? A battle with the Cosmic Bat (LDN 43) by lights_and_darks_photography
A target which got a lot of attention lately here at Astrobin! When I first imaged it last year it was not so well known. However last year I had not enogh focal lenght so it was kinda small.
I found this one really hard to process, hence the title ;-)

? Galaxies Cluster in Hydra Constellation (Abell 1060) by Alexandre_Fagundes
The [b]Hydra Cluster[/b] (or [b]Abell 1060[/b]) is a galaxy cluster that contains 157 bright galaxies, appearing in the constellation Hydra. The cluster spans about ten million light-years and has an unusually high proportion of dark matter. The cluster is part of the Hydra-Centaurus Supercluster located 158 million light-years from Earth. The cluster's largest galaxies are elliptical galaxies NGC 3309 and NGC 3311 and the spiral galaxy NGC 3312 all having a diameter of about 150,000 light-years. In spite of a nearly circular appearance on the sky, there is evidence in the galaxy velocities for a clumpy, three-dimensional distribution.

? ??????????? ????? ??? ????????? ?? ????? by Makrem_Larnaout
*Under the starry sky of August 2022, the Mausoleum of Atban stands majestically, a silent witness to ages long past.

In this mesmerizing scene, the stars appear to dance around the celestial pole, tracing endless circles as if paying homage to the site's timelessness.

Each luminous streak captures the essence of time itself, transforming the sky into a canvas where past and present blend harmoniously.The site of Dougga, with its Libyan (or Libyco-Punic) mausoleum, has fascinated travelers since the 17th century.

First mentioned in 1631, this monument, rich with history etched in stone, was drawn and described by Count Borgia in the 18th century, a testament to its enduring grandeur.*

? vdB 158 in Andromeda with PK 110-12 1 by AstroNico
*Van den Bergh 158 is a stunning reflection nebula in the constellation Andromeda.
The blue young stars spread their light on the dark whisps of the dark nebula LBN 534.

The image also features a little gem in the dust on the bottom - its the planetary nebula PK 110-12 1 - can you find it?

EDIT:
IOTD 2024-08-28 - Wow!!!
That came as a total surprise.
Thanks a lot for my very first IOTD and thanks to the community for all for your likes!*

? SNR G013.3-01.3 (M24, Sh2-41 Region) by jthommes
*[size=100]Central in the image is the blue OIII emission line "sprite" structure of SNR G013.3-01.3. This SNR is in a field of Ha emission identified as Sh2-41 (also LBN 51). The distance of this SNR has been somewhat elusive with SNRCat indicating anywhere from 6,500 light years to 13,000 light years. The filamentary Ha emission below the blue sprites of the SNR and those to the left are believed to be part of the SNR shell. These filamentary Ha structures appear to be extensions of the dimmer blue OIII emissions .[/size]

[size=100]This is a busy field aside from the main attraction of the SNR. Dark nebulae are LDN 336, LDN 335 (Barn 307), LDN 321 and 328, LDN 327 (Barn 92), LDN 327 (Barn 93) and  a string of dark nebulae (Dobashi Catalog) in the lower right. Bright Nebulae seen are LBN 52 and Sh2-39.  Open clusters seen are NGC 6613 (M18), NGC 6603 (Collinder 374, Melotte 197), and  Biurakan 5.  These objects and some of the brighter stars are identified in the [url=https://www.jthommes.com/Astro/Zoom/M24_Region_FSQ_PI3_AF1_Rspl_Crp_Annotated.htm]annotated image[/url].

? Comet 62P and NGC 4411 - 61 Hours by jimmythechicken
*This was a fun little project. After getting frustrated with the disappearance of 12P Pons-Brooks and my inability to image it, I decided to find any other comet to image. I happened across Comet 62P / Tsuchinshan just as it was about to pass by this lovely little cluster of under-imaged, yet incredibly photogenic galaxies and decided to seize the opportunity. 61 odd hours of exposure later and I am quite happy with the result. This is such a rich and deep field, full of thousands of galaxies. One of the main features is the very interesting NGC 4410, a chaotic cluster of colliding  galaxies with very complex and faint tidal streams connecting them. Surprisingly I also found that in 4411 and 4411B there is quite a lot of H-alpha signal, appearing as little ruby jewels even without additional Ha data.  Anyway, hope you all enjoy!

? SH2-174 - A Labor of Love - 83+ hours on the Valentine Rose by John.Dziuba
*SH2-174, also known as the Valentine Rose, is located in the constellation Cepheus roughly 980 light years away.  It is an unusual planetary nebula in that its responsible white dwarf does not lie at the center of the nebula.   Instead it can be found near the center of the blue region.  This asymmetry is caused by the nebula's interaction with the surrounding interstellar medium.

It is a very faint target so dark skies and a significant amount of integration time is required.  My goal for this image was to bring out the beautiful details in the nebula itself, while also highlighting the surrounding dust.  This turned out to be a huge undertaking and it pushed the envelope on my patience and processing skills.

I hope that you like the result.
