Flaming star nebula
Officially known as IC405, the Flaming Star Nebula likes about 1500 light years and spans approximately 5 light years. The purple region's color is a mixture of red and blue light emitted by the star AE Aurigae but reflected to us by surrounding dust. The two regions are referred to as emission nebula and reflection nebula, respectively.
Tadpoles of IC 410
IC 410 is a faint and dusty emission nebula of more than 100 light-years across approximately 12,000 light-years away from Earth. The two tadpole like structures consist denser gas and dust and are approximately 10 light years long and are sites of ongoing star formation.
Spider and Fly nebulae
The spider-shaped gas cloud is an emission nebula labeled IC 417, while the smaller fly-shaped cloud on the right is referred to as NGC 1931 and is both an emission nebula and a reflection nebula.

Finally processed from last week, a two hour imaging attempt on NGC7000 & IC 5067/5070 — the North America and Pelican Nebulae in Cygnus. I always thought the dark nebula LDN 935 between them looked like a stylized saguaro & then the pelican more like a perched pterodactyl. But whatever.

This was my first fairly deep imaging attempt in a super rich star field with copious nebulosity. And it introduced me to walking noise. I've got really good data in there overall, but I can't refine the fine details or zoom tighter because of it. Almost like the astro version of discovering you have termites. Apparently the only effective way to eliminate it is through dithering during image capture. That's not going to happen automatically on the SkyGuider Pro. I'd need to stop every 3-5 images and tweak declination by fussing screws under the quick release plate & then a (hopefully) very slight camera twitch each time. Yuck. I have hit a significant limit with that mount lol.
But something else interesting are some orange-ish streamers on the right half of the image (up top & then a couple more exiting lower right side of the Pelican). I'm trying to figure out if they're legitimately some sort of flux nebulosity, or another type of sad imaging artifact. Can't readily compare with other images since stars overpower those areas or contrast has been amped to essentially clip the darker background.
These nebulae lie in the constellation Cassiopeia at a distance of about 6000 light years from Earth. IC1805 is named for its resemblance to a human heart. IC1848 is sometimes also referred to as the Embryo Nebula.

The Sadr region has many emission nebulae. The butterfly nebula (upper left) and the crescent nebula (lower right) are the most prominent here, but many filamentary regions in between are captured and are more apparent here in the Halpha image than in the color image.
Taken as a 4-panel mosaic and processed in pixinsight. The focus shifted throughout the night since the temp dropped faster than expected. As a result, the right panels appear sharper than the left.

This composition in stardust covers over 8 degrees on the northern sky. The mosaicked field of view is west of the familiar Pleiades star cluster, toward the zodiacal constellation Aries and the plane of our Milky Way Galaxy. At right in the deep skyscape is bluish Epsilon Arietis, a star visible to the naked-eye and about 330 light-years away. Reflecting starlight in the region, dusty nebulae LBN762, LBN753, and LBN743 sprawl left to right across the field, but are likely some 1,000 light-years away. At that estimated distance, the cosmic canvas is over 140 light-years across. Near the edge of a large molecular cloud, their dark interiors can hide newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to self-gravity, the protostars form around dense cores embedded in the molecular cloud. via NASA ift.tt/2A1Zfx4
No galaxies or nebulae to see here. This is just an open cluster of stars, happily named M29 and sitting up there in the constellation of Cygnus.
This open cluster consists of thirty stars, the brightest of which form a "stubby dipper", giving the cluster a boxy appearance. It is about 6,000 light years away and is only 11 light years across but the five brightest stars are all giants giving the cluster the luminosity of 160,000 times that of our sun.
Watch out. This cluster is approaching us at 28 km/sec. You'd better duck when it gets here. Wear sunglasses and a high factor sunblock.

