Ellis Astronomical Observatory

The Sterling Hill Astronomy Group holds occasional viewing sessions at the Ellis Astronomical Observatory on the grounds of the Sterling Hill Mining Museum. 

Located in rural Sussex County, the observatory offers excellent dark-sky viewing conditions far from major urban sources of light pollution.  Members use the observatory's massive 20-inch and 12.5-inch reflector telescopes for nighttime viewing, and a Hydrogen-Alpha telescope for safe viewing of the Sun.


In order to go into the observatory, one must be a part of the occasional viewing session. The next scheduled event at the observatory is the viewing of the transit of Mercury on the morning of November 11th, 2019. The silhouette of Mercury can be seen against the face of the sun through our solar telescopes. There are approximately 13 transits of Mercury each century and the next one after this occurs on November 3rd 2032.
