Op 1 Junie 2009 het ek die eerste keer oor die "Star Gazer’s Deep Space Atlas, Outdoor Viewing" geskryf. Nou is die die nuwe verbeterde weergawe hier. Dit is nou beskikbaar. Bestel dit gerus.
Hoekom die opgewondnheid.
Dit is vir die Suidelike halfrond saamgestel.
Dit is gemaak om buite by jou teleskoop of verkyker gebruik te word
Blaaie is doubestand. Wonderlik vir die vroegoggende buite.
Bladsyagtergrond is swart met wit teks en voorwerpe daarop.
Konstellasies in die naghemel word maklik opgespoor.
So ook die voorwerpe in die naghemel.
Daar is `n “Sky Tour” om jou te help om die boek te gebruik.

All of S&T on DVD
Rumors have been flying around for months, but now it's official. Starting today, we're taking orders for The Complete Sky & Telescope: Seven Decade Collection.
Click above for full information on the DVD collection — and to order your own copy online.
This set of eight DVD-ROMs includes every issue published from November 1941 through December 2009, plus a unified index for the complete set with full text search for every word ever printed.
I don't know if you're excited, but I sure am! For anyone interested in the history of astronomy, the back issues of Sky & Telescope are a goldmine. That's why the 3-by-6-foot bookcase containing bound volumes of all of S&T is the most precious resource in our offices — even more valuable than the thousands of books that have been acquired over the years both by the magazine as a whole and by the individual editors.

Those of us who enjoy spending hours viewing through an eyepiece, have to brave the
elements outdoors, and while summer is the most comfortable, there are the clouds and
seasonal rain that washes out many a good night's observing.
The problem is that best sky viewing is in winter, and while family and friends think you are
crazy, and at times we agree, some of the best objects are visible at this time of year.
Just take the number of objects that are visible in the southern sky in the early evening,
just too many to name that are waiting to fill an eyepiece.
While the Highveld is experiencing the lowest temperatures since 1994, this should not
deter us from taking advantage of moisture-free skies and hunting down those objects
we have not yet seen. So here are some tips to help in viewing at this time.
- Dress in layers, maybe starting with thermal underwear, always a good gift to receive.
I find a top with a hoodie is best, and together with a beanie it keeps the ears even
warmer;
- Wear good boots and warm socks, which are always something we tend to overlook,
until it’s too late and frozen feet soon put an end to viewing;
- Good gloves are important, but check out some hunting gloves that have a flap for
quickly removing your fingers for focusing. Chemical hand warms are cheap and
may help to revive cold hands;
- Stay out of the wind, as a mild breeze can have a wind chill factor of 5 degrees less
than the ambient temperature;
- Take breaks every hour or so and go inside and enjoy a hot mug of your favourite
observing liquid;
- A few short bursts of a hairdryer helps to get rid of dew on lenses, and could also help
to warm other extremities;
- Keep your green laser in your pocket so that it stays warm, as they simply don’t work if
they get too cold.
So if the soccer fans can endure hours in the cold, we can also view our favourite team
of sky objects with a little help from these cold weather tips.
Humans have sent many missions, both manned and robotic, beyond our planet to explore our neighboring celestial bodies. Now and then, these intrepid explorers have glanced home to provide us with sometimes stunning and always thought-provoking images. The following is a compilation of ten of those homeward glances, from the moon and beyond. - Justin Jernigan
New and detailed observations from the NASA/ESA Hubble Space Telescope have provided insights into two recent events on Jupiter: the mysterious flash of light seen on 3 June and the recent disappearance of the planet’s dark Southern Equatorial Belt.
The triumphant Sunday landing of a Japanese space capsule that visited an asteroid and returned to Earth despite near-overwhelming malfunctions now has scientists around the world asking one final question: Did it actually capture a piece of asteroid Itokawa?
"First, the sample container will be inspected, and then the content will be extracted," said Keiji Tachikawa, president of Japan's space agency JAXA, in a Monday statement. "We hope to find the Itokawa's surface material in the capsule, and contribute to understanding the origin and evolution of the solar system."
