Matching Your Camera to Your Optics

by Douglas George In order to get the best results from your equipment, it is important to match the resolution of your camera to the resolution of your optics. In conventional photography your lenses are highly adaptable, with adjustable f/ratio and often zoom capability (adjustable focal length).  On dedicated science instruments such as telescopes and microscopes...

Part I: Fast without the furious: Why your SBIG CCD camera doesn’t have USB 4.0

Part I: Fast without the furious: Why your SBIG CCD camera doesn’t have USB 4.0

There are lots of marketing claims about fast camera download speeds and ever-faster interfaces. It makes you wonder why your SBIG CCD camera doesn’t require a super-fast interface that races along the data highway into your computer. Why is this? It’s really two simple reasons:   Cable Length Sensor Readout Rate In Part I of this blog, we’ll explore...

CCD Imaging 101

CCD Imaging 101

Raw CCD images are exceptional but not perfect.  Due to the digital nature of the data many of the imperfections can be compensated for or calibrated out of the final image through digital image processing.  This page contains some basic definitions used in CCD imaging that you will encounter from time to time: Composition of...
