Lecturer: Nikola Antonov
The lecture will focus on the process of collecting and processing astrophotographic material – planets and “deep sky”. Methods of calibration and clearing the various types of “noise” will be covered; how to do auto-guiding or how to “freeze” the sky; what software we shoot with and what settings to choose – exposure, gain, offset. The next phase is to get a final image from the raw material. With examples from practice, we will learn the basic steps in post-processing such as stacking, background extraction/neutralization, photometric color calibration, and histogram stretching, with emphasis on the use of free and open-source software.
Discussion topics: How to impose our personal perspective into the final image of the sky?
