... 20.) Lalande 21185 is an M2 red dwarf about 8 LY away and Betelgeuse is an M2 red supergiant about 600 LY away. Both have a temperature of about 3500 K, but we can see Betelgeuse and not Lalande 21185 with the naked eye because… A – Betelgeuse is so much more luminous. B – Betelgeuse has an apparent ...

How To Guide: Astrophotography with a DSLR
... With this method you have a lot more flexibility. You can do this in moderately light polluted environments and when the moon is out as well. The basic idea is instead of taking one single 60 minute exposure you would instead take 60 separate 1 minute exposures and stack them to make it look like a ...

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.
