A mosaic of a region of active star formation in the constellation Cassiopeia. near the center is an interesting feature known as the Bubble Nebula (NGC 7635), quite small in this large scale image. Above and to the left of that is a nice open star cluster known as M52, and to the right is another bright star-forming region, NGC 7538.

Tech: 8 tiles, each 12 5-minute exposures. ZWO ASI294MC camera, Explore Scientific FCD-100 102mm telescope, dual narrow-band filter (H-alpha, [O III]), iOptron CEM25P mount, ASIAir controller. Processed in Astro Pixel Processor and Lightroom.

The Sadr Region features a rich complex of dust clouds and glowing nebulosity set against the plane of the Milky Way. It harbours a number of notable deep sky objects. Within this capture you can see IC 1318 The Butterfly Nebula, NGC 6888 The Crescent Nebula, open cluster NGC 6910 to name a few.

The young open cluster NGC 6910 occupies 10 arc minutes of the apparent sky and has a visual magnitude of 7.4. It lies half a degree east-northeast of Sadr and may be physically related to the Gamma Cygni Nebula. The cluster contains a number of OB stars, as well as supergiant stars, including the red supergiant RW Cygni. It is the core cluster of the Cygnus OB9 stellar association. It was discovered by William Herschel in October 1786.

Collinder 419, also within the image, is a young open cluster that surrounds the massive O-class star HD 193322. The cluster has a visual magnitude of 7.60. The nearby open cluster Collinder 421 is fainter, with an apparent magnitude of 10.10.

IC 1311 is another open cluster that can be seen in the region. With an apparent magnitude of 13.10, it is considerably fainter than the others and embedded in nebulosity.

Comet Leonard (more formally known as C/2021 A1) is brightening, still not up to naked-eye visibility though unless your eyes are a lot better than mine; may be possible in binoculars. This image was made this morning before sunrise from fairly bright suburban Bloomington, Indiana (plenty of light pollution and a last quarter Moon) the tail is visible in the image for about 1 degree (about twice the Moon's diameter) and the green coma is very obvious.

note: PRESENZA DI VELATURE IN CIELO

Part of the much larger Cygnus Loop, it's the ionised gas remnants of a supernova and is around 1470 LYs from Earth. The area is VAST ( it would take me a month of solid imaging to capture it all on this camera and scope set up).

This image is a mono capture using two filters to capture light from different gases in the nebula: Hydrogen alpha and Oxygen 3. These have then been combined into Red = Ha, Blue and Green = O3.

I love shooting this area of the sky as the detail that comes out is fantastic - shame it's only visible in the summer when dark hours are down to a couple per night.

✨ Sous le ciel étoilé de l'Aubrac… 🌌

Dans la pureté du plateau de l'Aubrac, entre l'Aveyron et le Cantal, j'ai réalisé cette image au buron de la Lande du Clapier, situé à près de 1300m d'altitude. Un endroit qui, loin de la pollution lumineuse, offre un spectacle céleste d'une rare intensité.

Le ciel est une toile vivante : des nébuleuses comme celle de la Californie, qui semble s'étirer à l'infini, la majestueuse nébuleuse et constellation d'Orion, qui éclaire la nuit de sa lueur éclatante, avec sa boucle de Barnard, un cercle d’étoiles dansant dans la profondeur du cosmos. 🌠

Jupiter, la planète géante gazeuse, surplombe cette scène, tandis que les Pléiades scintillent dans leur halo bleuté.

Cette photo témoigne d’une passion profonde pour l’astronomie et la nature, un mélange entre art et science, où chaque élément du ciel trouve sa place dans un équilibre parfait. ✨🌍

I've never been that interested in imaging this region of the Milky Way with my Samyang 135 for whatever reason, perhaps because I can't resolve the Pillars of Creation in the center of the Eagle Nebula (bright emission nebula in upper right quadrant) with my 135mm lens. Even so, the wider field is full of interesting contrasting features. This area is quite bright and colorful relative to other regions that I've imaged recently, so processing was a cinch.

M13, located in the constellation Hercules, is one of the brightest and most spectacular globular clusters in the northern sky. Approximately 500,000 stars are packed into a region with a diameter of 150 light-years at a distance of 25,000 light-years. The red and blue giant stars appear in yellowish and bluish hues.

With this reprocessing, I was able to make a large number of very faint stars visible in the outer regions of the cluster, making M13 appear significantly larger compared to my first version. Hope you like it!

