ISS trails Over the Great pyramid (15 Sep 2022, 18:58 Cairo time )
the great pyramid of Giza is one of the oldest wonders on the earth and it is considered a symbol of ancient civilization,
The ISS is one of the symbols of modern civilization and it was built using current knowledge and science, as the great pyramid contains the knowledge of ancient people.
From the past to the modern into the future
ISS rise from Southwest and got higher to Northwest from (18:58 to 19:02) around 4 mins then it went outside the frame, also you can find some star trails in the same period of ISS movement over the great pyramid

When I first started this project, I thought that the Dumbbell Nebula was going to be an easy one to process. I was looking to get the outer fringes (Ha/OIII) of the nebula to show up with some sort of detail. After an initial go with 40x300s on the Ha, I went back and captured 600s subs. That brought out the outer shell. Further processing of the LRGB data, I was able to get the white dwarf in the center to show itself. With a tad over 20 hours on this target, I can say that I am pleased with the outcome.

NGC 7331 - Deer Lick Group

Sometimes things go the way you want and i couldn't be happier with how this image of the NGC 7331 (Deerlick) group ended up looking. i've struggled with Galaxies on my set up. never being quite satisfied with the focus or the detail but on this ocassion it all seemed to come together.

Tarantula Nebula and Surroundings in the Large Magellanic Cloud, duo-narrowband OSC.

The nebula consists of a cloud of interstellar gas—principally hydrogen—lit from within by young,
hot stars that ionize the gas around them.
As the atoms in the gas recombine, they emit visible light.
The total mass of the nebula is about 1,000,000 solar masses, and its diameter is 170 parsecs (550 light-years),
making it the largest region of ionized gas in the entire Local Group of galaxies.

So, I couldn't find much info on this target in Stellarium, so I'm calling this the Ring nebula of Cygnus. Though I was told this target is called LDû 2, named after Pascal Le Dû who discovered it. There wasn't a whole lot of OIII, so did this one in the HSS color palette, along with RGB stars. Hope y'all enjoy!

NGC 6544 in Sagittarius

NGC 6544 is located in the western part of the constellation of Sagittarius, on the edge of a rich star field. Easy to find since is just 50' towards the southeast of the well known Lagoon Nebula. It can also be noted from dark skies with 10 x 50 mm binoculars as a small white spot like a misty star.
NGC 6544 was first observed by British astronomer William H erschel in 1784 who watched through his 18,4 inch reflector. He described as a fairly bright and large object circular and resolved into stars. As per today it is not clear whether it formed with the Milky Way or came from else ware.

As always, I want to know "where in the sky" this is. "Fornax" is not enough of a clue. What are those two prominent galaxies at center left? What are their designations? If you don't know that, maybe you can tell me the designation of the bright orange star to the lower left of them (or, to the southeast of them, if north is up). And if you don't know the designation of the bright star either, then perhaps you can tell me the coordinates of the image, and maybe, maybe the coordinates of the two brightest galaxies?

Thanks a lot for your help! And thank you so much for this splendid image! Rarely has a "starless image" been such a good idea!

Ann

Thank you very much Ann, I'm working on a video that zooms into the area on the sky and explores the Hubble Ultra Deep Field galaxies, in the meantime the coordinates for this image are RA: 3 32 39.046 Dec: -27 47 28.96
The two brightest galaxies are PGC 749724 and PGC 749439.

Thanks a lot!

My software rejected the PGC designations, even though it does accept PGC galaxies. My software did show me two PGC galaxies nearby, PGC 12971 and PGC 12976, but they are 15th magnitude objects. Simbad Astronomical Database recognized PGC 749439 and called it a 17th magnitude active galactic nucleus, but it didn't recognize PGC 749724.

The coordinates that Simbad gave for PGC 749439 are RA: 03 33 20.6036338704 Dec: -27 49 10.267218948.

Hi Ann, I completed a zoom-in video of the Hubble Ultra Deep Field area, so here you can see where in the sky it is:

The Lion Nebula (Sh2-132) and two bonus planetary nebulae

Sharpless 132 (Sh2-132) goes by the common name of the Lion Nebula and it straddles the boundary of the constellations Cepheus and Lacerta. It is primarily an emission nebula with several embedded small dark nebulae and is estimated to be at a distance of roughly 10,000 light years from Earth. The core of Sh2-132 includes pillar-like structures, Bok globules and the characteristic oxygen-rich stripe through the head of the Lion.

In the large field of view presented here there are also two small planetary nebulae that are well resolved. They are labeled PK102-02.1 (Abell 79) on the lower left of the image and PN G101.5-00.6 on the right of the image. Abell 79 is a planetary nebula in Lacerta comprising an irregular and broadened oval-shaped ring from which faint oppositely-directed lobes emerge. The characteristic shape is responsible for its name of the 6 nebula. It was discovered in 1947 by Rudolf Minkowski but only classified as a planetary nebula by George Abell in his1955 catalog.

PN G101.5-00.6 is an oxygen-rich young planetary nebula included in the IPHAS catalog of new extended planetary nebulae. It has a bipolar shape with a second fainter arch extending South of the main lobe.

Orion Nebula, The Horsehead Nebula, and surroungings

This region, like possibly many of you, is the reason why I started photographing the night sky.
One and a half years ago I took my first poor, noisy and undefined picture of this region, that was my
first astrophotography. Since then I never took the time and had the courage to try it again due to the fear of
a new frustration. Today I am proud of my result and so I share it with you.

Nebulae are clouds of dust and gas that represent either end or the beginning of a star’s life cycle.
Some are places where stars have died, others where stars are forming. The Orion Nebula is the latter.

At only 1,344 light-years away, in Orion (the Hunter) constelation, the Orion Nebula is the closest and one of the brightest nebulae
visible from Earth. This means it can be seen with the naked eye up to mid-March when viewed under
dark skies.

The Horsehead nebula is a dark nebula composed of interstellar dust that blocks starlight
as well as the ionized gasses which comprise IC434
(the bright red emission nebula that is the backdrop of the Horsehead Nebula).
The Flame Nebula on the left is a reflection nebula that is lit
by nearby Alnitak (one of Orion's three belt stars).
