Capturing faint detail in deep-sky astronomical images is all about overcoming noise. Noise comes from a variety of sources: Heat (dark current) CCD readout Light pollution/sky background Cosmic rays Pixel defects Optimal images will reduce these noise sources as much...
Webcams Currently, the best planetary images are being taken with webcams. The techniques that these inexpensive cameras allow make the capable of achieving better planetary images than even the most expensive CCD cameras. For details on using these cameras, visit...
Knowing the field of view of a CCD camera on a certain telescope is critical when selecting targets for imaging. It is also a useful way of comparing cameras or combinations of cameras and telescopes. Pixel size factors into the...
