Finding Targets

Finding Targets
The eVscope is a powerful tool to view and image faint celestial objects of all types. A good starting point are the objects in the eVscope App Catalog, but there are tens of thousands of interesting and worthwhile objects not contained in the Catalog. In addition, there are transient objects and phenomenon that are fascinating and often targets of interest for Science Observations.

Aside from terrestrial and solar observations, finding eVscope targets begin with Orientation. The eVscope/App system has no internal hardware to provide precise telescope pointing information. Only after Orientation can the eVscope be automatically pointed to specific sky locations, and then track those locations as the Earth rotates. (Orientation is also required to use the App to point the telescope to a specific relative azimuth and elevation.) Celestial objects are located using their Right Ascension (RA) and Declination (Dec), a celestial coordinate system that is comparable to geolocation using Latitude and Longitude.

The eVscope's ability to use Enhanced Vision to allow viewing of incredibly faint deep-sky objects (DSO) makes these of particular interest. DSOs are a broad category of telescopic night-sky targets other than individual stars and Solar System objects. These include galaxies, star clusters, and nebulae. There are many lists and sources providing descriptions of DSOs and their location in the sky using their RA/Dec. These include:
