What's In The Sky - June 2019

Get ready for summer stargazing! With the weather warming up, June is a great time of year to enjoy relaxing evenings under starry skies with your telescope or astronomy binoculars. Here are a few of Orion Telescopes and Binoculars top picks for June 2019 stargazing:

Jupiter at Opposition

Jupiter shines brightly in the constellation Ophiuchus during June and will be at opposition to the Sun on June 10. Around the same time is also its closest approach to Earth, making it an ideal time for observation. Use a SkyQuest XT6 PLUS Dobsonian along with the 10mm Plossl eyepiece and Shorty 2x Barlow lens that come with it to get views of the largest planet in our solar system at 240x magnification! Or, pair it with the Orion StarShoot 1.3mp Solar System V Imaging Camera for an affordable planetary imaging system!

Summer is Globular Season!

Globular star clusters are densely packed balls of stars that are concentrated towards the center of the Milky Way. June skies offer some of the finest globular cluster viewing opportunities. While you can detect most globular clusters in 50mm or larger binoculars, a moderate to high-power eyepiece in a 6" or larger telescope offers the best chance to resolve individual stars. In the constellation Hercules, look for M92 and the “Great Cluster” M13. In Scorpius, look for M4 and M80. The constellation Ophiuchus is home to six globulars – M10, M12, M14, M107, M9, and M19. Can you spot them all?

The Virgo Cluster

A treasure trove of galaxies can be explored if you point your 6” or larger telescope toward the Virgo Galaxy Cluster. The Event Horizon radio telescope array released the first image of a black hole in April, of the supermassive black hole in M87. While the black hole might need an Earth-sized radio telescope array to resolve it, the galaxy itself can be viewed with more affordable equipment. Aim your telescope at M87 in the constellation Virgo and start scanning the surrounding night sky. How many galaxies can you see?

Summertime Star Party

Take advantage of the New Moon on June 3rd and the galaxies and globular clusters visible to put on a star party! Not only will the dark skies of the moonless night provide great opportunities to see fainter objects more clearly, but the warm June weather will make it easy to enjoy starry sights all night long with friends and family.

Swirling Spirals

Around 10pm in mid-June, two glorious, face-on spiral galaxies M51 and M101 will both be in a great position for viewing and imaging. Look for M51, the Whirlpool Galaxy, to the southwest of the star Alkaid at the end of the Big Dipper's "handle". Scan the sky to the northeast of Alkaid to find M101, the Pinwheel Galaxy. Under very dark skies, these distant galaxies can barely be detected in smaller telescopes, but a 10" or larger reflector will reveal much more impressive views. If you're viewing from an especially dark location, try to resolve the delicate spiral arms of M51 in a 10" or larger telescope.

Gems of the Summer Triangle By 10pm in mid-northern latitudes, the Summer Triangle, comprising beacon stars Vega (in Lyra), Deneb (in Cygnus), and Altair (in Aquila), will be fully visible above the horizon. Several celestial gems lie within its confines, including the Ring Nebula (M57), the Dumbbell Nebula (M27), open star cluster M29, and the visually challenging Crescent Nebula (NGC 6888). To catch a glimpse of the elusive Crescent, you'll almost certainly need an Orion Oxygen-III Filter in a larger telescope.

Summer Sky Challenge Discovered in 1825 by the German astronomer Friedrich Georg Wilhelm von Struve, NGC 6572 is bright enough to be seen in a humble 60mm refractor telescope from a dark sky site; but it is very, very small! At only 8 arc-seconds in size, it takes a lot of magnification to distinguish this from a star. The easiest way to find it is to look in the target area for a green star. NGC 6572 is one of the most intensely colored objects in the night sky. Some say this is green, some say it is blue; what do you think?

All objects described above can easily be seen with the suggested equipment from a dark sky site, a viewing location some distance away from city lights where light pollution and when bright moonlight does not overpower the stars.

What's in the Sky - May 2018

Get outside with your telescope (or without a telescope) on clear May evenings to see celestial treats recommended by Orion Telescopes and Binoculars! With weather warming up and skies clearing up, there's no shortage of celestial delicacies to view with telescopes and binoculars. Here are a few of Orion's top suggestions for May observing:

Eta Aquarid Meteor Shower

Grab a blanket or a comfy lounge chair to sit back, relax and watch the Eta Aquarids meteor shower, one of two annual showers caused by dust particles from Halley's Comet. Catch the peak of the dazzling show before dawn on May 6. The waning gibbous Moon might outshine some of fainter meteors, but there will still be opportunities see meteors streak across the night sky at the approximate peak rate of about 30 per hour. Look for meteors appearing to radiate from the constellation Aquarius.

Bright Jupiter

Jupiter reaches opposition on May 9th, making it the best night of the year to explore the gas giant planet and its four brightest moons Io, Europa, Ganymede, and Callisto. Since Jupiter will be directly opposite the Sun from Earth, it will be visible all night long. Opposition occurs when a planet reaches its closest approach to Earth in its elliptical orbit. Take advantage of Jupiter's brightest night of the year and take a closer look at its cloud band "stripes" and four Galilean moons with any size telescope.

Four Big Planetary Nebulae

Use a 6" or larger telescope and an Oxygen-III or UltraBlock filter to catch nice views of four relatively large planetary nebulae in May skies. See the "Ghost of Jupiter," NGC 3242 in Hydra; M97, "the Owl Nebula" in the Big Dipper; NGC 4361 in Corvus, and the famous "Ring Nebula", M57 in Lyra just a few degrees from bright star Vega. To help you locate these objects, use the The DeepMap 600.

New Moon, Dark Skies

Take advantage of the dark skies provided by the New Moon on May 15th to scope out the many star clusters, galaxies and other deep-sky gems on display. Pack up your astronomy gear using our full line of telescope and accessory cases and head to a dark sky site for the best viewing conditions.

Five Glittering Globular Clusters

Five picture-perfect examples of globular star clusters will be visible in May skies. Check out M3 in the constellation Bo├Âtes. M13, the "Great Cluster in Hercules" will be visible near the zenith. M5 can be found in Serpens, and M92 in the northern section of Hercules. Be sure to track down M4 (NGC 6121) in Scorpius on May 27th, as it will be in a great position for telescopic study throughout the night, reaching zenith around midnight. Big telescopes will provide the best views, but even a pair of humble 50mm or larger binoculars will show you these dense balls of stars from a dark sky site.

Crescent Moon and Venus

After the sun sets on May 17th, you'll find a stunning view of the waxing crescent moon to the left of brilliant Venus. While you're observing the pair, use at telescope to look for the crater Furnerius at the lower right of the crescent moon's face. Try Orion's 1.25" Orion 25% Transmission Moon Filter, perfect for crescent phases, to improve lunar contrast and tone down glare.

Four Face-On Spirals

Use a large telescope to see the classic pinwheel shapes of galaxies M51 and M101 in the Big Dipper asterism of Ursa Major, and M99 and M100 in the Virgo galaxy cluster. There are also dozens of additional galaxies to explore in the Virgo cluster with a large aperture telescope.

All objects described above can easily be seen with the suggested equipment from a dark sky site, a viewing location some distance away from city lights where light pollution and when bright moonlight does not overpower the stars.