We are in the constellation of Auriga, specifically in the HII region Sh2-230. This is a large emission nebula that extends for at least 5° in a region already rich in nebulae. The Sh2-230 region is located at a distance of about 10430 light years from us and is part of the Perseus Arm of our galaxy.
In the same image, but on different planes, other fascinating nebulae are visible:
On the right, IC405 (Sh2-229): Known as the Flaming Star Nebula, IC405 is an emission and reflection nebula located 1630 light years from us. It is illuminated by the irregular variable star AE Aurigae.
In the center, IC410 (Sh2-236): Sometimes called the Tadpole Nebula, IC410 is a large emission nebula. It is associated with the open cluster NGC 1893, formed by massive young stars. It is located about 19,640 light years from us. IC410 is nicknamed the Tadpole Nebula because it hosts dark dust clouds shaped like tadpoles that seem to swim toward the nebula's center. These “tadpoles” of IC410 are gas globules, small dense nodes of dust and gas that give birth to young stars.
On the left, IC417 (Sh2-234): Often called the Spider Nebula, IC417 is a large emission nebula visible in Auriga. It is linked to the open cluster Stock 8 and is the site of important star formation processes. It is located about 7100 light years from us.
As for the technical details, this image was acquired with a Tecnosky AG70 telescope, a ZWO ASI2600MM PRO imaging camera, a ZWO ASI174MM Mini guide camera on OAG-L, and an EQ8-R PRO mount. The controller used is AsiAir Plus. 98 subs of 600" were acquired in narrowband with 3nm Antlia filters and 118 of 120" in broadband. Due to weather and light pollution, only 54 shots (18 per filter) were integrated into the narrowband for 9 hours.

N: Too many stars, too many trails! While it's easy to travel by plane with this mount, the tracking performance isn't up to the task. It needs autoguiding for scales below 15 arcseconds/px.
This time I didn't took neither flats nor darks. I ended up syntetizing a master flat from the lights after some blurring. I think It worked.
The Bug Nebula, NGC 6302, is one of the brightest and most extreme planetary nebulae known. The fiery, dying star at its center is shrouded by a blanket of icy hailstones. This NASA Hubble Wide Field Plantery Camera 2 image shows impressive walls of compressed gas, laced with trailing strands and bubbling outflows.
hubblesite.org/newscenter/archive/releases/nebula/2004/46...
The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects. Though its wingspan covers over 3 light-years, NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the dying central star of this particular planetary nebula has become exceptionally hot, shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This sharp and colorful close-up of the dying star's nebula was recorded in 2009 by the Hubble Space Telescope's Wide Field Camera 3, installed during the final shuttle servicing mission. Cutting across a bright cavity of ionized gas, the dust torus surrounding the central star is near the center of this view, almost edge-on to the line-of-sight. Molecular hydrogen has been detected in the hot star's dusty cosmic shroud. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius).

Tracking was very good. I had very low periodic error, especially in DEC. DEC error has been a bit of an issue in the past. I processed the stacked TIFF in Gimp. I only adjusted levels. I pulled out the red channel and added it as another luminosity layer to increase the red in the picture.

The dusty region between Ophiuchus and Scorpius contains some of the most colourful and spectacular nebulae ever photographed. The upper part of the picture is filled with the bluish glow of light from hot stars reflected by a huge, cool cloud of dust and gas where such stars are born. This dust is also seen as a dark nebula, a molecular cloud, hiding the light of background stars, especially on middle left (east) of the picture.
Dominating the lower half of this cosmic landscape is the over-exposed image of the red supergiant star Antares, a star that it is steadily shedding material from its distended surface as it nears the end of its life. These tiny, smoke-like solid particles reflect Antares' light and hide it in a nebula of its own making. Antares and its nebula are about 600 light years away. Partly surrounding Sigma Scorpii (735 light years distant) at the right of the picture is a red emission nebula, completing the most comprehensive collection of nebular types ever seen in one photograph. There's also two globular clusters, one of the nearest to the sun, M4 (NGC 6121, 4500 light years away) at lower centre right and NGC 6144, 28,000 light years away, buried behind Antares' haze
It's one of the most beautiful regions in the night sky and there are so many large h-alpha nebulae include The North America nebula and nebulae around Sard star. I took this pic in summer under the darkest sky in Czechia, in Šumava National Park in Bortle class 3.

North American and Pelican nebulae, taken with SBIG ST-8300M monochrome CCD camera through Orion 80ED telescope with Televue 0.8x field flattener / focal reducer (FL=480mm, F/6).

