Introduction: As information changes, this article will be updated. It is always UNDER CONSTRUCTION. Every now and then an amateur astronomer asks me what equipment they will need to do good CCD imaging, or what the techniques are for good imaging. The questions lead to more questions, more answers, and a lot of typing! Compiled... Continue Reading →
These two phrases are pretty much guaranteed to raise the blood pressure of optical aficionados: Comatic Aberration and Chromatic Aberration. There. Did your blood pressure go up? Then it is likely you have dealt with one or both of these issues before... and it is likely that you do not need to read further! For... Continue Reading →
This is not for the faint of heart. You need to know how to use a CCD imager and your telescope. I write this here, because there are so many websites with INCORRECT information about this process. Some miss the point completely. All this does is mess with your head and mess with your gear.... Continue Reading →
Introduction: When taking CCD images, and particular, when trying to use those images for scientific purposes, it is important to reduce the amount of unwanted signal and unwanted noise from each image. Optical path “noise” (some of which is actually signal), is such a problem that many astronomers really never come to grips with it.... Continue Reading →
