When you look at the Rosette Nebula, you're seeing raw materials making a transition into stars, planets, and eventually life. With a balance between creation and erosion, these same processes formed our sun. Every atom of oxygen, carbon, and iron in our bodies came from environments like this. Looking at the colors, we're seeing orange hydrogen gas, (mostly) pink dust, and blue light coming from hot stars that emit so much radiation that they burn away the hydrogen from the center.
The Rosette Nebula goes by a few names including the less than exciting "Caldwell 49". With the circular shape, I think it should have gotten something more fitting like "Homer's Donut". At least the state of Oklahoma was quick to adopt it as their official astronomical object.
Images for this 2x1 mosaic were provided by iTelescope.net. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets with the rights to use them and webinars that show how to process them. I was planning on shooting the Rosette Nebula someday and so I was very happy to see the webinar and the images from that same area. It was extra nice that they included images that came from 3 hours, 35 minutes of capture time - giving me potential for very good image quality.
I did my processing with Astro Pixel Processor, Photoshop and Topaz Denoise. Star spikes are natural.

M 81 and M 82 are truly „iconic“ deep sky objects! I spent more than 17 hours on capturing this widefield, comprising „Bode’s Galaxy“, the „Cigar Galaxy“, some smaller galaxies nearby (like NGC 3077 and NGC 2976) and the galactical cirrus, that consists of dust within our own galaxy's disk.
To create a picture from RGB, H-Alpha and Luminance data and keep the balance between both, the bright galaxies and the faint cirrus, was a real challenge and took me many, many hours. Hope you like it!

Comet 67P/Churyumov-Gerasimenko passes through the constellation Gemini on three consecutive nights: November 6, 7, and 8, 2021 (right to left), near the closest it will come to the Earth in its orbit. This is the brightest comet in the sky right now, though still not really very bright at all. ESA's Rosetta spacecraft orbited Comet 67P and the Phillae probe landed on it back in 2014. The orange-ish star at upper right is upsilon Geminorum, one of the bright stars in Gemini.
This is a composite of multiple exposures taken over several hours on each of the three nights. These were combined to produce a panoramic view of the background and of the comet on each night.

The Butterfly Nebula (IC 1318) in the constellation of Cygnus is one of the most popular objects in the summer sky. Surrounding the supergiant star Sadr (Gamma Cygni), there is a variety of gas and dark nebulae that make this area incredibly fascinating! I had heard that there is a relatively high amount of SII emission in this region, and indeed, that turned out to be true. I captured a total of 9.5 hours of exposure at f/2, to create this SHO version.

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!

✨ 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. ✨🌍

VdB 14 & 15 (left in the picture) are two very beautiful reflection nebulae, which also contain a few reddish emission components and belong to an even larger dust cloud in the inconspicuous constellation Camelopardalis. VdB 15 is the larger, lower area of the nebula and surrounds the star CE Cam, a variable supergiant. VdB 14, the upper part of the nebula, is located near the star CS Cam, which is also a supergiant. The distance to earth is around 3,000 lightyears.
The open star cluster Stock 23 can be found on the right in the picture and is also a nice object for visual observation. Its distance is estimated at 1,240 lightyears and it is surrounded by several spectacular dark clouds. It is embedded in the large but faint emission nebula SH2-202, which extends over the entire right half of the picture.

This is a panorama of the wonderful "Heart and Soul Nebula". The session was split in three separate panels, recording about two hours data with the RASA 8 for each. Captured with the IDAS NBZ Duo-Narrowband-Filter (Ha & OIII), processed as a bicolor image. RGB stars were recorded in a seperate session. I tried to bring out as much detail and structure as possible (especially in the area around the heart nebula) and to make the colors "pop"! Hope you like it!

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.
84 frames, each 90 sec. (just over 2 hours total exposure), processed in Astro Pixel Processor, once to register on the comet, again to register on the stars, processed in Lightroom and composited in Photoshop.

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."

Some may see this as nothing more than dust and gas. That may be true but with a little imagination, Orion and the Running Man are so much more. Only 1500 light-years away from earth, the Orion Nebula features stellar nurseries and glowing nebula clouds that are so bright, some people can see the glow with the naked eye. With this image, I don't just see glow, I see action and a story that unfolds.
The Running Man Nebula got its name in the 20th century and I couldn't find any interesting stories about it. So I'll leave it up to you to follow your imagination. Is the Running Man being chased or is he on a mission? Is he helping Orion (the hunter)? Is he thirsty from all that running? :-)
__________________________________________
I feel like I may have gone the long way around the world to make this image but I don't care. The Orion Constellation is mostly visible in northern skies and I shot it with a telescope in the southern hemisphere. Why would I do that? Because Chile has some really dark skies.
I planned my remote telescope session using tools at telescopius.com - deciding on a vertical, 3x1 mosaic with the T72 telescope. The T72 is a big PlaneWave 20" telescope based in Chile where they have a lot of clear nights with dark skies. I then created a plan at itelescope.net where I had the T72 shooting a combination of LRGB and narrowband frames in 3 positions. Then, after working through a few nights with cloudy skies, I had 4 nights of mostly clear skies where I captured 102 images.
I found the processing to be much more difficult than expected - mostly because of the 3x1 mosaic I chose. I've worked with mosaics before but this time with Orion and Running Man was much more of a challenge. But with improvements to Astro Pixel Processor over time and my refusing to give up (with 21 separate attempts at processing over 2 years), I finally got something I was happy with. Yay!

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.

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.

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 ...

Two star clusters within the same small field of the sky about a degree apart, but vastly distant from us and about 1,000 light-years apart from each other. M53, at upper right consists of many thousands of old stars formed at around the same time. NGC 5053, at lower left is much looser and contains fewer stars.

I never get bored of imaging the closest galaxy to our own, at 2.5 moon widths wide, it is an easy target to spot with the naked eye, really good field of view with the ASI6200 on the SHarpStar 15028HNT

I have imaged the Dark Shark Nebula before as a 2-Panel mosaic due to the field of view from a smaller sensor size, so with a Full Frame such as the ASI2400MC Pro I manage to capture the whole shark in one frame as well as the surrounding dark nebulosity

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.

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.

Last night, despite the full moon, I still put the telescope outside to shoot luminance data from M106. A total of 54x300s was recorded with the Robtics ED130 and QSI583ws. The finishing was a tough challenge due to the gradients due to the moonlight, among other things, but the result certainly did not disappoint me. I combined this data with colour data from a previous recording I took in 2020 together with Mabula Haverkamp from Astropixelprocessor. This data was only used for the colouring, and the luminance came entirely from last night. I am quite happy with this result and think that here, when the weather permits, I will venture a few more nights for a better background (hopefully with a little less moonlight). All recording info is below the photo.
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.
Total of 22 hours capture over May, June and July. Originally an HOO project, but decided to add Sulphur ii and RGB Stars.
