Messier 78 Reflection Nebula

In this post, Insight Observatory features deep-sky object Messier 78. This target was requested to be added to Insight Observatory's image set repository, Starbase by one of its loyal Starbase subscribers.

The image set data was acquired on the 16" f/3.75 Dream Aerospace Systems astrograph reflector (ATEO-1) remote telescope located in New Mexico. There are nearly 10 hours of Luminance, Red, Blue, Green, and Ha image data of Messier 78 available for download on Starbase.

Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. The nebula was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.

M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067, and NGC 2071. This group belongs to the Orion B molecular cloud complex and is about 1,350 light-years distant from Earth. Messier 78 is easily found in small telescopes as a hazy patch and involves two stars of 10th and 11th magnitude. These two B-type stars, HD 38563 A and HD 38563 B, are responsible for making the cloud of dust in M78 visible by reflecting their light.

Insight Observatory is currently taking deep-sky image requests for Starbase image sets on its new ATEO Portal dashboard. There is no charge for these requests. If the requests are approved by the Insight Observatory staff, they will be imaged and uploaded to Starbase for anyone to subscribe to for the low rate of $0.05 (cents) USD per imaging minute for standard subscribers and $0.04 (cents) USD for educational subscribers. We only ask that Starbase subscription requests are for at least 5 hours of integration time.

Complimentary Witch Head Nebula Image Data

In appreciation for all of the recent support, Insight Observatory has received from its users and patrons, nearly 5 hours of LRGB complimentary image data of NGC 1909 (IC 2118) - The Witch Head Nebula has been added free of charge to Starbase, Insight Observatory's image set repository. This image data was acquired on the 16" f/3.75 Dream Aerospace Systems astrograph reflector (ATEO-1) remote telescope hosted at SkyPi Remote Observatory located in the dark skies of New Mexico.

NGC 1909 (IC 2118) - The Witch Head Nebula imaged on Insight Observatory's 16" f/3.7 Dream Aerospace Systems astrograph reflector and processed by Utkarsh Mishra. Complimentary image set available on Insight Observatory's image set repository, Starbase.

Some facts about NGC 1909:

NGC 1909 (IC 2118 - also known as Witch Head Nebula due to its shape) is an extremely faint reflection nebula believed to be a supernova remnant or a gas cloud illuminated by the nearby supergiant star Rigel in the constellation of Orion. It lies in the Orion constellation, about 900 light-years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color.

Radio observations show substantial carbon monoxide emission throughout parts of NGC 1909, an indicator of the presence of molecular clouds and star formation in the nebula. In fact, candidates for pre-main-sequence stars and some classic T-Tauri stars have been found deep within the nebula.

The molecular clouds of NGC 1909 are probably placed closely together to the outer boundaries of the vast Orion-Eridanus bubble, a giant supershell of molecular hydrogen blown by the high-mass stars of the Orion OB1 association. As the supershell expands into the interstellar medium, favorable circumstances for star formation occur. NGC 1909 is located in one such area. The windblown appearance and cometary shape of the bright reflection nebula are highly suggestive of a strong association with the high-mass luminous stars of Orion OB1. The fact that the heads of the cometary clouds of NGC 1909 point northeast towards the association is strong support of that relationship.

Mosaic of Reflection Nebula NGC 6914

Recently we wrote a post covering a collaborative on a mosaic of NGC 7023, The Iris Nebula, imaged by accomplished astrophotographers, Paul C. Swift and Carmelo Falco. This is an image that Insight Observatory was fortunate to be able to contribute to by providing luminance data from the 16" f/3.7 astrograph reflector (ATEO-1). Paul and Carmelo have since produced another astonishing mosaic image, NGC 6914. This deep-sky object is a reflection nebula located approximately 6,000 light-years away in the constellation Cygnus and the plane of our Milky Way Galaxy. The nebula was discovered by Édouard Stephan on August 29, 1881.

This mosaic of the reflection nebula NGC 6914 is made up of data from different focal lengths. 380mm, 1330, 1525mm, and 3400mm. Image processed by Paul C. Swift.

The final image data was processed by Paul C. Swift with data acquired from his backyard with a VSD Vixen 380mm & AG14 1330mm Newtonian astrograph. The filter wheel is an SX-46 with an SX Maxi wheel from Starlight Xpress Ltd. A formatted array of 27 x 21.6 mm and 6uM square pixels. Newtonian telescope at 1330mm and Chroma Filters RGBL mounted on a Paramount MX.

Data for the central area of the nebula was imaged by Camelo Falco using his Ritchey-Chretien C 410mm f7.8 customized at 3400mm and an Apogee Aspin GG16m imaging camera. The mount is a customized RM500 Mount. Carmelo's guiding system is an Orion SteadyStar + Lodestar. The filter used by Carmelo was a Baader LRGB set.

Finally, additional Luminance data for outer areas was taken from Insight Observatory's 16" f/3.7 Astrograph reflector 1525mm (ATEO-1).

The Three imaging systems were used to collect data on NGC 6914, a reflection nebula in Cygnus. Carmelo Falco's 16" f/7.8 Ritchey-Chretien (left), Paul Swift's VSD Vixen 380mm & AG14 1330mm Newtonian astrograph (above right), and Insight Observatory's 16" f/3.7 Dream astrograph reflector, ATEO-1, (lower right).

From the image of NGC 6914 processed by Paul, obscuring interstellar dust clouds appear in silhouette while reddish hydrogen emission nebulae, along with the dusty blue reflection nebulae, fill the cosmic canvas. Ultraviolet radiation from the massive, hot, young stars of the extensive Cygnus OB2 association ionizes the region's atomic hydrogen gas, producing the characteristic red glow as protons and electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight strongly reflected by the dust clouds. The nearly 1-degree wide telescopic field of view spans about 100 light-years at the estimated distance of NGC 6914.
