Publisher description for AstroAlign
AstroAlign is a software program for unconventional image processing of astronomical and other images. The program is free and may be used by anyone who finds it useful. However, read the disclaimer at the bottom of this PaGE before you start using it. The current version of AstroAlign accepts 24bit Windows BMP files only. The files may be of any size, but no features are provided for scrolling when the image is larger than the screen. The program is mainly intended for use with images produced by webcams and is therefore optimised for image sizes such as 320x240, 640x480 or Similar. However, I have successfully used the program with larger files. Align the colors by selecting an area in the image, using the mouse. MOVE the mouse to somewhere in the image, press and HOLD down the left mouse button while moving to another location in the image. The selected area is highligthed using inverted colors. When you are done, release the mouse button and the program will calculate the RGB offsets. Notice that which area you select, will determine the color alignment suggested by the program. Below, the three components of a single Star have been isolated in the selection area. The whole image will be aligned independent of the size of the selected area. The program calculates the required x and y offsets for the R, G and B channels, trying to make them overlap. You can edit the values if you want, before pressing the "Align Colors" button.
