AstroImager is a powerful, but easy to use image capture application for the astrophotography. It has built-in drivers for ATIK and StarlightXpress devices, but it can be used as a client to any remote or local INDI server with any supported CCD or filter wheel as well.
It also controls the set point cooling and the mechanical shutter of the attached camera (if available). It can preview or capture and save images to selected folder with any file name prefix, count, duration and time lapse, browse captured images and show them in Finder, zoom and stretch them automatically or manually. It can measure FWHM and the drift of a selected star to help easier and faster focus and align your equatorial telescope mount.
As far as we know this is the only astro imaging application with ATIK, SX and INDI support in AppStore. It ideally fits to other applications from xINDI project available from our web page.
