Blink Comparator for iOS – An Image Useful Tool for Amateur Astronomers

icon175x175Independent developer, Roberto De Lorenzo announces Blink Comparator 1.0 for iPhone and iPad devices. Dedicated to amateur astronomers, Blink Comparator alternates the vision of two shots obtained at different times, allowing users to detect changes, highlighted by the blinking of any object (star, asteroid, comet, etc.) visible in one of the images only, or that changed position between a shot and the other. Just mark the same three stars on each picture and press a button.

Ostuni, Italy – Independent developer, Roberto De Lorenzo is proud to announce the release of Blink Comparator 1.0 for the iPhone and iPad. The app allows Amateur Astronomers to compare two images of the same area taken at different times, to see if there are changes, highlighted by the blinking of any object (star, asteroid, etc.) that only appears in one of the images or that changed position or brightness between a shot and the other.

screen322x572After shooting pictures of stars clusters, nebulae, galaxies and so on, often Astronomers check if there are changes compared to the “normal” appearance of the photographed area. To do so, they have to search for a picture (or map) of the same area and check brightness and location of each object. Unless they have a Blink Comparator, that alternating the vision of two shots obtained at different times, allows  to detect and highlight changes or transient phenomena (comets, variable stars, novae and supernovae, asteroids etc.). In the comparator, the sample image and the reference are shown alternately after being aligned with each other. If an object is present in only one of the pictures, it blinks and can be easily found and marked. If an object has changed position between two consecutive shots, during the animation it bounces back and forth, showing the path traveled.
