I took this photo throughout the month of August and I attest to the good seeing for each light of 15 minutes with detail of the pillars. In my life I have seen such punctuality achieved with the equipment and what has been said, it is not due to good guidance and tracking, it is certified that there was a brutal sky, so I was able to take advantage of it at the resolution of 0'88" arc/pixel.
I recommend going 100% and looking at the pillar structures. As well as the adjacent structures that we can observe in the set.
For the composition I have put the SHO + RGB palette for the stars, that a priori the small ones are not visible, but if you zoom to 100% there they are, punctual. The brightest ones are noticeable by their brightness diameter and I wanted to leave them that way, without exceeding the molecular set of this beautiful structure so well known to us that Hubble photographed many years ago and left us speechless.
Anyway...A pleasure to have these objects and we hope to enjoy these skies

NGC 4244 (Caldwell 26) in H-alpha and continuum light (final version)

NGC 4244 (also known as Caldwell 26) is an edge-on spiral galaxy in constellation Canes Venatici with extended star-forming regions showing strong H-alpha emissions.

The image is calculated with and without H-alpha information. By toggling between the two variants the correlation between HII gas clouds and bluish regions (containing young stars and probably also OIII gas) can be visualized.

"Fall is Here"

October 8, 2021 in Cape San Blas, Florida
EXIF: 23 images stacked at 20 seconds, ISO 2500, f/3.5 with a Viltrox 20mm f/1.8 lens and Sony a7ii. Beach: 2 images at ISO 2500, f/5.6, and 80s.

A little over a year ago I went out to Cape San Blas, Florida to scout out locations for the then-upcoming Lunar Eclipse of November 2021, observe a thin crescent moon set with Venus, and take in the Milky Way. It was a pretty chilly evening for Florida and this late into the Milky Way season is our last chance to observe the core before it "sets" for the winter season. At this time of year in the northern mid-latitudes, the Milky Way has a beautiful vertical orientation and it can make for some beautiful scenery lined up with the right foreground so when I got to the beach to take in the night skies and Milky Way, I was elated to find this walkway in front of me that lead to the setting Milky Way! So after spending a little bit of time taking in the beautiful scene with my own eyes, I set up my camera and began shooting these untracked images.

Path to the Pillars



A high-res version is here.

A composite image to show where the famous Pillars of Creation reside in the sky.

The first two images were taken from Caradon Observatory on the edge of Bodmin Moor, an International Dark Sky Landscape and recognised Area of Outstanding Natural Beauty.

The left hand pane is a 3-frame panorama from horizon to zenith. When viewed at low-res it's not that far away from what can be seen with the naked eye from a very dark site. It was taken in 2020 when Jupiter and Saturn were close together in the sky.

The middle pane is a HαRGB image of the Eagle (M16) and Omega (M17) nebulae on the borders of Serpens and Sagittarius.

Major Lunar Standstill at Chimney Rock National Monument
AstroTours.org
Copyright: Luke Huxley Hey there!

Long time APOD enjoy-er, first time submitter! I'm excited to see how submitting works and meet the community behind APOD!

This weekend I got to experience an astronomically amazing celestial phenomenon at Chimney Rock National Monument. I got to witness the moon rise between the chimney rocks for the first time ever in 14 years and was one of the few people to have ever observed this alignment in modern times.

If I were to give a short explanation as given on the APOD website
"an astronomically amazing celestial phenomenon at Chimney Rock National Monument. Chimney Rock National Monument is located near Pagosa Springs CO and is one of Colorado’s newer National Monuments, founded in 2012. (not the newest Camp Hale that was founded this month) Chimney Rock is best known for an archeological site that is towered over by two big geologic features (two pinnacles that include the ‘chimney rock’ that tower over the archeological site). In 1987, Dr. J. McKim Malville, an Astrophysics professor at the University of Colorado, predicted, and demonstrated that, at the northern Major Lunar Standstill (MLS, an 18 year cycle where the moon can be seen the most northern point it ever will reach on the horizon) the moon would rise between Chimney Rock and Companion Rock as viewed from the Great House Pueblo. The rare phenomenon was seen from 2004 through 2007. The moon wasn't seen passing between the two rocks ever again from 2007 until October 2022 when it started the next MLS cycle. The moon will continue to be visible between the spires just about every two weeks until 2026 when the moon won't be seen rising between the rocks again for another 14 years. This cycle is thought to of had significance to the ancestral puebloans that used to inhabit the four corners region of Colorado, New Mexico, Utah and Arizona. This has been further corroborated by Dendrochronology where wood used by the ancestral puebloan builders show that building activity at the site had the same 18 year cycle of the MLS "

