Another object from this nice catalogue of faint nebula.

Long integration of 53 hours using two narrow band filters mainly, searching the limits of the equipment and my own process skills.

It's not a popular target probably because is difficult and usually is not showing so much detail due to the high dynamic range, the core is bright, really bright compare with the faint surroundings.

Sh2-235 is the most central and brightest nebula of an H II region known as G174+2.5; it is observed in the direction of the northern part of the Aur OB1 association and includes the nebulae catalogued as Sh2-231, Sh2-232, Sh2-233 and Sh2-235, identified as individual nebulae in the 1959 census of H II regions. Although in the optical images they appear as distinct nebulae, in reality they all belong to a single giant molecular cloud, of which some parts appear illuminated by young and hot stars. This cloud is located in Perseus' Arm at a galactic latitude that places it slightly off-center with respect to the center of the galactic disk; the distance measurements indicate a range between 1600 and 2000 parsec, so it is normally indicated as about 1800 parsec (5870 light years).

Using my data from last January, I reprocessed Orion using Pixinsight.

astrocamp.eu/en/messier-81-widefield-march-25/

In March 2025, I embarked on an astrophotography project focusing on Messier 81 and its neighboring galaxies. I captured the luminance data at the Hohen List observatory in the Eifel region, while the RGB channels were taken earlier from my home in Koblenz. Combining these, I achieved a total exposure time of 6 hours and 20 minutes. The resulting widefield image prominently features Messier 81 at the center, with Messier 82 to its left, the Garland Galaxy below, and NGC 2976 in the upper right. This project served as a testament to the capabilities of my telescope-camera setup, delivering impressive results even with a relatively short integration time.

Around 600 shots with 70-200mm exposure of 0,8 seconds.

Processed stacked in Pixinsight.

No equatorial or azimutal mount.

Using the MARS data in the latest PixInsight I got the best result I've gotten from M45.

A Hydrogen-Alpha + Oxygen III + Sulphur II Narrowband widefield image of the Cygnus Wall. The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to the star Deneb. The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.

The Cygnus Wall:

The Cygnus Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall has the most concentrated star formation in the nebula. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). The nebula complex is estimated to be about 1,800 light-years from Earth.

"M101 is a large galaxy, with a diameter of 170,000 light-years. By comparison, the Milky Way has a diameter of 258,000 light years. It has around a trillion stars, twice the number in the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small central bulge of about 3 billion solar masses.

M101 is asymmetrical due to the tidal forces from interactions with its companion galaxies. These gravitational interactions compress interstellar hydrogen gas, which then triggers strong star formation activity in M101's spiral arms that can be detected in ultraviolet images. "

The Trifid (M20) is a combination emission (red) and reflection (blue) nebula that is located in the constellation Sagittarius. It gets its name because the main section of the nebula is divided by dust lanes into roughly three parts.

Taken over two nights from a relatively dark site on the slopes of Palomar mountain, this image consists of 1022 sub-exposures that were each exposed for 5 seconds using an uncooled QHY5-III 178C camera and a Stellarvue SV80ST2 telescope (the latter operating at f/4.8 using a 0.8X reducer/corrector, total exposure integration time about 85 minutes). Using such short exposures greatly simplifies the image capture process since there was no need to guide the Celestron AVX mount that carried the scope and camera.

Image capture was done with SharpCap, image processing was done in PixInsight and Photoshop CC2015.

This photo is best seen against a dark background or in the Flickr light box at full size (1920 x 1242 pixels).

This is visible in Scorpius. At about 5,500 light years away the Cat's Paw is an emission nebula with a red colour that originates from an abundance of ionized hydrogen atoms.

Taken with iTelescope.net T12 (Takahashi FSQ-ED 106mm, SBIG STL-11000M / Siding Spring, Australia) in mid December.

60 minutes of data: 3 5 minutes exposures each of Luminance, Red, Green, Blue.

Processing in FixFits (remove bright rows), PixInsight (StarAlignment, ImageIntegration, ChannelCombination, STF / Histogram, LRGB), Lightroom (image enhancement and cropping).

Last nights clear spell wasn't actually as good as promised, but decent enough to capture 3 hours of OIII. The sky was milky and damp, but there was decent seeing towards the zenith. Rain has set in again and with the moon looming it may be a while before I can add any more OIII.

