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.

The Andromeda Galaxy Revisited and NGC 6822

Now that the ATEO Portal is complete and in full use for accessing imaging data on ATEO-1, we decided to revisit an old friend... M31, The Andromeda Galaxy. It was just a little over a year ago that we acquired our first image of our closest galactic neighbor. Insight's first image of M31 was a 60-second Luminance image taken remotely with TheSkyX software on the Raspberry Pi that controls the 16" f/3.75 Dream Aerospace Systems astrograph remote telescope. This was before the ATEO Portal was ready for beta testing.

M31 - "The Andromeda Galaxy" Imaged via Insight Observatory's ATEO Portal on it's
16" f/3.7 Remote Robotic Telescope (ATEO-1). 

The latest image above was taken completely through the ATEO online access portal. This image, a bit more impressive, was taken on the morning of October 5th, 2018, with filters Luminance at 600 seconds along with Red, Blue, and Green at 300 seconds. All binning 2x2 and the image processing were done in PixInight and Photoshop CS6.

While the Andromeda Galaxy makes quite an impression, we thought why not image another galaxy of a completely opposite type. NGC 6822 was loaded into the Telescope Console on the ATEO Portal as a target as well. The specifications of this image are Luminance 300 Seconds, RGB 120s, and all 2x2 binning.

NGC 6822 - "Barnard's Galaxy" Imaged via Insight Observatory's ATEO Portal on it's
 16" f/3.7 Remote Robotic Telescope (ATEO-1).

NGC 6822 (also known as Barnard's Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884, with a six-inch refractor telescope. It is one of the closer galaxies to the Milky Way. It is similar in structure and composition to the Small Magellanic Cloud and is about 7,000 light-years in diameter.

Hidden Galaxies

Ever since our new flat field light table was installed on the south wall in Gamma at SkyPi Remote Observatories, the quality of the images coming back from ATEO-1 has greatly improved. Recently the crew at Insight Observatory were imaging random deep-sky objects to test their image processing with the new flats and as they were imaging a few of the most common deep-sky objects for testing, they uncovered a potential project for students that could be a lot of fun while creating colorful deep-sky images...

M97, the "Owl Nebula" imaged by Muir Evenden with a circled unidentified anomaly.

One of the objects randomly imaged was the planetary nebula known as M97, the "Owl Nebula" in the constellation Ursa Major, the Great Bear.  As Insight Observatory's Project Developer, Michael Petrasko, was post-processing the 300-second image originally acquired and processed by Systems Engineer, Muir Evenden, Michael noticed a smudge-like anomaly towards the lower right bottom of the image. The object had very similar characteristics to that of a comet. However, the object was yellowish in color, and comets, for the most part, show up on images as bluish-green in color.

As Michael zoomed into the image to get a closer look at the aberration, he saw many dim disk-like objects randomly scattered throughout. These objects were in fact galaxies.  However,  Michael could still not resolve what that blurry spot of light was in the frame even after being at full zoom. He then circled the object and forwarded it off to Muir for his consultation of what it may be.

Screenshots of the galaxy cluster identified from the Aladin Deep Sky Atlas Software.

Muir was also baffled by the oddity of light so he referenced the SIMBAD image database included in the Aladin Sky Atlas software. With this application, Muir could overlay one of his original luminance frames to determine if the object was in fact in the SIMBAD database of images for comparison. Identification of the blurry object was then confirmed by Muir using the software. The object was a small cluster of galaxies and when viewing an enhanced image of the object from the SIMBAD database, the single blurry object can be resolved as multiple galaxies.

As students acquire images of common deep-sky objects, it would be good practice to task them with zooming in and panning around their images to look for other anomalies such as this one and attempt to identify them with an application such as the Aladin Sky Atlas.