47 Tucanae (NGC 104) is a globular star cluster located about 13,000 light years away from Earth. The actual number of stars in this globular cluster is believed to be ~500,000 stars and the core is said to contain nearly 35,000! If planets could exist around the stars in the core of this cluster, one could only imagine what you would see in the day or night sky.

Under a frigid but very clear sky last night I tried out a new filter and was able to combine the resulting data with some previous images to produce this composite of the star-forming region known as IC 410, the larger cloud at upper left, along with the smaller IC 417 to the lower right. (For the astronomy purists, this is rotated relative to the usual north-up orientation, but I thought it looked more interesting this way (and there's no "up" in space anyway).

This rendering is a lot like many of the images from the Hubble Telescope that combine the light of the three elements sulfur, hydrogen, and oxygen into the colors red, green and blue respectively.

M106, also known as NGC4258, UGC7353 and PGC39600.

"Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole."

M33, a beautiful spiral galaxy in the constellation Triangulum. It's "only" about 2.8 million light-years away, making it the next nearest large spiral galaxy to us (just beyond M31, the Andromeda Galaxy), and part of the association of galaxies called the Local Group. Had a couple of nice clear, calm nights recently, though the moon is waxing past last quarter, and local lights add to the sky brightness.

This image was created in the past year by myself and 3 fellow astrophotographers, Sara Wager, Kees Scherer and Dominique Dierick. It's a mosaic of 8 panels that I started in 2016 and I'm slowly extending to cover more area. For every panel I try at least to get 5 hours of H-alpha data. Sara, Kees and Dominique were so nice to share their data on this region improving the quality of the image in many ways!

The mosaic was generated with the new Astropixelprocessor software which did a great job in processing and mosaicing this image.

Bonjour à tous, aujourd’hui, je vous présente la nébuleuse de l’iris (NGC7023) ainsi que la nébuleuse sombre du requin (LDN1235). Cette photo a représenté pour moi, un véritable défi technique puisqu’avec mon matériel actuel, je ne dispose pas d’un système type GoTo.

—

Il m’a fallu dans un premier temps, réussir à me repérer dans le ciel pour mon cadrage. Bien que les nébuleuses se trouvent dans la constellation de Céphée, avec un 135mm, il y a de quoi frôler la crise de nerf. J’ai donc choisi de cadrer depuis l’étoile d’Alfrik qui se trouve plus ou moins à mi-distance des deux cibles.

Here an image of the Cave Nebula, catalogue reference Sh2-155, an emission nebula in the constellation of Cepheus. It is embedded in a larger region containing emission, reflection and dark nebula. The brightest part of the nebula has an apparent magnitude of 7.7, being situated about 2400 ly from Earth. The somewhat unusual rendition shown here is derived from 6 filters in total: Hydrogen-alpha, sulphur-II and oxygen-III ultra-fast narrowband filters and g´, i´, and z-s´ photometric filters. The g´ filter (400-550nm) captures nicely the reflection nebula, whilst the i´ (700-845nm) and z-s´ (820-920nm) filters transmit infrared light at different wavelengths. The data from these two filters then needs to be colour-mapped to a visible region of the spectrum. The following colour mapping has been applied to create this particular image: g´ mid-blue, O-III cyan, Ha yellow, S-II sunset orange, i´ crimson, z-s´ purple. Stars are from the monochrome S-II integration.

The viewing conditions were not as good as was hoped (Rhön, Germany) with intermittent thin cloud and dew that fell with a particularly heavy "thud" 😉 , still most of the data was usable ...

Simeis 147, also known as the Spaghetti Nebula (SH2-240), is a supernova remnant in the Milky Way straddling the border between the constellations Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness. It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.

Same comet, same images [lights] processed differently using Astro Pixel Processor. I prefer this one.

This version of the recent Comet C/2022 E3 (ZTF), whilst zipping through the constellation Auriga a few days ago. Processed from a stack 100 light frames, each with an exposure of 60s. Astro Pixel Processor image processing application used to track the comet across the stack of images, while letting the background stars blur. The ion tail is visible here shooting off to the top left. Star trails are the 'smudges' going from bottom left to top right.

Je vous présente la nébuleuse de la trompe de l’éléphant, plus connu sous le nom de IC1396. Elle se situe dans la constellation de Céphée. Il y a 1h30 de signal, dans le futur, je prévois de faire une mosaïque de cette région absolument magnifique et riche en détail.
