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.

Image Description and Details :

Jones-Emberson 1, a.k.a the Headphone Nebula, is a northern planetary nebula. It is also catalogued as PK 164+31.1. It is located about 1600 light years away in Lynx. The red and green glows are mainly due to emissions from hydrogen and oxygen atoms, respectively. The nebula’s brightness is listed as magnitude 14.1, but it is relatively large, so the light is spread out and it has a very low surface brightness.

This image includes galaxies that lie millions of light years away, thousands of times further away than the nebula. Look for streaks and smudges that look obviously different from the sharper, rounder stars.

Image Description and Details : Flame Nebula (Ngc 2024) made by Team ARO in South Portugal . This Team is composed of Francis Bozon, Jean_Luc Gangloff, Stéphane Gueyraud.The Flame Nebula extends over about 12 light years. Alnitak (Zeta Orionis), the easternmost bright star in Orion's belt, energises the nebula. The intense ultraviolet radiation from this blue supergiant ionises the hydrogen atoms in the nebula.Gas and especially dust in front of NGC 2024 absorb the light from the nebula and form the dark ribbon seen in the visible light images.These acquisitions were made with Scope Fsq 106, on Eq6 Pro and ZWO Asi 1600MM camera. The exposure times are as follows:-Ha= 201 x 180''-R = 73 x 150 ''-V = 92 x 120 ''-B= 94 x 120 ''That is a total time of about 19.15 hours.

M83 is a barred spiral galaxy located 15.21 million light years from Earth in the southern constellation Hydra. With a diameter of about 55,000 light years, it is roughly half the size of the Milky Way. M83 is one of the nearest and brightest barred spirals in the sky.
One interesting feature of M83 is the high number of supernova's observed during the last century.
Newer generations of stars in M83 form mainly in clusters on the edges of the dark, spiraling dust lanes. These bright, young stellar groupings are only a few million years old and produce massive amounts of ultraviolet light. That light is absorbed by the surrounding diffuse gas clouds, causing them to glow in pinkish hydrogen light.