The colour mapping is pretty standard, Ha to red and OIII to blue and green.

Total exposure time 8 hours, shot using an Altair Astro 6" RC, Astrodon narrowband filters and an Atik 314l+. Processed using Pixinsight and CS5.

This is a very small part of the whole area as its end of season for this part of the sky no way I could do a whole panorama. The Blue is Oxygen that all part of the Super Nova remnant What you are looking at is in Gum 17 area also not far from the Pencil Nebula. This whole area has some great targets for next year, this was some thing I was looking forward to being able to do with the filters as I knew the blue stood out.

It is always fun to do a bit of astroimaging on a relatively warm December evening.

Central to this image is a dark cloud of dust and gas resembling a horse’s head, known as the Horsehead Nebula (B33). This nebula is further enhanced by a bright H alpha emission nebula, which is part of the Orion molecular cloud designated IC434. Adjacent to the Horsehead Nebula is the Flame Nebula (NGC 2024), an active star-forming region containing hundreds of low-mass stars. Approximately 86% of these stars have circumstellar disks, which are believed to be an early stage of planetary system formation. Notably, the bright star on the edge of the Flame Nebula is Alnitak, the easternmost star of Orion’s Belt.

The image was obtained with 30, 2 minute images using a RASA8 telescope, ASII2600MC Pro camera, and an IDAS NBZ II dual narrowband filter. Processing was with Pixinsight and PS.

What started out as a question became a small marathon. I was getting shadow /reflections of the filters in the shot. So it became full clean down mirrors and filters. once put together I did a NB night and a RGB night to see if all had gone, happy to say its all clear.

What better way to really see so I did 5 nights of NB in total about 130 shots per filter. This is a Hubble SHaO pallet. One thing that showed up in those 5 night 2 am in the morning mount would disconnect. It would restart straight away once I got the port recognized. Turns out the fitting for the EQMOD cable for the mount was not firm even if the screws where. Two small slithers of a wall plug on the screws the whole thing is a tight as a drum and ran all night.

Now who cant see the chicken running Bottom left cant miss it. Still cant get over the detail in the shot.

The Orion Nebula, also known as M42, is a diffuse nebula located about 1,344 light-years away from Earth in the constellation Orion. It is a well-known stellar nursery, where new stars and planetary systems are forming from collapsing clouds of gas and dust. Spanning about 24 light-years in diameter, it is one of the closest and largest regions of massive star formation visible to us.

At the heart of M42 lies the Trapezium Cluster, a young open cluster of stars. This cluster consists of four main stars arranged in a trapezoid shape within a 1.5 light-year diameter. Two of these stars can be resolved into binaries, bringing the total to six visible stars in the cluster. These stars, along with many others in the nebula, are in the early stages of their evolution. The Trapezium Cluster is part of the larger Orion Nebula cluster, which includes about 2,800 stars spread over 20 light-years.

Near the top of the frame is Sh2-279, the Running Man reflection nebula.

All the surrounding dust and lanes of dark-nebulae are part of the Orion Molecular Cloud complex.

This was a moderately complicated image to make, being an HDR:

300 lights at 1s - for the stars, especially the trapezium cluster in the core

100 frames at 180s for the detail in the dust

20 frames at an intermediate 30s for a smooth blend

My first wide field Galaxy photo, 6 months after getting my first Telescope (a small inexpensive GSO 6" Newtonian Reflector) .

Ancient light from a Galaxy far, far away (situated 11.42 million light years from Earth).

The Sculptor Galaxy, also known as the Silver Coin or Silver Dollar Galaxy (NGC 253), is an intermediate spiral galaxy in the constellation Sculptor. It is a Starburst galaxy, which means that it is undergoing a period of intense star formation (well it was 11.42 million years ago, as the light took that long to reach us).

Recent research suggests the presence in the centre of this Galaxy of a Supermassive Black Hole, with a mass estimated to be 5 million times that of our Sun.

Photographed at the West Rand Astronomy Club's Annual Star Party at Mountain Sanctuary Park (North-West Province, South Africa). A special thank you to Neil Viljoen from "The Telescope Shop" for his assistance.
