It’s summer time, and the Milky Way is beckoning. Here are a few tips to help get you started photographing our galaxy.
Meet Regulus A, dubbed "Little King" and "Heart of the Lion," among the 25 brightest stars in the sky. The star belongs to a complex system, including a close white dwarf companion that makes its ultimate fate uncertain.
Does increasing the ISO on your DSLR make it more sensitive? No! Yes! Depends! Find out how ISO affects your astrophotography.
July's a busy month for skywatching. Not only are five bright planets in view, but three comets and a newly-discovered nova are also observable. And it all starts with a bang on Independence Day.
Quality monochrome (black-and-white) images are a much easier route to early success in astrophotography — find out how to get started.
Learn how to edit and process your own nightscape astrophotos using the latest and most popular software.
Betelgeuse, the brilliant red star at the right shoulder of Orion, is a supergiant whose girth extends out to the orbit of Jupiter.
The secret to stacking images in astrophotography is increasing signal rather than just increasing the number of exposures.
Time travel is one of the best things about astronomy. Check out two websites that give skywatchers a more visceral sense of stellar distances and how constellations change shape across the sweep of time.
The just-launched Transiting Exoplanet Survey Satellite (TESS) could soon provide the breakthrough identification of dozens of potentially habitable exoplanets right in our cosmic backyard
Meet the brightest stars near Earth. Next up: Polaris, the North Star, the star within a degree of the north celestial pole.
You don't need a PhD to understand noise in astronomical images — here's an introduction to the various sources of noise in astrophotography and how to combat them.
Meet the stars near Earth, starting with the brightest: Sirius, the "Dog Star."
Is it possible to settle the PixInsight vs. Photoshop debate once and for all? Yes: Learn both and gain the skills you need to make better astrophotos!
A newfound star in a nearby galaxy appears to have cheated death by blowing up at least twice as a supernova. It could be a throwback to the first stars that ever formed.
Want to learn how to take stunning photos of dazzling Aurora? Join Sky & Telescope's live webinar on Monday, March 5th, with National Geographic photographer and founder of The World at Night (TWAN) program Babak Tafreshi as he reveals his techniques for capturing stunning images and time-lapse videos of both northern and southern lights. As…
Capturing crystal-clear astro images involves a delicate balance of having just enough pixels for the object you're imaging. But you don't need a PhD to understand the sampling theory that's involved.
Join Sky & Telescope's live webinar on Monday, January 29th, to find out which 2018 events present the best nightscape opportunities with world-renowned photographer Babak Tafreshi.
A slow, relentless rhythm, known as the saros cycle, is hidden away in the movements of the Moon and Sun. How does it foretell eclipses — and how could Babylonians discover its existence long before modern science and technology?
Knowing your astrophotography setup's pixel scale will help you take better pictures. And to determine pixel scale, you first need to know your field of view.
"As sure as the Sun rises in the east . . ." Except it doesn't! Find out how Earth's tilt changes the location of sunrise (and sunset) throughout the year.
The moment the Sun reaches its southernmost point in the sky marks the December solstice, the official beginning of winter in the Northern Hemisphere (where it is called the winter solstice) and a time of great celebration in many northern cultures.
Good weather for imaging is about more than just the clouds! Even if it's cloud-free, you'll need to understand if the seeing and transparency are good.
