Dave Eagle, FRAS, astrophotographer, author and astronomy tutor, has been running a number of successful hands-on astronomical imaging workshops and outreach for many years. Following on from this success, he has converted some of the contents of his workshop tutorials into these handy guides.
This 48-page step-by-step guide covers DSLR and Webcam (colour and mono) imaging, showing how to stack DSLR Images, using a long telephoto lens or a telescope, to reduce noise and create a much smoother image. Webcam image processing shows how to add overlapping images to create full-disk mosaics, or take and process detailed surface features, and reveal fainter features along the terminator. The image is then sharpened to reveal more detail before saturating the image to bring out subtle soil colours.
The routines shown use AutoStakkert!, Registax, MS ICE and Photoshop image processing techniques.
