This colorful shot covers a field of view about the size of the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernovae enrich the interstellar material with heavy elements to be incorporated in future generations of stars.

Purgathofer-Weinberger 1, PuWe1 ( PN G 158.9 + 17.8 ) is a large, circular planetary nebula in the constellation of Lynx.
PuWe1 was discovered by Alois Purgathofer and Ronald Weinberger in 1980 on the Palomar Deep Sky Survey prints. The nebula is one of the largest planetary nebulae visible in our skies, with a diameter of 20 arc minutes. PuWe1 is also one of the nearest known planetaries with a distance of only about 1200 light years.

Image Description and Details :

Next to the tulip nebula is black hole Cygnus X-1. This is the first X-ray source discovered in Cygnus and the first black hole ever confirmed. The blue star HD 226868 revolves around this black hole in 5.5 days.
The black hole draws in gas from this star. The gas that piles up in the accretion disk around the black hole becomes so hot that it emits X-rays. In addition, the infalling gas also forms a jet.
This jet collides with the interstellar gas. The shock wave that this forms can be seen in this image.

Image Description and Details :

All of the data acquired to produce this image was shot during the Lunar eclipse's totality. The image was shot on the east coastline of New Zealand (Bortle 2) on the 26th of May 2021. This eclipse was special, not only because it occurred during a supermoon, but also because of its positioning in the night sky. Gear includes: Nikon Z6 and Rokinon 135mm F2, mounted on an iOptron Skyguider Pro. Exposure settings: Rho Ophiuchi - 16 x 30s, ISO 1600, F2.8. Lunar Surface: 1/5th of a second, ISO 1600, F2.8.

Image Description and Details :

Abell 39 is a faint nearly symmetrical planetary nebula in Hercules. Exposures for Abell 39 taken from 3 April to 21 May 2021 from my backyard Observatory. 32.1 hrs of exposure time consisting of 160min of Red and Green, 140min of Blue, 700min of Ha and 760min of OIII. I used my Stellarvue SVX 152T with a ZWO ASI 6200 camera. Control was with Voyager automation. The images were taken using 1x1 binning for a resolution of .64 arcsec/pixel. The exposures were also done using a 1/2 frame ROI.
Abell 39 is the 39th entry into George Abell's catalog of planetary nebula. Within this field are an enormous amount of background galaxies, probably more than foreground stars. The image is a crop of a much larger field of view.

Image Description and Details : Sh2-155 or Sharpless 155 is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. Images showing a curved arc of emission nebulosity corresponding to a cave mouth (roughly center of image) gives rise to the popular moniker "Cave Nebula". Sh2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth.

Image Title: Horseshoe Crater in Mare Crisium

Image Description and Details : This is not the most spectacular image I have captured of the Moon, but what transpired with it is.

NASA has awarded Firefly Aerospace of Cedar Park, Texas, approximately $93.3 million to deliver a suite of 10 science investigations and technology demonstrations to the Moon in 2023. The delivery, planned for Mare Crisium, a low-lying basin on the Moon’s near side, will investigate a variety of lunar surface conditions and resources. Such investigations will help prepare for human missions to the lunar surface.

My friend Brian Hamilton Day from NASA Ames Research Center presented me with a challenge to try and capture Horseshoe Crater in Mare Crisium, where the Firefly mission landing is mentioned above. Brian then sent this image to the Chief Engineer at Firefly Aerospace and here is a segment of that conversation.

*** I brought Horseshoe Crater forward as a challenge object to the Amateur Astronomy Selenology Project, a group of expert lunar imagers. With its small diameter, low profile and no significant albedo difference from the surrounding terrain, this is truly a very challenging subject of terrestrial imaging. It is only visible when close proximity to the terminator results in greatly prolonged shadowing that accentuates its modest topography. Gary Varney, one of the leaders of the group, responded successfully with the enclosed image. Gary captured this remarkable image at the 96% waning gibbous phase using an 11-inch aperture Celestron CPC Deluxe 1100 Edge HD telescope, an Altair IMX174 Mono camera, and a 3X barlow lens. With this demonstration that this is indeed a possible target, the challenge of tracking down this remarkable landform could add to the public interest and involvement in this very intriguing area, especially if it becomes the target of a landed mission. A current effort by the Solar System Treks development team in conjunction with Cal State University Los Angeles is adding functionality to the Moon Trek portal facilitate ground-based telescopes and amateur astronomers tracking down and identifying a wide range of lunar landforms such as this. ***

Firefly responded...

*** Thanks Bryan, that’s a fantastic image! We are discussing the possibility of operating some hours into the lunar night. This image shows that even after our lander is in the dark, we’ll still be able to see the horseshoe for a period. We’ll have to discuss an exact definition of “dusk” with our Contracting Officer.***
