planets next to Venus or Mars (during a good opposition). But, imagers are often disappointed with their initial attempts with the great planet.
To help in the quest for high resolution images of Jupiter, I put together a class called “The Challenges of Jupiter Imaging”. Instructor in Astronomy Jim Honeycutt offered a classroom at Emory Univeristy’s Oxford College in Covington, GA, and on August 23, 2008 we presented the class to about 16 amateur astronomers and others interested in the subject.
The class was a lot of fun, and turned out to be educational for everyone, including me. The labs were probably the most interesting and included stacking techniques for Jupiter images using Registax, and some rather detailed color combining and processing tricks in PhotoShopCS.
Thanks to Jim Honeycutt and Oxford College for an excellent place to have the class and for the drinks and snacks everyone enjoyed during break. Thanks also to Jon Wood for video taping the class!
Below you’ll find links to the presentation, some of the images used in the course and a video of the class. If you would like to take the course online, first download the presentation, then download the workshop images and watch the video. You should have Registax v3 or v4 and PhotoShop on your system for the course. The “avi” files used in the class are not included below because of size, so use some of your own during the course, or just watch the Registax lab.

Here’s an outline of the course.
Below are links to the 5 monochrome workshop images that were used for color combining (Don’t forget to convert these to ”grayscale” before attempting to process them):
NOTE – RIGHT click on each link and “Save Target As” (these are .tif format files):
The video (below) is available in both Windows Media (recommended) and Real Media. Your player should start the video in just a few seconds after clicking the link, but if the player wants to download the video completely before showing it, that should only take a few minutes, so be patient.
