How to image the planets with a telescope and camera

The night sky holds endless wonders, but few experiences match the thrill of photographing planets in vivid detail. With even a modest telescope and camera setup, you can capture cloud bands on Jupiter, the majestic rings of Saturn or the polar caps of Mars — images once the preserve of professional observatories. This technique, known as lucky imaging, records short video clips at high frame rates to freeze fleeting moments of steady air, then stacks the sharpest frames into one crisp photo. No advanced skills are required to start. Whether you own a modest backyard telescope or are shopping for your first planetary camera, this guide provides everything needed to succeed. You will learn a complete workflow that takes you from set-up to finished image, explore why certain planets are easier than others and find answers to practical questions that beginners often ask. Clear skies, patience and practice are your only limits. Soon you will be creating gallery-worthy shots right from home. Planetary imaging relies on video capture rather than single long exposures. Follow these 12 steps for reliable results with most setups. Planning observations in advance is essential! 4. Locate and center the planet either manually or via GoTo. Use the finder scope or red-dot finder, then switch to a low-power eyepiece to bring the target into view and center it as best you can. Jupiter ranks as the top choice for beginners – and perhaps even veterans! Its large disk shows colorful cloud bands, the Great Red Spot and orbiting moons even in modest telescopes. The planet’s brightness and size tolerate average seeing well and reward those even with modest equipment. Saturn follows closely. Its iconic rings and subtle atmospheric banding create dramatic images. While significantly dimmer than Jupiter, modest telescopes easily reveal its brilliant rings, and the belts and zones within the planet’s atmosphere. Mars delivers excitement during its oppositions every couple of years. At closest approach the planet swells in apparent size, revealing dark surface markings, polar ice caps and occasional dust storms. Again, even small telescopes reveal fascinating detail when the planet is close to opposition. Venus offers an easy entry point. Extremely bright and straightforward to locate, it displays clear phases like a miniature moon. Cloud features require ultraviolet filters, but the phases alone impress viewers — even binoculars show these phases clearly. These four planets share key advantages: They appear large and bright enough for small apertures to record good detail on them. Jupiter, Saturn and Mars are the top three – all are fascinating objects to study for observers of all experience levels. Handling the more challenging solar system targets, however, requires more advanced equipment and experience levels. Mercury, Uranus and Neptune present greater challenges. Mercury stays glued to the sun’s glare, visible only briefly at dawn or dusk and best at maximum elongation. Its tiny disk demands exceptional seeing and precise daytime locating skills as well as a decent size telescope. Uranus and Neptune appear as tiny blue-green disks. Their small apparent sizes require at least an 8-inch aperture telescope, longer focal lengths and higher magnification. Larger apertures gather more light, while monochrome cameras with filters help tease out subtle banding. Upgrading to a 10-inch or larger telescope, a high-sensitivity monochrome camera and a filter wheel unlocks these distant worlds. Start with the easier quartet before investing further. When is the best time to image the planets? Aim for nights when the target planet rides high in the sky — ideally near the meridian — to minimize atmospheric turbulence. Planets such as Jupiter, Saturn and Mars look largest and brightest around opposition, when Earth lies directly between them and the sun. But good seeing matters more than the calendar: stable air with low turbulence yields sharper frames regardless of season. Check forecasts and look for periods of high pressure with stable weather and calm winds. Planetary imaging works year-round on clear nights, but spring and fall often deliver steadier conditions. Light pollution is also irrelevant to this form of imaging, so it’s something you can easily undertake from urban locations. What is the most basic setup you need to do this? A 4- to 6-inch aperture telescope on a motorized mount — such as a Celestron NexStar 6SE or anything similar — provides an ideal starter platform. Pair it with an entry-level planetary camera like the ZWO ASI224MC, plus a 2x Barlow lens and a laptop running free software. Total beginner budget often stays under $800 if you already own the telescope. This kit can capture excellent Jupiter and Saturn images without breaking the bank. Skip expensive cooled cameras or large apertures until you gain experience. How long does it take to get a good image? The real key to achieving good image quality is everything you do before pressing the record button: Making sure the telescope is properly cooled down, ensuring it is properly collimated, taking time to focus carefully. All these factors play a huge role. Beyond this, it is largely down to the steadiness of the atmosphere when capturing. The steadier the seeing, the better the result will be! We hope that, with a little practice, this gives you the know-how you need to take stunning images of the planets. If you've yet to purchase the necessary equipment, take a look at our guides to the best telescopes and best dedicated astrophotography cameras.

China's NEV monthly sales share exceeds 60 pct for first time

BEIJING, Aug. 12 (Xinhua) -- China's new-energy vehicle (NEV) sales in July accounted for more than 60 percent of the monthly new car sales for the first time, while the cumulative share for the first seven months also surpassed 50 percent, industry data showed on Wednesday. In July alone, NEV output and sales reached over 1.57 million and 1.56 million units, up 26.8 percent and 23.7 percent year on year, according to data from the China Association of Automobile Manufacturers.

On this day in space! Aug. 7, 1980: NASA's Viking 1 Mars orbiter shuts down 4 years into a 90-day mission

On Aug. 7, 1980, NASA's Viking 1 spacecraft ended its epic and historic mission on the Red Planet. Viking 1 was the first spacecraft to successfully land on Mars. It was one of two Viking missions NASA launched in 1975 to go look for evidence of life on Mars. Each of the Viking missions were composed of an orbiter and a lander. Viking 1's orbiter took photos of the Martian surface that helped NASA decide where to drop the lander. Viking 1: The Historic First Mars Landing in Pictures After four years of orbiting Mars, the orbiter ran out of attitude-control propellant, so NASA had to shut it down. The lander continued its scientific observations for another three years before it lost contact with NASA in 1983. NASA's Viking 1 mission is most well-known for making the first truly successful landing on Mars, but the mission was more than just a huge lander. Viking 1 actually consisted of two spacecraft, the Viking 1 Lander and the Viking 1 Orbiter. The two spacecraft rode to Mars together, with the lander separating from the orbiter ahead of its landing on the Red Planet. In fact, NASA sent FOUR Viking spacecraft to Mars in total. The Viking 2 mission also carried both a Lander and Orbiter. But the Viking 1 probes were the first of that wave. The two orbiters were based on NASA's general Mariner 9 spacecraft bus, but more sophisticated. They carried three primary instrument suites: A two-camera imaging system; infrared spectrometer for water vapor mapping; and an infrared radiometer for thermal mapping. The Viking missions were only planned to last 90 days, but both the lander and orbiter lasted years beyond their design lifetime. The Viking 1 Orbiter studied Mars for four years, orbiting the planet 1,488 times before shutting down on orbit 1,489 on Aug. 7, 1980. The Viking 1 and Viking 2 Orbiters captured a combined 52,663 high-resolution photos of Mars, mapping about 97% of its surface with a resolution of about 984 feet (300 meters). They also snapped photos of Mars' two moons, Phobos and Deimos, in great detail, far surpassing what NASA achieved with the Mariner 9 Mars orbiter in 1971. Want more space history?
