The Omega Nebula Imaged on ATEO-3

Insight Observatory is excited to announce its first deep-sky image set acquired by ATEO-3 that is now available on its Starbase image set repository. M17, the Omega Nebula in the constellation Sagittarius, was the first target imaged from the Insight Observatory affiliate remote telescope. ATEO-3 is a 12.5" f/9 (2860mm focal length) Quasar Optics Ritchey-Chretien owned and operated by Franck Jobard. This telescope is located at an elevation of over 5990 ft at Deep Sky Chile, a remote telescope hosted in the dark skies of the Rio Hurtado Valley in Chile.

The Omega Nebula, also known as the Swan Nebula, Checkmark Nebula, and the Horseshoe Nebula (cataloged as Messier 17 or M17 or NGC 6618), is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier cataloged it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way.

The Omega Nebula is between 5,000 and 6,000 light-years from Earth, and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. The total mass of the Omega Nebula is an estimated 800 solar masses.

M17 is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.

The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars. It is also one of the youngest clusters known, with an age of just 1 million years. The Swan portion of M17, the Omega Nebula in the Sagittarius nebulosity, is said to resemble a barber's pole.

ATEO-3 is available as an option on Insight Observatory's Educational Image Request (EIR) form for educational research and classroom use. This remote online telescope is also an option on the Public Image Request (PIR) as well.

What's In The Sky - October 2019

October nights will be full of celestial treats to see with binoculars and telescopes. Here are some of Orion Telescope and Binoculars' top October stargazing and observing suggestions.

The Sculptor Galaxy, also known as the NGC 253, is an intermediate spiral galaxy in the constellation Sculptor. Imaged on ATEO-1 by Insight Observatory.

The Sculptor Galaxy (NGC 253)

Around midnight local time on October 3rd, the Sculptor galaxy (NGC 253) will be well-positioned for viewing as it will be at the highest point in the sky. Cataloged as both H V.1 and Bennett 4, this 7th magnitude beauty is also known as Caldwell 65, and due to both its brightness and oblique angle is often called the "Silver Dollar Galaxy."

New Moon

For the best conditions to see galaxies, nebulas, and other deep-sky objects, plan a stargazing session for the night of October 27th, when the New Moon will provide dark skies. This is the best night of the month to observe the night sky since light from stars and faint deep sky objects won't have to compete with bright moonlight.

Orionids Meteor Shower

As Orion rises on October 21st around midnight, you can feast your eyes on the peak of the Orionid meteor shower. Around 15 meteors per hour are expected at the peak, but the shower will be active from October 2nd to November 7th.

The Pacman Nebula, also known as the NGC 281, is a bright emission nebula and part of an H II region in the constellation of Cassiopeia. Imaged on ATEO-1 by Insight Observatory.

A Challenging Nebula

Making a small equilateral triangle with the stars Eta and Alpha Cassiopeiae is the elusive Pac Man Nebula, NGC 281. The Pac-Man is a famous target for astrophotographers, but it's not very easy to observe visually. From dark sky locations, you can pick out its faint glow with large binoculars, but a telescope at low power with the help of an Oxygen-III filter will show it best.

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.

Announcing Remote Telescope ATEO-3

Insight Observatory is proud to announce the addition of ATEO-3 to its network of Astronomical Telescopes for Educational Outreach. ATEO-3 is Insight's third affiliate telescope located in the dark skies of the Rio Hurtado Valley in Chile. Rio Hurtado is far away from large cities and offers the darkest skies and the best conditions found in Chile. This location shares the same sky as Cerro Tololo, Gemini South, and the brand-new LSST professional observatories. The ATEO-3 remote imaging system is owned and operated by Franck Jobard and is hosted at Deep Sky Chile. Deep Sky Chile is a remote telescope hosting facility constructed on a flat mountain top over 5590 feet.

Deep Sky Chile remote telescope hosting is located in the Rio Hurtado Valley, Chile where the 12.5" f/9 Quasar Ritchey Chretien (ATEO-3) affiliate remote telescope is housed.

This remote telescope configuration consists of a 12.5" f/9 (2860mm focal length) Quasar Ritchey Chretien with an SBIG STL11000 CCD camera with Luminance, Red, Green, Blue, H-Alpha (6nm) and Oxygen III (3nm) Astrodon filters and is mounted on a Losmandy Titan. An ATEO-3 imaging system is now an option on Insight Observatory's Educational and Public Image Request forms. Multiple hours of deep-sky data integration will also become available in Insight Observatory's Starbase image repository for subscribing. Image data requests can be made on our "Image Sets On-Demand" form to be added to the Starbase imaging queue.

One of the most exciting aspects of receiving image data from this fine instrument is Insight Observatory now has the ability to capture deep-sky gems of the southern hemisphere to offer to educational programs and astronomical image processors. If you have any questions regarding the expansion of our remote telescope network by adding ATEO-3, please feel free to Contact Us. 

We would like to welcome Franck to the Insight Observatory team and thank him for sharing his remote imaging system, helping us fulfill our mission of educational outreach utilizing online remote telescopes.
