A Dying Star's Magnetic Racing Stripes (NGC 6894). KG Observatory, Julian, CA.

This title is from Phil Plait who has an excellent description for what may be happening here...

https://www.syfy.com/syfy-wire/a-dying- ... ng-stripes

And an excellent science paper...

https://articles.adsabs.harvard.edu/pdf ... .289..665S

Skies we're very dark and steady during this data acquisition with the FWHM on the 10-min Ha subs between 1.26" and 2.2". OIII subs varied between 1.3" and 2.2".

Nearly all the "racing stripe" energy is in Ha with the majority of OIII in the core.

A light RGB screen was placed over the top to add a bit more star color. The HaOIII combination was tuned to have nearly the same color balance as the RGB for both the stars and the nebula core.

NEW DISCOVERIES : StDr Object 32 "The Joëlle's Nebula" / Sa1 / StDr16 / StDr101 / StDr160 : the Aquila planetary nebulae parade


https://astrob.in/6bblb5/0/rawthumb/hd/get.jpg?insecure

Hi everyone, it is with great emotion and great pride that I present to you today this photo which, for me, is exceptional. It's the first time we can see the Aquila region like this.

Full is here :
https://www.astrobin.com/full/6bblb5/0/
https://flic.kr/p/2nCjPVK

Starless with annotations here :
https://www.astrobin.com/full/6bblb5/C/
https://flic.kr/p/2nCkVhW

Feel free to browse the reviews on the right to see the different images with details.
And take a look to the revisions to get a starless version with annotations and more.

There is a whole super interesting text on the technical aspect of this image and my personal story but for those in a hurry, here is a quick summary:

• New discovery of a nebula of unknown nature: StDr Object 32 which will be called the name of my mother who passed away before I discovered this passion for astrophotography and is published on her birthday.
• New discovery of a planetary nebula candidate and opening of my catalog, the SAINTY’s catalog with this Sa 1 nebula.
• 16 Planetary Nebulae or canditate + Supernova Remnant in the same field.

This photo of the Eagle's outer region shows how dynamic, interesting and beautiful an area that has been rarely visited by astrophotographers can be.

This H-alpha/OIII/RGB photo was taken in 96h45 exposure time over 32 clear nights.

This exposure time allows this region to be revealed in a way never seen before by making extremely faint structures and objects visible.

In addition to the impressive dark cloud complex on the north of the photo, the numerous blood-red HII clouds in the background, or the delicate filaments of supernova remnant W50 (visible at the top of the image), the photo contains not less than 16 planetary nebulae and candidate planetary nebulae that are still awaiting confirmation by a spectrum.

The largest representatives of planetary nebulae (and candidates) in the photo are:

• Abell 56 (bottom center of image), which is probably first visible with its central OIII core.
• On the left of the image, the Strottner-Drechsler 16 candidate PN (Planetary Nebula) with a spectrum that shows all the characteristics of a PN. And with its optical resemblance to the James-Webb Space Telescope.
• On the right of the image is Strottner-Drechsler 101 (IPHASX J191003.4+032224), whose 13.5 arc minute OIII halo was discovered with this photo.
Halos around planetary nebulae are relatively rare and usually consist of H-alpha. This OIII halo is therefore very special and was a big surprise for the team.

In the center of the image, we can see the new discovery Strottner-Drechsler Object 32 / Joëlle's Nebula.

StDr Object 32 is a nebula of unknown nature, which was photographed for the very first time with this photo. StDr Objet 32 is an arc segment marked in OIII and H-alpha around a potential white dwarf. The entire structure of StDr Objet 32 has a probable diameter of about 18 arcminutes.

We don’t know the nature of this nebula right now. The team hopes to be able to elucidate the nature of this nebula soon. In any case, this photo made it possible to obtain important information on the chemical composition and the structure of this nebula.

In total, 4 objects from the team of Marcel Drechsler and Xavier Strottner are visible in this photo of this region of Aquila.

We can also see 4 objects of the American amateur astronomer Dana Patchick from Los Angeles.

Another surprise for the team of Marcel and Xavier was to discover in my photo a possible planetary nebula unknown until now on the south of the photo. This small nebula was accepted as a candidate by Pascal le Dû and officially cataloged as Sainty 1 (Sa 1).

Messier 24 in Sagittarius

Messier 24 is one of the few particular objects of the catalogue. Under entry Nº 24, Charles Messier list a large object of 1 1/2 deg in extension, which he included on June 20, 1764, and describes it as "a large nebulosity in which there are many stars of different magnitudes." Messier 24 is not a "true" deep sky object, but a huge star cloud in Milky Way, a pseudo-cluster of stars spread thousands of light years along the line of sight.

Hello, this is my first time posting a picture.

NGC7023) Iris nebula
The Iris Nebula (also known as NGC 7023 and Caldwell 4) is a bright reflection nebula in the constellation Cepheus. The designation NGC 7023 refers to the open cluster within the larger reflection nebula designated LBN 487.
The nebula, which shines at magnitude +6.8, is illuminated by a magnitude +7.4 star designated SAO 19158.[1] It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alfirk). It lies 1,300 light-years away and is six light-years across.

"The Scars of Hurricane Michael"

The local area is coming up on nearly four years since devastating Category 5 Hurricane Michael made landfall across the Florida Panhandle in October of 2018. While the greatest devastation was along the coast, the trail of damage continued well inland, including where this picture was taken. My goal was to get out and photograph the prominent mark Hurricane Michael has left on the area by capturing a foreground with damaged timber, and the few surviving pine trees on the horizon. These impacts from Michael continue to affect the region, including the threat for large wildfires as these dead trees serve as fuel. Just this past spring, we had a large wildfire that went on for days in an area of fallen timber. For residents of the Florida Panhandle the rebuild continues but we are long from done in dealing with the Scars from Hurricane Michael.

Calhoun County near Blountstown, Florida.

I love your image and took the liberty of uploading it to Starship Asterisk*, so that others can see it.

I have a question. What is the little round whitish cyan object near top center right?

Green Flash, Purple Flash and Omega Sun inferior mirage
At 18:37 pm on August 5th, I finally caught up with the green flash! And not only the green flash, but also the purple flash and the super-beautiful Omega Sun inferior mirage! What's more important is that this time it wasn't just the camera that caught it, I also solidly "saw" the green flash! Bright green, dazzling, charming, momentary.
The big picture in this combined photo is the green flash, taken with a Canon 6D. Because the exposure is less, the green is more saturated and beautiful. However, due to the low exposure, the purple flash cannot be captured. The 3 small images on the left in the combined photo were all taken from a video shot by the Canon 600D. From top to bottom are Sun inferior mirage (Ω Sun), green flash and purple flash. When the sun falls on the sea, it creates a mirage and finally forms green flashes and purple flashes. Video link: https://youtu.be/igO_NxXejUo.
Whether it's a green flash, a purple flash, or an inferior mirage under the sun, it's all virtual images caused by atmospheric refraction. On the evening of August 5 there was just a little bit of clear skies low over the sea. At this point, the atmospheric density in the sky changes significantly. When I saw the beautiful appearance of the inferior mirage, I thought that the green flash should be hopeful. Really!!
