Legacy Software (No longer supported)

MicroObservatory Image 2.3:

• Works on both Macintosh and Windows platforms
• Opens and saves GIF and FITS files
• NOTE for users with Mac OS version 10.8 or later:
  See TECHNICAL NOTES below if you get error when opening downloaded software!

Basic Image Processing:

• Optimize an image's brightness/contrast automatically, by either linear or logarithmic scaling
• Colorize images using several false color tables
• Invert an image's color table
• Increase image contrast and detail using "sharpen" filter
• Reduce the noise in an image
• Manipulate full screen magnification
• Show image information for individual pixels by cursor placement

Advanced Image Processing:

• Perform mathematical operations between two images
• Perform an integer arithmetic operation to an image
• Shift an image relative to another image
• Manipulate an image stack that allows you to create RGB images or animated GIF files
• Crop portions of an image or image stack when an area is selected with the rectangle tool
• Calculate brightness levels and image statistics of an area is selected with the rectangle or circle tool
• Show intensity histograms of the image data
• Display the header of a FITS image
• Place text or graphic lines on an 8-bit GIF file in order to annotate the image

Ease of Use:

• Drag and Drop — you can drag images, files and links onto MicroObservatory Image to open them

Your feedback is appreciated.

Please notify me when a new version of MicroObservatory is released.

Thanks to Wayne Rasband, the author of ImageJ, for color tables and MedianCut code, as well as look-and-feel ideas.
