Telescopes: The Basics,o telescopes is “How far can you see?” In reality, it isn’t how far the object is away, but how dim it is that concerns the astronomer or astrophotographer. Though the two parameters are somewhat related, a highly luminous object that is far away could appear to be the same brightness as a dimmer ob

Image Capture, you can when you finally get that perfect night. Unless you are entering a photographic Messier Marathon (trying to capture most if not all of the 110 Messier objects in one night), try to avoid this. It’s much better to concentrate on a single, or possibly two objects (after one moves and is no lo

Image Processing,essed image is very much a personal point of view and can depend on what the final image is used for… hanging on the wall, or extracting scientific data from it. These two goals might require different processing techniques. For instance, you don’t want to do any kind of histogram stretch of the dat

Webcam Imaging,gest telescopes tended to make planetary images small on film when the camera was placed at the prime focus of the telescope. To overcome this, a technique known as “eyepiece projection” was used to increase the size of the planet’s image on the film. In eyepiece projection, an eyepiece or other len

Advanced Processing Techniques,plication like astrometry or photometry? Or are we shooting for something to hang on the wall? If the later, then the techniques outlined below apply. For scientific study, we don’t want to do anything to the images that could potentially compromise the data.
