Imaging the night sky has become a popular pursuit for outdoor enthusiasts and those interested in astronomy and space exploration in general. The advances in modern digital cameras and the availability of affordable, high-quality lenses and telescopes has opened the door widely to what was once a specialized and limited activity. The imaging of night-time landscapes with phenomenon such as auroras, meteor showers, and eclipses has also become very popular in recent years.

However, whether digital or emulsion-based, celestial images almost always require specialized processing to bring out the fine details. Many of the subjects are faint and ethereal, and can be easily subdued or lost in the background “noise” of the night sky due to natural phenomenon such as airglow and haze. Man-made noise sources such as light pollution and smog can also be serious impediments. This workshop concentrates on the image processing techniques that can lift the subject above this background noise.

While the workshop includes a limited discussion of equipment setups, it focuses primarily on the post-capture processing of the images. Samples will be provided and a workflow from start to finish is demonstrated, with students working the process as it is shown. While the course content is centered on images captured using a DSLR, it is also applicable to images obtained with dedicated astronomical CCD cameras, film & video cameras, and even point-and-shoot.



 A laptop computer with an appropriate image editing application.  Students should be proficient with their computer and should have a working knowledge of their editing application. While the workshop will be conducted using Adobe Photoshop, suitable alternative applications can also be used, such as:  Adobe Photoshop Elements, Corel Paintshop Pro, or the freeware application GIMP.
