IC 2574 in H-alpha and continuum light

IC 2574 (also known as Coddington's Nebula) is a very faint dwarf galaxy in Ursa Major. It is a member of the M81 group and contains very active star-forming regions showing strong H-alpha emissions.

The image is calculated with and without H-alpha information. By toggling between the two variants the correlation between HII gas clouds and bluish regions (containing young stars and probably also OIII gas) can be visualized.

Taken over 12 nights in early September, this rendering of what is traditionally known as the Elephant's Trunk nebula portrays a more ominous scene: a crocodile with its jaws agape (bottom left) and a shark (composed of various dark nebulae) diving out of an ocean of ionized oxygen gas while spewing dust into the crocodile's mouth.

Who will win this epic battle unfolding in the Cepheus constellation?

The image comprises 63.5 hours of integration (roughly equal parts of H-alpha, S2, and O3), and was taken from my backyard in Santa Monica, CA under Bortle 7 skies. Processing was done entirely in PixInsight, and the gear used was as follows:

Camera: ZWO ASI6200MM-pro
Scope: William Optics Fluorostar 132mm Refractor
Mount: Astro-Physics Mach2GTO
Filters: Chroma 3nm Ha/S2/O3 50mm
Guide Camera: ZWO ASI174MM-mini
Accessories: ZWO OAG-L, Pegasus Powerbox Advance

Cataloged by Charles Messier as M31, The Andromeda Galaxy was originally thought to be a nebula. William Herschel believed Andromeda to be the nearest of all the great nebulae at roughly 18,000 light years.

Edwin Hubble settled the debate of M31 when he identified Cepheid Veriable stars in photos of Andromeda which allowed for a more accurate measurement of distance. He conclucded that this nebula was not in our galaxy, in fact, it was a galaxy of its own far away from our own Milky Way. Andromeda Nebula is now forever the Andromeda Galaxy.

The following image is a 2 hour exposure (84x90 secs) taken with my AT60ED and Canon T2i DSLR taken from a Bortle 5 location Northwest of Boston, MA.

Location: Big Bend Ranch State park

Story:
I am just amazed at how dark the skies were at the Big Bend ranch state park, a beautiful state park adjacent to the more well known Big Bend national park. The park was awarded a gold tier status by the international dark sky association. It was an hour drive to this location and driving at night, without any cell service, through the winding roads, steep cliffs and crazy speed limits was itself an adventure. I had scouted this location during the day but a place so quiet and remote unnerved me a little.

In this photo, you can see California nebula and Pleiades star cluster over an abandoned home nestled among the rocks. With skies as dark as this, extracting details between the two stellar objects was easier. The interstellar dust officially called the Taurus molecular cloud is the interstellar molecular cloud in the constellations Taurus and Auriga. This region has a number of newly formed stars and its distance from our planet at 450 light years makes it possibly the closest star forming region.

I used a light panel at the lowest setting to light the house and took 2 photos to capture the foreground, to retain highlights and capture an overall brighter image.

EXIF:

Foreground:
ISO 1250 || 40 mm || f/2.8 || 60 sec [For light inside the house]
ISO 2500 || 40 mm || f/2.8 || 120 sec [For overall brighter scene]

Sky:
[ISO 800 || 40 mm || f/2.8 || 120 sec] x 49 - Almost 1.5 hours of integration

Hello,

Here is an image of the edge-on galaxy NGC891 in Andromeda that includes also the galaxy cluster Abell 347 in the frame.

This image was taken last Thursday night from my backyard near Paris (Bortle 7 sky, 20km from the Eiffel tower) with rather good seeing (1.8" FWHM after stacking).

I used a 8" f/4 home-made Newtonian astrograph on an Astro-Physics AP900 mount, with an ASI183mm monochrome camera and LRGB filters (4h of luminance, 1h30 with RGB filters, using 60sec subs). Processing made with Pixinsight.

Messier 17 Wide Field

A wide field image for a complex region covering part of the constellation of Sagittarius and Scutum. Messier 17 stands out in the center of the field. A star factory sculpted by stellar winds and radiation covering 100 light years across. Slowly stellar winds and energetic light from hot massive stars gas and dust have carved away interstellar material giving rise to the cavernous appearance and rippled shapes of the particular structure of Messier 17 also known as the Omega Nebula or the Swan Nebula.

