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.***

On the night of May 1, two tiny comets made a close encounter in the Earth's night sky. The smaller one on the left is C/2020 T2 Palomar, while the larger one on the right is C/2020 R4 ATLAS. In fact, they were still hundreds of millions of kilometers apart but happened to appear in the same direction of the Earth's perspective. The two comets went their separate ways soon after, and it will be a long time before they meet each other again.

Cederblad 111 is a blue reflection nebula in the southern constellation of Chamaeleon and is part of one of the closest dark cloud complexes to the earth at only 550 Ly distance away. Cederblad 110 is the accompanying reflection nebula in this wide field image Both are part of Chameleon I molecular cloud complex. The small, elongated, bright red objects at the center of the image are Hebrig-Haro objects (HH 49-50), which form from a collision between ionized jets of gas ejected from newly born stars and the surrounding cloud. This area of the sky is rich in dust and Ha creating new bright stars within the dusty shroud. 40 x 900s Stellarvue SV80ST - ASI6200 - AP1600 Processed entirely in Pixinsights Imaged from Obstech Observatory El Sauce, Chile

Image Description and Details :

The two images on the left date back to 23 June 2020 while the two on the right were made on 14 May 2021, the latter clearly highlight the presence of the nova V1405 Cas discovered on 18 March 2021 and which at the time had an approximate magnitude of 9 , 6 but in the last few days the magnitude has unexpectedly risen to about 5.2. It is hypothesized that the star that produced the nova is the eclipsing variable CzeV3217 located at a distance of about 5,500 light years from the Solar System, V1405 Cas was initially classified as a "classic nova" or the result of an explosion that occurred in a binary system consisting of a star and a white dwarf but further studies are currently underway.
In order to show more details the original frames were heavily cropped.
