"On the Moon Again!"

On July 20th, 1969, 600 million people on all the continents followed the first step of a man on the Moon, together with their family or friends, around a radio, and sometimes a television set. Fifty years later, "On the Moon Again" was created to share this enthusiasm for the Moon again in a global, universal movement, transcending all borders.

Insight Observatory and Blake Planetarium collaborated on the evening of July, 12th 2019, by participating in the global event "On the Moon Again".

Scientists worldwide gathered behind "On the Moon Again" and invited Insight Observatory to participate in this unifying event. Their support committee promoted the values of sharing and cooperation. "On the Moon Again" was an initiative of French scientists who coordinated this event with the contribution of thousands of volunteers. Once Insight Observatory was invited to join this global event, we immediately approached the Blake Planetarium located in Plymouth, MA to see if they would have an interest in putting on a joint event with Insight Observatory. The planetarium was very responsive, to say the least. Being that this event was for public outreach, the planetarium was kind enough to offer four showings of the planetarium's program "Earth, Moon, Sun", every half-hour free of charge to the public. This collaboration with Insight Observatory was highly publicized and the result was many reserving their spot ahead of time.

While the programs were running in the planetarium theater by Blake Planetarium Program Provider, Steven Davies, I represented Insight Observatory's contribution by providing a small a Celestron 2.4" refractor telescope set up in the front of the school where the planetarium is located. Using this small instrument would make it easy to pick up and run inside with in the event the skies opened up. Although the telescope was small and designed for the novice astronomer, it still provided decent views of the moon. There was also a back-up plan in case we were completely clouded out in Plymouth, MA. John Evelan, the owner of SkyPi Remote Observatory had his Insight Observatory affiliate telescope ATEO-2B, the Celestron 11" f/10 planetary telescope ready to broadcast images of the moon into the planetarium theater. Unfortunately, he was challenged by cloud coverage in western New Mexico and could only provide a few images of the moon.

As folks were arriving and departing the planetarium, I had the waxing gibbous moon in the telescope's eyepiece for all to see. The weather started out unsettled however fortunately cleared out for most of the outdoor part of the event. Nearly all of the attendees that stopped by to look through the telescope had never seen the moon up so close before. The groups of adults and children of all ages were amazed by the detailed view of the craters, mountain ranges, and mare (seas) they could see with such a small backyard telescope. It was most rewarding guiding them where to look through the telescope for Mare Tranquillitatis (the Sea of Tranquility), the landing spot of Apollo 11.

Blake Planetarium has many public programs throughout the year. You can see what programs they have to offer by visiting bit.ly/BLAKEPLANET.

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 at 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 back yard with a VSD Vixen 380mm & AG14 1330mm Newtonian astrograph. The filter wheel 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. Filters used by Carmelo was a Baader LRGB set.

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

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.

A Perspective of M57 - The Ring Nebula

Recently one of Insight Observatory's generous Patreon supporters, Luis V., requested a dataset of M57, The Ring Nebula, from the 16" f/3.7 Dream astrograph reflector (ATEO-1). After processing the data myself in CCDStack for him, I realized how good the data of M57 really was. Unfortunately, my processing skills don't come close to what most astrophotographers are capable of doing with good image data. Therefore, I shared out the dataset of M57 with Utkarsh Mishra, one of Insight Observatory's Starbase dataset subscribers who is also an accomplished image processor.

What surprised us both was that with such a small amount of data, Utkarsh was able to pull out so much detail of the planetary nebula as well as the background. Utkarsh processed close to only 4 hrs of data acquired from the 16" f/3.7 reflector remote online telescope. 1 hour of Luminance, 50 minutes of Red, 40 minutes of Green, and 45 minutes of Blue (all binning 1x1). He also added H-Alpha data from the 2 meter Liverpool telescope at 120 seconds with a 35% blend of RGB from the telescope. The H-Alpha data exposed the outer part of the Ring Nebula much more than the LRGB data from ATEO-1 could do alone. The 15th magnitude spiral galaxy IC 1296 is also visible just to the upper right of the nebula in the cropped frame above. The software applications used by Utkarsh for processing were Pixinsight, Photoshop CSS and DeepSkyStacker.