you can learn more and see more images I took of the alignment in the blog post I made here: https://www.astrotours.org/post/the-sta ... l-monument I think the one I put up here is the best but please let me know if you prefer any of the other ones.


Cheers,
Luke

Pleiades with 2 asteroids flying by

While processing this data, I noticed 4 RGB 'streaks' cutting through it. This indicated slow moving objects that would cut across my RGB filters as they changed over the acquisition cycle.

I then used the JPL small-body database query to find out what I captured - turns out my image was photobombed by 796 Sarita and 793 Arizona, at the same time. There are 4 streaks for 2 asteroids because the image was captured over 2 nights.

I decided to leave them in since it makes this image of the Pleiades a bit more unique

Sarita is easier to spot, even at low resolution. The 2 RGB streaks are just to the left of the Pleiades. Arizona is a lot harder. I recommend going to the full resolution version on Astrobin. It's in the middle of the blue nebulosity, and a lot! fainter.

this is another panorama from Vesterhon Iceland shot on OCT 5 2022
Story,
when the winter comes orion constellation is back to the northern night skies along with Rosette nebula , horsehead nebula ,Barnard's Loop nebula, California Nebula, and the Pleiades Star Cluster,

the vision was to capture Orion & Aurora at the same time, which is a hard mission and a rare event, all condition need to align, because Aurora is moving fast, the conditions where perfect Aurora was Dancing slow and orion part was clear skies, my vision finally came true in iceland northern lights with a deep space objects in the same frame to document a rare moments of the nights sky, this vision and capture took place in my latest photo tour trip into iceland i was waiting to orion to rise over the magical northern lights in bortle 2 skies near Vestrahorn in iceland i was saying Hello to orion and aurora from the North pole.

M33 - Triangulum Galaxy by Harley Grady, on Flickr

M33 - Triangulum Galaxy. A a great fall galaxy!

M33 is apart of the local group of galaxies that include our Milky Way and Andromeda. Like Andromeda it is visible with the naked eye in clear dark skies.M33 is also on a collision course with the Milky Way and Andromeda and in several billion years time they will all be merged into one galaxy.

Clouds, wind and stars
With my camera and my lens
Clouds and Wind by Carlos Uriarte, en Flickr

Hi,

This is a "complex planetary nebula" in Aquila. It is bipolar, and otherwise has some odd characteristics, leading some astronomers to believe that its progenitor star is a triple star (while most believe it is a double star).

Taken at Sierra Remote Observatories, Auberry, California, USA
RC Optical Systems 14.5 inch Ritchey-Chrétien carbon fiber truss telescope
Contains a total of a bit over 41 hours of exposure time, through L, R, G, B, Ha and OIII filters. Fuller explanation of object and acquisition/prodessing, as well as higher-resolution (and uncropped) images are at

The Orion Nebula (m42)

https://www.astrobin.com/5a5ms6/

This is my first ever version of the Orion Nebula (m42). I started dping astrophotography in Jun this year using my 7 years old 6se. I quickly got excited about DSO photography and setup my equipment over the late summer/early fall.
For this image, data was collected over two nights...5 hours of total integration.

Today's partial eclipse of the sun taken from inside the cathedral of San Giorgio in Modica from a window on top of the church near which there is a statue of an angel.
I liked setting the eclipse in this way to create a dramatic atmosphere that is given by the presence of this mysterious figure at the moment of the eclipse. In ancient times the solar eclipse was considered by popular belief almost as a nefarious event and was experienced in an aura of mystery and concern. Science teaches us that this is not the case and helps us to appreciate celestial events like this in the right perspective. Thanks to my camera I was able to enjoy this beautiful event of nature, so rare and so precious.
