Automatic image registration for astrophotography
RegiStar is a toolkit for deep-sky imagers. It allows several images, possibly taken with different telescopes and cameras, to be processed into a final composite image. Operations require only minimal user input. Common file types, including raw images from cameras with a Bayer grid, are supported.
RegiStar’s unique strength is completely automated yet fully versatile image alignment, or registration. RegiStar finds the stars in an image and uses their positions to align the image to another image or group of images. A sophisticated matching algorithm allows images at different scales and orientations and with only a small overlap to be registered to subpixel accuracy, with geometric distortion corrected. RegiStar requires no user input other than the specification of the images to be registered.
Here is what RegiStar users are saying:
- "Every time I use RegiStar I can't believe how the software knows how to do what it does... that's got to be some of the most amazing code ever written..." Tony Hallas, Foresthill CA
- "I owe much of what I've done to RegiStar...which has essentially revolutionized amateur astroimaging. It certainly has provided the tools for creative imaging which I like to do." Robert Gendler, Avon CT
- "RegiStar is simply one of those 'magic' software programs." Philip Perkins, U.K.

In addition, RegiStar performs dark-frame subtraction and flat-field correction, and also calibrates and assembles images after they have been registered. It can completely handle common astrophotography workflows such as forming mosaics, forming tricolor images, and stacking exposures. RegiStar is also designed so that other image-processing software can be used in conjunction with it.
