In industrialized nations Light Pollution is making it increasinglyĭifficult to find a dark spot. Finding the right spot for taking the image is as important as having the Objects by correlating their position to the position of nearby stars.Īctual image of the same region taken with a Canon EOS 50D and 2 seconds exposure time at ISO 12800.Īstrophotography without a clear and dark sky is impossible. By using this kind of planning it is possible to pinpoint the location of faint The right side contains an actual image of the photo session.Īs you can see the stars match very well. On the left hand side the simulated field of view is shown. The following example illustrates this with a 200 mm objective on a digital Canon EOS capturing the Whirlpool Galaxy. This is especially helpful when imaging faint objects that are hard to find with the bare eye. All you have to do is provide the program with the proper focal length of the camera and the size of the sensor and it will simulate Of an arbitrary objective / sensor combination. This mode allows simulating the field of view For this purpose it features an objective simulation mode. Stellarium will also help you in planning the motive when doing astrophotography. Of the night sky and can be installed on a notebook to support you in finding stars once you are out in the field.Ī screen shot of the software Stellarium showing the constellation Taurus low above the horizon. Stellarium offers an excellent visualization Stellarium is a planetarium simulator that is available for the most commonly used operating systems (Linux, Windows, OS X). A good software for this task is the open source software Stellarium. The observation night should be carefully planned in advance.
