New Galaxy Image Sets from ATEO-3

Insight Observatory's affiliate remote telescope, the 12.5" f/9 Ritchey Chretien (ATEO-3) located at Deep Sky Chile has been very busy as of late producing additional image sets for Starbase. The latest additions to Starbase from ATEO-3 are image sets of Messier 83, the "Southern Pinwheel Galaxy", and NGC 1313, also known as the "Topsy Turvy Galaxy".

Messier 83 - the Southern Pinwheel Galaxy imaged on ATEO-3 and processed by Franck Jobard from Deep Sky Chile, now available for download from Starbase.

Messier 83 or M83, also known as NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation borders of Hydra and Centaurus. Nicolas Louis de Lacaille discovered M83 on February 23, 1752, at the Cape of Good. Charles Messier added it to his catalog of nebulous objects (now known as the Messier Catalogue) in March 1781. It is one of the closest and brightest barred spiral galaxies in the sky and is visible with binoculars. Its nickname the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy (M101) in the northern constellation Ursa Major.

Starbase image set "M83 - Lum (2021): Southern Pinwheel Galaxy" has over 10 hours of Luminance image data and set "M83 - RGB (2021): Southern Pinwheel Galaxy" consists of 3 hours each of Red, Green, and Blue image data. 

Image Set Rates:

• M83 - Lum (2021): Southern Pinwheel Galaxy is only $24.40 USD for Education and $30.50 USD for Standard. 


• M83 - RGB (2021): Southern Pinwheel Galaxy is only $21.60 USD for Education and $27.00 USD for Standard.

NGC 1313 - the Topsy Turvy Galaxy imaged on ATEO-3 by Franck Jobard and processed by Utkarsh Mishra from Deep Sky Chile is now available for download from Starbase.

NGC 1313 is a field galaxy and a barred spiral galaxy discovered by the Scottish astronomer James Dunlop on 27 September 1826. It has a diameter of about 50,000 light-years or about half the size of the Milky Way. NGC 1313 lies within the Virgo Supercluster. NGC 1313 has a strikingly uneven shape and its axis of rotation is not exactly in its center. The galaxy also shows strong starburst activity and associated super-shells. NGC 1313 is dominated by scattered patches of intense star formation, which gives the galaxy a rather ragged appearance. The uneven shape, the ragged appearance, and the strong starburst can all be explained by a galactic collision in the past. However, NGC 1313 seems to be an isolated galaxy and has no direct neighbors. Therefore, it is not clear whether it has swallowed a small companion in its past.

Starbase image set "NGC 1313 - Lum (2021): Topsy Turvy Galaxy" has over 8 hours of Luminance image data and set "NGC 1313 - RGB (2021): Topsy Turvy Galaxy" consists of over 7 hours of Red, Green, and Blue image data.

Image Set Rates:

• NGC1313 - Lum (2021): Topsy Turvy Galaxy is only $20.00 USD Education and $25.00 USD Standard.


• NGC1313 - RGB (2021): Topsy Turvy Galaxy is only $18.40 USD for Education and $23.00 USD Standard.

What's In The Sky - June 2020

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 2020 stargazing and observing:

Solar System Trio

Rising in the southeast on June 7th and 8th, Jupiter, Saturn, and the Moon are well placed for observation, with 5 degrees of separation between Jupiter and Saturn. On the 7th the Moon approaches Jupiter with a separation of 6 degrees, and on the 8th it is 4.5 degrees away from Saturn. They will rise around 11pm, and reach their highest point in the sky around 4am, providing ample observing time. Grab a planetary guide set to identify surface details or a Barlow lens for high-magnification viewing!

M13 - The Great Globular Cluster in Hercules imaged on Insight Observatory's 16" f/3.7 astrograph reflector (ATEO-1). Image data was acquired by Muir Evenden and processed by Utkarsh Mishra.

Summer is the Globular Season!

Globular star clusters are densely packed balls of stars that are concentrated toward 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 the 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?

Summertime Staycation

Take advantage of the New Moon on June 20th and the galaxies and globular clusters visible for a great Staycation at home! 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. The New Moon also brings an annular solar eclipse, but this is only visible from parts of Africa and Asia.

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, and 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.
