The main goal of any astronomical telescope is to gather light. People often focus on the telescope’s magnification, which is actually less important than the instrument’s ability to collect more light than the observer’s unaided eye can. When choosing a telescope, many different characteristics...

With a telescope, observers can see planets, stars, galaxies, nebulae, and even certain astronomical events like meteor showers or solar eclipses. The clarity and range of the observations largely depend on the location, weather, pollution, experience, type of telescope and its specifications. ...
Astrophotographyis a photography niche that captures images of astronomical objects, celestial events, and the night sky. It requires specialized equipment such as telescopes, cameras, andlensesto capture images of celestial objects like stars, planets, and galaxies. Astrophotography requires the photograph...
Cooper (2016) suggests, however, that all locations are relative, even those we consider to be fixed locations on the Earth when we consider them from an astronomical perspective, so we could think of the location in (12) as being the relative location “around you”. One might object also...
