Daniel FischerThe James #Webb Space Telescope would probably not be your first choice for observing the large open #StarCluster of the #Pleiades but the authors of the paper "JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium" - https://arxiv.org/abs/2602.03672 - did it anyway, to study the turbulent energy cascade in the CNM the cluster happens to move through right now. Here is what they saw, with the NIRCam and the F335M filter - for the four cuts from the JWST pictures at the bottom in detail see fig. 2 of the paper.
PicturavisAround the Flaming Star
This image depicts a region in the Auriga constellation, including multiple deep-sky objects. I aimed for the Flaming Star Nebula (IC 405) and the Tadpole Nebula (IC 410), but the wider framing of the lens includes the star clusters M36, M38, and NGC 1907, as well as the nebulae IC 417, Sh2-235, LdN-1512, LdN-1522, and LdN-1523.
As with my previous DSO images, this image was taken without a tracker but with sporadic manual tracking with a standard DSLR setup with a 105 mm macro lens. This time I used 1360 × 2 s frames, resulting in 45 m 20 s exposure time.
This relatively short integration time is near the limit of what is possible for me, as the large number of frames requires a lot of storage during processing (>700 GB in this case). Details of the nebulae are not obtainable with this method, but the general shape can be seen. It also only works well with larger objects, as the relatively wide tele, noise, and resolution limits do not allow capturing details of smaller DSOs.
Despite the limitations, it is fun to experiment without a tracker and see what is possible.
The workflow included #Siril, #GraXpert, #StarNet, and #GIMP.

A cosmic-ray loaded nascent outflow driven by a massive star cluster - Nature Communications
Massive star clusters have been suggested to contribute to the acceleration and transport of cosmic rays in our Galaxy. Here, the authors present the detection of a cosmic-ray loaded outflow from the prominent massive star cluster Westerlund 1.

Still learning how to recognize constellations and the sky was clear tonight.
Jupiter and the Pleiades open cluster have become my anchor the past few nights.
Photos adjusted for visibility and clarity.

Good News Community🌌✨ Stellar surprise! The Pleiades (Seven Sisters) star cluster is 20x larger than we thought—thousands of hidden siblings uncovered via NASA’s TESS & ESA’s Gaia. A cosmic family reunion reshaping our view of the galaxy! Read more: https://www.discovermagazine.com/the-seven-sisters-star-cluster-is-20-times-larger-than-we-thought-48250

Marcus 🦀 BorkenhagenSo, here's another one.
This is basically the same as the last one, but I *cheated* in processing by using the Mantiuk Tonemapping operator as provided by #GIMP.
Fun fact about this; my wegde was in use at the time, so I just put the #Seestar out on its mini tripod and let it do a Mosaic of 1.4x the target area using 10s exposures;
* wanted a mosaic to have more pixels to play with
* it would cover the area regardless of eq/alt-az mode
Turned out really well, I think.
For comparison, the non-tonemapped variant is here: https://hachyderm.io/@fritschy/115511302281409427
