![]() ![]() I followed the directions in Using ’s JS9 FITS Editor To Create RGB Images to create this image. ![]() It took about 5 minutes to produce this result, so I’m getting a reasonable result in a short span of time. There’s some detail in the nebula and the overall color is pretty good (the background could be darker). I loosely followed the directions in Processing An Image Using MaxIM DL and Photoshop to create this image. The nebula is a little over-exposed but I suppose that could be adjusted with some work, It took me about 25 minutes to create this image. This image has very little noise and the colors of the nebula are easily visible. ![]() I processed the same FITS files using JS9, FITS Liberator, I took an observation of NGC 2440 and exposed 200 secondsĮach of LRGB and processed the images to produce a set of results for Quality of the observation, and the quality of the image itself. The answer is, it depends on the image: the subject, the SAOImage DS9? What about MaxIM DL? How do I know which application is best to Is best? Does JS9 do better with some images as compared to FITS Liberator or The questions I’m often asked are, which processing application Mandel, Astronomical Data Analysis Software and Systems VIII ASP Conference Series, Vol.I have written extensively about using image processingĪpplications like JS9, Fits Liberator, SAOImage DS9, and MaxIM DL.

The Story of SAOImage DS9: How DS9 got its name Its second generation image display was named TNG and the third is DS9. The High Energy Astrophysics Division of SAO has a preoccupation with things Star Trek. (LGPL) Misc editĭS9 also stands for Deep Space 9.

TkMPEG 1.0: TEA compatible, MPEG 1 encoder. TkBLT 3.0: derived version of BLT, for Tcl/Tk 8.6, TEA compatible, full support for MacOSX and Windows. Other Goodies provided with SAOImage DS9 edit You will need some FITS images to use DS9.ĭS9 can be used as a graphical frontend for other image analysis/processing software: Note the commitment to Tcl/Tk and to open software development.Īlso note the size of the datasets - typically hundreds of Mb for a single observation, but 19Gb for "megasec" exposures from the Chandra X-ray satellite Usage edit The Development of SAOImage DS9, William Joye, Eric Mandel,, gives an interesting outline of the problems of developing and maintaining scientific software It is written entirely in Tcl/Tk (with several binary and script extensions). It is actively developed at the Smithsonian Astrophysical Observatory and is released under an open-source licence (GPL v3). SAOImage DS9 is a data visualization, analysis and imaging application used by professional astronomers. Attributes edit current version 7.5 release time license Download edit SAOImage DS9 main download site saods9 Debian package Description edit It provides for easy communication with external analysis tasks and is highly configurable and extensible via XPA and SAMP. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. SAOImage DS9, a Tcl/ Tk program that uses the SAOTk widget set, is an astronomical imaging and data visualization application. ![]()
