IMerge is a program which allows multiple images to be placed.
Edit By BS Editor: IMerge is a program which allows multiple images to be placed onto a large virtual canvas, and arranged to produce a single large composite image, or mosaic. In regions where multiple images overlap, the result is an average of all contributing images - this has the effect of improving the signal/noise ratio. It is possible to feather the edges of images to avoid visible boundaries, and it is also possible to adjust the brightness of each image in order to produce the best match with other images. Once a mosaic has been arranged, iMerge allows the overall brightness levels to be adjusted using a flexible histogram remapping tool.

The images can come from BMP or AVI files (colour or monochrome), or FIT files (monochrome only). Output can be saved in BMP or FIT format.
