	CCD Imaging Equipment
		As the CCD chip should not be placed more than 57mm from the focal reducer it is not possible to use a flip mirror between the reducer and the CCD camera.
		The telenegative increases the focal length of the telescope which is extremely useful for imaging planets where a long focal length is required to increase the size of the planet on the CCD chip and spread the light out so that minimum duration exposures are not saturated.
		This implies the further the CCD chip is from the telenegative the greater the increase in focal length.

	CCD imaging paper
		Despite this attenuation, the signal-to-noise ratio of the CCD data, as determined from reflections of negatively stained catalase crystals, was found to decrease to ~ 50% of that of photographic film data.
		As part of this approach, the slow-scan CCD camera is useful to provide an on-line evaluation of the quality of a crystal in terms of crystallinity, flatness and thickness before the tilt data is recorded (Brink and Chiu, 1994).
		To compare the CCD performance versus photographic film, we used a 'decay plot' in which the logarithm of reflection amplitudes was plotted against the square of the spatial frequency.

	Meade Instruments Corporation - Pictor Series CCD Autoguider/Imagers
		Or imaging a supernova in an obscure 18th-magnitude galaxy.
		CCD sensors are made of semiconducting materials such as silicon that have been manufactured to be sensitive to the impact of light hitting their surfaces.
		Use of the CCD Autoguider has several advantages over the manual method; in general it is much more precise and error-free than is possible with manual guiding, and, in the case of the Meade Pictor 201XT, the autoguider can guide on guidestars as faint as 12th-magnitude, far fainter than is possible during manual guiding.

	About CCD Technology
		With the introduction of Models ST-7 and ST-8 CCD Imaging Cameras, which incorporate two separate CCD detectors, SBIG was able to accomplish the goal of introducing a truly self-guided CCD imaging camera.
		They are mounted in close proximity, both focused at the same plane, allowing the imaging CCD to integrate while the PC uses the guiding CCD to correct the telescope.
		Using a separate CCD for guiding allows 100% of the primary CCD's active area to be used to collect the image.

		This is a measure of the CCD chip's sensitivity to the various wavelengths of light in the spectrum.
		For those wishing to use monochrome CCD's to take color images there are a variety of filter wheels and sliders available that allow one to image through clear, red, green, and blue filters for later combination into a color image (tricolor).
		Other CCD makers are using various techniques to allow the imaging chip to guide the telescope while imaging at the same time.

		In the CCD world, people talk about "quantum efficiency:" if every single photon that falls on the chip is detected, then the chip has 100% efficiency.

	Tri-Color CCD Imaging (Site not responding. Last check: 2007-10-26)
		In both instances, an IR rejection filter is needed for the tri-color work due to the fact that these filters are nearly completely transparent in the IR as well as the fact that CCDs have a very high sensitivity to light beyond 700nm where they eye and film are insensitive.
		A tri-color shot of a color test chart taken with the KODAK filter set and no minus-IR filter will show the chart as just an array of grey swatches but redoing the same shot with the minus-IR filter will show the chart as the eye would see it if the exposures were properly calibrated.
		The process of calibrating using a stellar target is identical to that of using a test target (although one will probably need to use a longer FL and defocus the stellar image in order to get lengthy exposures).

		The term CCD "Charge Coupled Device" is technobabble for the type of semiconductor used in the silicon chip that replaced vacuum tubes in video cameras.
		There are severe limits to what can be done with a $900 autoguider as compared to a full-blown CCD imaging camera, costing thousands but I have found a few classes of objects that lend themselves to what it can do well.
		It was too late to do any serious imaging so I just pointed the scope at the Ring Nebula (M57) to see what my new CCD camera could do and I "discovered" a faint smudge just to the North of it in the same field.

	The art of CCD imaging (Site not responding. Last check: 2007-10-26)
		If the object you were imaging was a continuum source then it wouldn't, but the subject is typically an emission line object and the colours are defined by only a few lines - the strongest of which are Hydrogen alpha (at 656nm), forbidden Oxygen III (at 501nm) and Hydrogen beta (at 486nm).
		I had the telescope and CCD camera in pieces that day doing some maintenance and they were not back together and aligned until too late to take twilight flats.
		I have a dedicated computer for imaging and I keep its clock set to UT, but it drifts and despite having a piece of software that tries to compensate and correct the system clock, for accurate astrometry the time needs to be precise to the second.
