Astro IIDC" is an astronomy, microscopy, high speed imaging, machine vision and scientifically oriented OS X application developed from the ground up to make FireWire camera imaging easier on the Mac. Simple and easy to use interface in a single camera control window as shown in the screen snap shot to the right. All camera control adjustments are done with a full size scrollable live preview image so there is none of this modal QuickTime tiny 160×120 pixel image approximations nonsense, pure WYSIWYG. For high end FireWire cameras provides CCD exposure times from 1/10000 of a second to 60 minutes (depending on the camera), Region Of Interest and records movies as fast as 240 frames per second. Supports Altivec / SSE3 enhanced Flat Frame division and Dark Frame subtraction to provide for real time removal of optical imperfections (i.e. dust, hairs, vignetting etc.) and to reduce CCD noise.
