Fiery dust lanes over a lake of blue stars: HST+JWST image of IC5332 by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/dim-spir ... -and-jwst/

IC 5332, also known as PGC 71775 is an intermediate spiral galaxy about 30 million light-years away in the constellation Sculptor. IC 5332 is a delicate spiral galaxy that is unusually faint and beautifully symmetrical. As viewed from earth it is nearly face on. It has a very small central bulge and open spiral arms accounting for its classification (SABc). The galaxy lies in the direction of the celestial south pole.

I wanted to highlight the JWST dust lanes more clearly, so I decided to stick to truer color and make the observations red. The result was something a lot more striking, which I like! It’s awesome to see how the dust lane spiral angle and the stellar spiral angle don’t match – not sure why this is.

VdB 152 (LBN 531), HH 450, B 175, DeHt 5 (LBN 538) and SNR G 110.3+11.3
https://www.mauricetoet.nl/DeepSky/i-KqcvbxC/A
Copyright: Maurice Toet This is an HαRGB image, using my ZWO ASI294MM mono camera with an Hα filter at F=500mm f/2.8 and my Nikon D810a at F=770mm f/4.3 for RGB (actually one-shot colour). The Hα data, acquired at home (Zoetermeer), and RGB data, acquired in Grandpré, were combined in Astro Pixel Processor. Post-processing was performed in Adobe Photoshop.

The bright red veils are remnants of supernova G 110.3+11.3. VdB (Van den Bergh) 152 is the blue reflection nebula on the 'head' of the brown Bok globule B (Barnard) 175. The small red feature just right of VdB 152 is HH (Herbig Haro) 450, being a jet emitted from a newly forming star. The isolated bright red 'shell' is DeHt (Dengel-Hartl) 5, a dense part of the interstellar medium ionised by a hot white dwarf star.

Exposure time: 19 hours, 15 minutes (136x 300" Hα, 95x 30" OSC | Optics: Takahashi ε-180ED f/2.8 & f/4.3 | Cameras: ZWO ASI294MM Pro (B 2x2, G 120, T 0 °C & -15 °C) at f/2.8 & Nikon D810a (ISO 800) at f/4.3 | Acquisition: ZWO ASIair Pro | Filter: Baader Planetarium Ultra-Highspeed | Mount: Astro-Physics Mach1 GTO | Location: Zoetermeer, Netherlands (Hα), Grandpré, France (OSC) | Date: 18 & 20 August 2022 (Hα), 26, 27 & 28 August 2022 (OSC)

The galaxy NGC 6946, also known as the Fireworks Galaxy due to the large number of supernovae discovered within it, is a beautiful spiral galaxy located about 10 million light-years away. Nearby, but only apparently, there is a cluster of stars: NGC 6939. In reality, this object is part of our galaxy and it is enormously closer, at only 3800 light-years from us. This area of sky, between the constellations of Cepheus and Swan, lies in the galactic plane. Because of this, both objects are immersed in a faint dust nebula; in fact, the sky background of much of the image appears gray and not perfectly dark
