petapixel.com – It’s amazing the kinds of space photos that amateur photographers can create from their own backyards these days. Case in point: the high-resolution moon photo above was captured last week by Polish photographer Bartosz Wojczyński. It was stacked together using 32000 separate photos.
Wojczyński tells us that he used “advanced image acquisition and processing techniques,” mapping violet and infrared images of the moon to blue and red channels in the final shot.
It took him about 28 minutes to shoot 32000 photos weighing 73.5 gigabytes using his ZWO ASI174MM monochrome camera, a couple of filters, his Sky-Watcher HEQ5 mount, and his Celestron C9.25 telescope (which is equivalent to a 2350mm f/10 camera lens) — equipment that cost him about $3500 total.
The photography was done from the balcony of his apartment in Piekary Śląskie, Poland:
After the thousands of images were captured, Wojczyński spent 5-6 hours processing and stacking the images together into the 14 megapixel final image. Click here to see the original image in all its full-res glory. Here are some crops showing the details of the photo:
“Thanks to the enhanced coloration, it’s possible to examine the differences in the chemical composition of the lunar surface,” Wojczyński tells us. “For example, the bluish tint of several areas indicates a titanium-rich soil.”
P.S. Wojczyński is the same photographer that made the six-hour exposure of the celestial north pole that we featured last month.
Skyandtelescope.com – April 22, 2015. Walk in the astronauts’ footsteps as you explore the places they visited in the heyday of Apollo program. Use these helpful maps to start you on your way.
We all love dark moonless skies, but let’s face it, the Moon’s out two weeks a month. How can you ignore it? You’ve doubtless observed craters and mountain ranges and probed for volcanic features like rills and domes. But here and there among the nooks and crannies, you’ll find six of the most remarkable locales on the Moon — the Apollo landing sites. They’re the only places where humanity has achieved one of its oldest dreams and “touched the stars”.
As you’re well aware, no telescope on Earth can see the leftover descent stages of the Apollo Lunar Modules or anything else Apollo-related. Not even the Hubble Space Telescope can discern evidence of the Apollo landings. The laws of optics define its limits.
Following are maps for pinpointing each Apollo location. South is up, and clicking on the images will link you to higher resolution versions. Time to strap on your boots and follow in the footsteps of the first people to walk on the Moon.
Hubble’s 94.5-inch mirror has a resolution of 0.024″ in ultraviolet light, which translates to 141 feet (43 meters) at the Moon’s distance. In visible light, it’s 0.05″, or closer to 300 feet. Given that the largest piece of equipment left on the Moon after each mission was the 17.9-foot-high by 14-foot-wide Lunar Module, you can see the problem.
Did I say problem? No problem for NASA’s Lunar Reconnaissance Orbiter (LRO), which can dip as low as 31 miles (50 km) from the lunar surface, close enough to image each landing site in remarkable detail.
LRO’s orbital imagery and photos taken in situ by the Apollo astronauts will serve to illuminate our ramblings from one Apollo site to the next. All the landing sites lie on the near side of the Moon and were chosen to explore different geologic terrains. Astronauts bagged 842 pounds (382 kg) of Moon rocks, which represented everything from mare basalts to ancient highland rocks to impact-shattered rocks called breccias. Apollo 12 astronauts even found the first meteorite ever discovered on another world, the Bench Crater carbonaceous chondrite. – See more at:
With the Moon waxing this week and next, the advancing line of lunar sunrise will expose one site after another beginning with Apollo 17 in the Moon’s eastern hemisphere and finishing with Apollos 12 and 14 in the western. To see each locale, a 4-inch or larger telescope magnifying 75× or higher will get the job done. But the larger the scope and higher the power, the closer you’ll be able to pinpoint each landing site and better able to visualize the scene.
The base images for all the sites are photographs taken by the LRO. I encourage you to drop by the ACT-REACT QuickMap site, which features a zoomable lunar map of LRO photos that will practically take you down to the lunar surface. Click the “paper stack” icon and uncheck Sunlit Region to see a fully-illuminated Moon, no matter the current phase. Checking the Nomenclature box will bring up the names of craters, rills and many other features. More details about each of the LRO Apollo photos can be found here.
Bandar Seri Begawan (2015 April 04) – Sky gazers and eclipse watchers gathered in the evening at Dermaga Diraja in the capital to observe the full eclipse of the Moon. The event was co-organised by Sultan Sharif´Ali Islamic University (UNISSA), Survey Deparment and the Astronomical Society of Brunei Darussalam.
Despite the weather was partly cloudy, most of the eclipse stages were observable from moon rise, at about 7 pm, till the end of partial phase, at 9.45 pm.
Totality’s duration was less than 5 minutes that made this phenomenon as the briefest sight of totality in the 21st century.

During the Lunar Eclipse, a Sunat Gerhana Prayer was performed at the nearby surau as a recommended prayer (salatul-kusuf) in congregation. Public talks on the Scientific and Islamic perspectives of the eclipse and its significant were also delivered by Haji Julaihi bin Hj Lamat of Survey Department and Dr Sayyed Abdul Hamid al-Mahdaly from UNISSA.
Present during the event were the co-chairperson, Dr Haji Norarfan bin Haji Zainal (UNISSA’s Rektor) and Hj Julaihi bin Haji Lamat (Survey Department).
PABD wishes to thank all working committees of UNISSA and Survey Department for your hard work making this event possible, and non-stop huge responses from members of the public for the continuous support.
RTB NEWS AT 10: Moon Eclipse Observation

People in Brunei Darussalam had the opportunity to watch an astronomical phenomenon – the Eclipse of the Moon. The total eclipse occurred for four minutes between 7:58 to 8:02 last night. The observation was conducted by the Brunei Darussalam Astronomy Association with the cooperation of the Survey Department and the Sultan Sharif Ali Islamic University, UNISSA.
The Royal Wharf in the capital became the observation centre for people to witness the phenomenon. Several telescopes were provided by the organisers to allow members of the public to gaze at the lunar eclipse in good weather. The phenomenon occurs when the Sun, Earth and Moon line up causing the Moon to pass through the Earth’s shadow. The brief spectacle was also seen in Japan, Australia, and New Zealand as well as western North America. A partial lunar eclipse is predicted to occur in August 2017
Bandar Seri Begawan – Look west in twilight on February 20 and 21 as two planets, Venus and Mars, appear close one another in the sky and will be accompanied by the thin moon crescent. The celestial phenomena known as conjunctions occur when celestial bodies have the same right ascension or the same ecliptic longitude as seen from the Earth. While it would be very low in the twilight sky, it might be an interesting photo opportunity. Venus will be shining bright in the west after sunset and sky gazers can locate Mars as they are separated within 1 degree apart. If the weather cooperates, it could be a spectacular image.