NGC 3132 is a striking example of a planetary nebula. This expanding cloud of gas, surrounding a dying star, is known to amateur astronomers in the southern hemisphere as the "Eight-Burst" or the "Southern Ring" Nebula.
The name "planetary nebula" refers only to the round shape that many of these objects show when examined through a small visual telescope. In reality, these nebulae have little or nothing to do with planets, but are instead huge shells of gas ejected by stars as they near the ends of their lifetimes. NGC 3132 is nearly half a light year in diameter, and at a distance of about 2000 light years is one of the nearer known planetary nebulae. The gases are expanding away from the central star at a speed of 9 miles per second.
This image, captured by NASA's Hubble Space Telescope, clearly shows two stars near the center of the nebula, a bright white one, and an adjacent, fainter companion to its upper right. (A third, unrelated star lies near the edge of the nebula.) The faint partner is actually the star that has ejected the nebula. This star is now smaller than our own Sun, but extremely hot. The flood of ultraviolet radiation from its surface makes the surrounding gases glow through fluorescence. The brighter star is in an earlier stage of stellar evolution, but in the future it will probably eject its own planetary nebula.
In the Heritage Team's rendition of the Hubble image, the colors were chosen to represent the temperature of the gases. Blue represents the hottest gas, which is confined to the inner region of the nebula. Red represents the coolest gas, at the outer edge. The Hubble image also reveals a host of filaments, including one long one that resembles a waistband, made out of dust particles which have condensed out of the expanding gases. The dust particles are rich in elements such as carbon. Eons from now, these particles may be incorporated into new stars and planets when they form from interstellar gas and dust. Our own Sun may eject a similar planetary nebula some 6 billion years from now.

Edited Spitzer Space Telescope image of the region around Rho Ophiuchi, showing lots of nebulae and stars. Color/processing variant.
Original caption: Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud from NASA's Spitzer Space Telescope. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions to our own solar system. Located near the constellations Scorpius and Ophiuchus, the nebula is about 407 light years away from Earth.
Rho Oph is a complex made up of a large main cloud of molecular hydrogen, a key molecule allowing new stars to form from cold cosmic gas, with two long streamers trailing off in different directions. Recent studies using the latest X-ray and infrared observations reveal more than 300 young stellar objects within the large central cloud. Their median age is only 300,000 years, very young compared to some of the universe's oldest stars, which are more than 12 billion years old.
This false-color image of Rho Oph's main cloud, Lynds 1688, was created with data from Spitzer's infrared array camera, which has the highest spatial resolution of Spitzer's three imaging instruments, and its multiband imaging photometer, best for detecting cooler
materials. Blue represents 3.6-micron light; green shows light of 8 microns; and red is 24-micron light. The multiple wavelengths reveal different aspects of the dust surrounding and between the embedded stars, yielding information about the stars and their birthplace.
The colors in this image reflect the relative temperatures and evolutionary states of the various stars. The youngest stars are surrounded by dusty disks of gas from which they, and their potential planetary systems, are forming. These young disk systems show up as red in this image. Some of these young stellar objects are surrounded by their own compact nebulae. More evolved stars, which have shed their natal material, are blue.

Three versions of Heart and Soul nebulae and double cluster in Perseus. With integration time of 10 hours and 16 minutes its my biggest project yet. I planned to shoot more, probably for as long as 30 hours, but after a few nights i decided to process it. First I wanted to process it really precisely, but then i somehow changed my mind and went for pretty simple and basic way. I just stretched it, did some selective tweaks and that was pretty much it. Lastly i changed brightness, contrast and color balance a little bit, and got this three versions. I will most likely process this data again and see what i can get with a little more time spend playing with the image, bot for now i am done with it. It was shot over 5 nights from bortle 5 and 4, with Nikon D3500 IR modified and 70-300mm f4.5-6.3 AF-P DX VR ED kit lens, tracked with unguided Star Adventurer 2i on Velbon Sherpa 200D tripod. Exposure times were 90-180 seconds long at different ISO settings (from 400-3200. All stacked in DSS and processed in Photoshop with help of Starnet V2. I am pretty happy with the final images, although i might try to reprocess it in the future to see if i can make it look any better. If any of you would like to process it, i would gladly let you all the data or just a stacked image, just email me at astrowave000@gmail.com. I would love to see what others can get. I wish you all Clear skies for big projects like this one definitely was for me.
