- Ideal Exposure Calculator This calculator allows you to determine the ideal exposure time for subframes that will be stacked. It requires that you take a test exposure using your CCD imaging setup and measure the background sky value. Please refer to the CCD Imaging Theory page on Optimum Exposures for the details behind these calculations.
