Astronomical Imaging Course Description and Requirements Organization Projects and Assignments Course Web Site Course Description and Requirements This course is designed as an introduction to the techniques for obtaining, processing, and analyzing astronomical images. Currently, virtually all astronomical data is obtained as an "image" of some kind. Furthermore, the detector of choice in astronomy is currently the CCD, so this course will deal exclusively with digital images obtained with CCD detectors. Since digital images and CCD detectors are now quite common in most of the physical sciences, this course can also serve as a general introduction to scientific image processing and analysis. However, this course could also be used merely as an excuse to obtain and enhance images of those spectacular objects visible in the night time sky. The course will cover the use of observatory mounted telescopes, the use of CCD cameras, and the use of image processing software packages. In broad terms the course will cover the following general topics: Locating and identifying objects in the sky using astronomical telescopes Using and calibrating CCD detectors Image processing and analysis of digital images It is presumed that class participants will have an introductory knowledge of astronomy, will have previously taken a laboratory course in science, and will be familiar with using personal computers. You should be prepared to spend some time with your lab partners at the University Observatory at night in the cold. You should also be prepared to spend time at a computer processing your images.

List by year News And Photo Releases News - heic0412: FITS format liberation – DIY astronomical images with the expert touch 08-Jul-2004: For many years astronomical images from the world’s telescopes were reserved for an elite of astronomers and technical people. Now anyone with a desktop computer running Adobe® Photoshop® software can try their hand at crafting astronomical images as beautiful as those from the Hubble Space Telescope. A free software plug-in, released today, makes a treasure trove of archival astronomical images and spectra from the NASA/ESA Hubble Space Telescope, the European Southern Observatory's Very Large Telescope, the European Space Agency’s XMM-Newton X-ray observatory, NASA’s Spitzer Space Telescope and many other famous telescopes accessible to home astronomy enthusiasts. If there is anything that unites astronomy, it is the worldwide use of a single file format - nearly all the images of stars and galaxies produced by telescopes on the ground and in space are stored as so-called FITS files. Unfortunately this file format has been accessible to very few people other than professional scientists using highly specialised image-processing tools. Now a new and unique tool - the ESA/ESO/NASA Photoshop FITS Liberator – developed by imaging scientists at the European Space Agency, the European Southern Observatory and NASA makes the immense wealth of astronomical images and spectra stored in data archives around the world accessible to the layman. The only thing required is access to either Adobe Photoshop® or Adobe Photoshop Elements®, both leading image software packages.

CADET Welcome to CADET homepage Download Installation Using CADET About image calibration ... Who am I? CADET is basically a program for calibration and deconvolution of astronomical images in FITS, BMP and JPEG formats. See a screenshot CADET is a graphical processor with powerful functions and in continuous evolution. Additionally to calibration and deconvolution , it has a variety of graphic functions such as: I have considered to publish test, beta versions of the program in the web. I have not done this due to several reasons: Thanks to Jordan Russell and his very fine Inno Setup program, CADET installation and uninstallation is now automatic. You can get the DJGPP compiler in ftp.simtel.net server, directory pub/simtelnet/gnu/djgpp or in any of its mirrors. This product includes software developed by the University of California, Berkeley and its contributors. JPEG file handling in CADET software is based in part on the work of the Independent JPEG Group. Free and unrestricted CADET use and distribution is encouraged for non trade purposes. Most of the contents in this web page comes from CADET on line documentation, with some minor modifications.

The possible range of the pixel values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales. Figure 3: A true-colour image assembled from three greyscale images coloured red, green and blue. Such an image may contain up 16 million different colours Figure 4: the additive model of RGB. Red, green, and blue are the primary stimuli for human colour perception and are the primary additive colours. Courtesy of adobe.com. Figure 5: The colours created by the subtractive model of CMYK don't look exactly like the colours created in the additive model of RGB Most importantly, CMYK cannot reproduce the brightness of RGB colours. In addition, the CMYK gamut is much smaller than the RGB gamut. Courtesy of adobe.com. Figure 6: This illustration clearly shows the different gamuts of the RGB and CMYK colour spaces.
