Everything you wanted to know about DSO imaging

Imaging DSO (Deep Sky Objects) involves more than just pointing a camera and clicking the shutter. Al will give the beginner an idea of what governs the length of an exposure, why we stack a series of exposure, and what governs the optimum image. All this is important for selecting your gear: telescope and camera. We will cover the first section at least of the following topics: What makes a good image? Choosing your gear. What to do under the stars. Pre-processing -why and how. Stacking. Stretching. Fixing issues. Al will direct you to resources to answer your questions and / or cover the other topics if desired in later presentations.
