Where Is M13? 2.3

Where is M13? is a new astronomy application that helps you visualize the 3-D locations and physical properties of common deep sky objects. This perspective is rarely discussed in the astronomy books and software products on the market, which focus on apparent data such as right ascension, declination, visual magnitude, and apparent size. Where is M13? aims to address this important lack.

Using paired face-on and edge-on views, the Galaxy View shows you where that cluster or nebula you enjoy viewing in your telescope is actually located relative to the center and plane of the Galaxy, providing a unique three-dimensional perspective of the Galaxy.

The Object List provides important physical information about the objects you choose to list. Galactic latitudes and longitudes as well as luminosities, true sizes, and distances are displayed. A quick click of a checkbox brings up a display of the equivalent apparent data.

The Sky View shows you where the objects displayed in the Galaxy View are located in the night sky, using a star map plotted in galactic coordinates. This use of galactic coordinates, rather than the more common equatorial coordinates, helps you really understand the relationship between what you see in the night sky and an object's galactic location.

We think you'll find that Where is M13? literally adds another dimension to your night sky observing. Enjoy exploring this new perspective!
