Bright stars and faint stars: the stellar magnitude system Magnitudes
... Absolute Magnitude: a measure of the intrinsic brilliance of a star • Pick a star (any star) • Imagine moving it to a distance of 10 parsecs • The apparent magnitude it would have is its absolute magnitude • The absolute magnitude is a distanceindependent quantity • Look at Appendix 12 and Appendix ...

... The significance of this rotational period requires understanding Shapley's size of the Milky Way. Shapley had been a supporter of the island universe idea until he determined the Milky Way to be 300,000 light-years in diameter (10x larger than the consensus estimate).

Astrophotography
Astrophotography is a specialized type of photography for recording images of astronomical objects and large areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum light photons over these long periods of time. Photography revolutionized the field of professional astronomical research, with long time exposures recording hundreds of thousands of new stars and nebulae that were invisible to the human eye, leading to specialized and ever larger optical telescopes that were essentially big cameras designed to collect light to be recorded on film. Direct astrophotography had an early role in sky surveys and star classification but over time it has given way to more sophisticated equipment and techniques designed for specific fields of scientific research, with film (and later astronomical CCD cameras) becoming just one of many forms of sensor.Astrophotography is a large sub-discipline in amateur astronomy where it is usually used to record aesthetically pleasing images, rather than for scientific research, with a whole range of equipment and techniques dedicated to the activity.