Technical details are as follows:
Planewave CDK24 scope
Planewave Ascension L-600
QHY 461 Mono camera
Astrodon RGB filters
Total exposure was 2.75 hours
20x300 Luminance
5x300 Red
5x300 Green

The Monochrome Luminance channel was artificially colored a very slight blue to approximate the actual color based on Hubble observations. The asteroid was placed near the first exposure's position.

It has been raining like crazy for nearly 3 years here in Sydney, with only very occassional clear skies. Here is the Fighting Dragons of Ara, NGC6188, taken on two clear nights in early June 2022.

Here is WR 134, one of the things I suggested that was picked as a set of One Click Observations at Telescope Live on their SPA-2 setup.

This is 12x 600s on Sii, Ha, and Oiii. for a total of 6 hours with 2 hours for each channel, bin 2x2. The telescope is an Officina Stellare Pro RC 700, camera is FLI PL16083, and filters are Astrodon 3nm SHO.

I processed this in APP and Photoshop. I used all three channels in SHO with a modified Hubble Palette to set the stars as close to RGB as I could, then I used HOO for the nebula portions and combined them to get this. Image credit would be Scotty Bishop (me) and Telescope Live since the data is from them.

Here is Comet C/2017 K2 from July 24th, 2020. It appears to be flying through cosmic dust and clouds of hydrogen alpha, but that is an illusion since all of that is incredibly far away from our solar system.

This was from the Telescope Live CHI-5 setup, which is a Nikon 200mm f/2 lens and an FLI ML 16200 with Astrodon LRGB filters used in this shot. I processed it in Astro Pixel Processor and Photoshop.It consists of 5x 180s each of LRGB for a total of 15 minutes per channel or a total of an hour. Comets visibly move over long exposures so that explains the short duration used here.

Hello !
I’m french and I hope that you will excuse my poor English.

This is a 5h1/2 circumpolar star trails picture compiled from a 600+ sequence of 30s exposure with my digital camera (EOS 6D Mark II) mounted on a tripod and pointing the celestial North Pole. It was made during an observation night last month, Thursday 22/09, at RAAGSO (Rencontre des Astronomes Amateurs du Grand Sud-Ouest), something like « Meeting of Astronomers from Grand South-West (of France) », a big yearly star-party (at french scale : about 100 persons), located in a camp near the little village of Ambeyrac, in the valley of Lot river, between the little towns of Cahors and Figeac. The sky of this point is quite good because it is just South of a french dark region surnamed « Triangle noir du Quercy » (Quercy’s dark triangle). Unfortunately, the sky was clear only this first night and the weather was bad the next days.

Of course there are circular star trails around Polaris but also some other right trails probably from meteors (except one that could be a satellite when I checked) and some other plane trails.

I also combined the sequence into a video clip (HD 1080p) with two parts : first a natural view (stary sky rotating) and second a trailing view (star trails drawing). It could be donwloaded directly here :

IC 1396 – Sunglasses Optional

A region of emission nebulosity in the constellation of Cepheus, about 3,000 light years distant, it is hundreds of light years across with an apparent width of about ten full moons. The Elephant Trunk Nebula can be seen at 9 o’clock, which is a mix of gas and dust and a star forming region.

This was taken from the David Le Conte Astronomical Observatory in Guernsey where we are very fortunate to have Bortle 2/3 skies. It was taken between August and October on six separate nights, setting up and packing away the equipment each night.

The equipment used was a Starlight Xpress Trius 814 mono CCD with Astrodon narrowband filters (3nm for OIII and SII and 5nm for Ha), a Takahasi FS60 doublet with reducer to give a 255mm focal length, all sitting on an iOptron GEM45 equatorial mount.

It comprises 20 minute exposures as follows: 20 x Ha, 30 x OIII and 23 x SII, totalling about 24 hours integrated imaging time. They were calibrated and processed with Pixinsight and mapped to the Canada France Hawaii Telescope (CFHT) palette where Ha, OIII, SII are mapped to R, G, B channel respectively.
