Astrophotography Lab (APLab) is a free program intended for anyone interested in astrophotography. It has two main purposes:
APLab supports a wide range of CCD and DSLR cameras and telescopes by default, and you can easily add the necessary information for your own equipment.
- Interpreting data extracted from your astrophotos to produce useful information.
- Using this information as a help for further improving your imaging results.
- Automatically estimate the optimal ISO and exposure time for the object you want to image.
- Automatically calculate gain, read noise, full-well capacity and other sensor characteristics of your camera.
- Calculate the signal-to-noise ratio, skyglow, dynamic range etc. simply by selecting areas of an image.
- Find out how camera settings and imaging conditions will affect your images by plotting graphs or simulating a synthetic image.
- Measure the field of view or angular distances in your image.
- Get useful information about your camera, optics, image and imaging conditions.
- Explore potential imaging targets by viewing their size in the field of view, and obtaining information about their location in the sky.
