From the developer:
CCD Explorer allows you to organize you CCD images in a nice neat program. The program allows you to enter data about each CCD image and lets you set filters displaying a subset of the CCD images you have taken.
CCD Explorer does not support FIT or SBIG file format, but it does support almost any other common graphic format such and JPEG, BMP, GIF, or TIFF files. The program does allow some image processing but is mainly a viewer.
