Where is M13? helps you visualize the locations and physical properties of deep sky objects in and around the Galaxy.
Using paired face-on and edge-on views of the Galaxy, this application shows you where that cluster or nebula is actually located relative to the center and plane of the Galaxy — a three-dimensional perspective.
Where is M13? is useful for both at home and in the field. At home, used together with a star atlas or observing guide, this software helps visualize the 3D nature of the Galaxy. In the field, it can enhance your viewing experience by supplying the missing third dimension to your 2D telescopic or binocular views. Where is M13? is particularly useful during public outreach events for explaining the large scale structure of the Galaxy and showing guests where the objects they view are actually located.
Features include:
- Galaxy View shows you paired face-on and edge-on views of the Galaxy. It uses the new “two armed” rendition of the Galaxy fro Spitzer.
- Sky View displays the night sky as plotted using galactic coordinates. This system helps users to see where deep sky objects and familiar stars are located relative to the plane of the Galaxy.
- Object List lists the deep sky objects in the database that match the filters you have set.
- Presets – allows you to open “preset” documents. Presets are documents placed in one of two specific directories.
- Zooming in and out with very fine controls.
- Filters Menu is used to choose which objects in the database are displayed in the Object Table
- Uses a number of important sources, like the Messier catalog and a few others.
- Cross-platform support – works with Linux, Mac OS X, and Windows operating systems. The software uses Java.
