Perhaps the most famous star cluster on the sky, the Pleiades can be seen without binoculars from even the depths of a light-polluted city. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and closest open clusters. The Pleiades contains over 3000 stars, is about 400 light years away, and only 13 light years across. Quite evident in the above photograph are the blue reflection nebulae that surround the brighter cluster stars. Low mass, faint, brown dwarfs have also been found in the Pleiades.

This object was imaged from my southern Australian observatory, with a maximum elevation from the horizon between 30 and 35 degrees..

Hanging in the sky like a bejewelled Christmas treee we can find the Pleiades Cluster. Also known as Messier 45, the Seven Sisters or Subaru (Japan), it's an open star cluster dominated by hot blue and extremely luminous stars that have formed within the last 100 million years.
It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The dust surrounding the stars forms a blue reflection nebula around the brightest stars causing the entire region to appear in a blue glow surrounded by a deep cloud of dark, reddish brown dust and gas.

Messier 45 (Pleiades) is one of the most iconic deep sky objects in the night sky, and this reflection nebula is one of my all time personal favorites objects.
Thanks for looking!

Aglomerado aberto das Plêiades (em sua maior parte). Nas próximas oportunidades, tentarei fazer mais frames para obter melhores registros finais. Enquanto não chegam as novas correias (maiores) que encomendei, adaptei uma correia da minha montagem anterior em um dos eixos. Houve relevante melhora no funcionamento. Vou tentar adaptar uma dessas correias também no outro eixo para testes até chegarem as novas.

This is a difficult target with moderate amounts of light pollution, from where my mount is setup I only get a ~2-3 hour window to shoot the nebula this time of year and give the light pollution in the area I really need to get 15 hours of integration or more. This is a stack of 87 x4 minute exposures for a little less than 6 hours total, if I get some clear skies during the new moon phase I want to get at least double that to bring the noise down and more of the details out.

I've been looking forward to this conjunction for months - ever since deciding to get into astrophotography last year.
In the event, many practice runs shooting the Pleiades were useful, if not for image data as I'd hoped but at least for getting familiar with setting up the tracking mount and camera in quick order to catch a few photons during a committee meeting.

I never posted this from my trip to Win Green, originally I didnt think that there was much detail or colour to pull out of the images but was really impressed with it in the end.
I've spent some time re-editing a few of my recent images in PixInsight, I've managed to pull out quite a lot more from them!

The Pleiades star cluster is also known as the Seven Sisters, and as Messier 45. It is a prominent object in the night sky with a conspicuous place in ancient mythology. The cluster is among the nearest to Earth, and the most obvious to the naked eye.
The Pleiades (Seven Sisters) is an asterism and open star cluster containing hot B-type stars in the constellation Taurus. At a distance of 444 light years, it is among the nearest star clusters to Earth. The two reflection nebulae associated with the Pleiades are NGC 1435 (Merope Nebula -- lower right) and NGC 1432 (Maia Nebula -- upper right). With enough exposure time and careful processing, however, it just looks like dust everywhere.

The planet Venus wondered into the open star cluster of Pleiades last night. Pleiades is also known as the Seven Sisters. There was too much moon last night to see the clouds of dust and gas that surround the stars in the cluster. Adding to the challenge is the huge difference in brightness between Venus and the stars. My image was photobombed by a passing satellite (NOSS 3-7 r), which adds a little interest

Second of two shtos from this night. This night was unfortunately slightly less transparent than the other night I was out (at least in this part of the sky), but still had ok seeing. At 340 mm, I was only able to manage 60 second exposures with reasonable reliability given the tracking accuracy I was dealing with. 19 of the 30 exposures I took proved usable, and I more or less got the shot I wanted out of it, given the alotted time. Nikon Z6III settings: 340 mm, f/5.0, 60 s, ISO 3200. Stacked with DeepSkyStacker.
The Pleiades is a an open star cluster approx 444 light years away and is located in the constellation Taurus . It is one of the brightest star cluster in the sky, easily visible even in some moderate light polluted areas. After sunset just look towards the east and you can see this beautiful star cluster.
