Just to let you all know that
Solar Eclipse Maestro 1.8.3v2 is now available.
There are two versions, one Universal Binary and the other Intel. The UB version does support Canon's legacy cameras (350D, 20D/20Da, 5D) but not the latest models such as the 1D X, while the Intel version doesn't support Canon's legacy cameras but does support all the latest models.
Of course all Nikon cameras are supported by both versions, and all SBIG CCD cameras with their filters wheels as well.
