Hot young stars abound in this region on the boundary between the constellations Cassiopeia and Cepheus. The Bubble emission nebula in the center is formed by the solar wind emanating from one such star, pushing against a cloud of ionized hydrogen which glows a characteristic red. To the right, star formation region NGC 7538 also glows red. At the upper left, open cluster Messier 52 shines brightly.

Gyulbudaghian's Nebula(in left- bottom corner) is a little-known variable reflection nebula, similar to Hubble's variable nebula.
t the heart of the Herbig-Haro object lies the variable Herbig AbBe pre-main sequence star PV Cep. This is a newly formed star that is surrounded by a rotating disk of material. At right angles to this disk are two jets of material, streaming away from the star at high speeds. We see the effects of one of these jets on the north side of PV Cep as the stream of material meets the surrounding gas in the interstellar medium. The jet to the south is obscured by a dark nebula (producing an absorption of over 3 magnitudes) (text: www.skyhound.com/observing/archives/oct/GM_1-29.html )

NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years , similar to the distance of M101 (NGC 5457) in the constellation Ursa Major. Both were once considered to be part of the Local Group , but are now known to be among the dozen bright spiral galaxies near the Milky Way but beyond the confines of the Local Group. NGC 6946 lies within the Virgo Supercluster.
Discovered by William Herschel on 9 September 1798, this well-studied galaxy has a diameter of approximately 40,000 light-years, about one-third of the Milky Way's size, and it contains roughly half the number of stars as the Milky Way. It is heavily obscured by interstellar matter due to its location close to the galactic plane of the Milky Way. Due to its prodigious star formation it has been classified as an active starburst galaxy. (Courtesy Wikipedia)
An H II region or HII region is a region of interstellar atomic hydrogen that is ionized. It is typically a cloud in a molecular cloud of partially ionized gas in which star formation has recently taken place. These can be seen in distant spiral galaxies as red-pink star-like “knots” in the spiral arms, several of which are evident in this image.

It takes something special to get me out of bed handy during the festive season but not knowing how long the tractor would stay on this I decided to make the move.
Not one of my finest efforts with poor light and a complete balls up on my part getting the subject nicely in frame, but after some considerable processing and a bit of a crop I think i've got it to something good enough to share.

The Elephant's Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the east of IC 1396A. (In the Spitzer Space Telescope view shown, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk nebula. This pressure has triggered the current generation of protostars.

IC 1396 is a star-forming region of gas and dust in the constellation Cepheus. Spanning ~2.5 degrees in the sky, it appears to us almost 5x the diameter of the Moon. Its nebulosity can be faintly seen visually through a telescope under dark skies, but photographically, it is dramatic.
Due to the nebula's large size, this image is a 6-panel mosaic captured through both narrowband (SII, Ha, OIII) and color (R, G, B) filters over multiple nights in September and November of 2023. Most data was collected under dark skies near Goldendale, WA, with SII and some RGB data captured from Seattle, WA.

Sh2-174, also named Valentine's Rose, is a faint planetary nebula in Cepheus. The object was first noticed by Stewart Sharpless, who discovered the red nebula consisting of ionized hydrogen and the blue nebula of the double ionized oxygen (OIII). The ionized hydrogen and the ionized oxygen did not have the same center. The ionized oxygen is shifted west and the white dwarf (a stellar core remnant composed mostly of electron-degenerate matter) was discovered in the middle of the blue nebula (in the picture it can be seen as a small blue dot). In 2008 an Australian doctoral student discovered from the velocity of the nebula its age, i.e. the time at which it began to expand, did not coincide with the age of the white dwarf. The white dwarf was much too cool and thus too old - about a hundred times older than the nebula. The most plausible explanation for this is that a single white dwarf is just passing through the gas cloud and ionizing the gas surrounding it, so the nebula could not be caused by the mass loss of the dying star. Not all astronomers share this view and consider Sh2-174 a Planetary Nebula, namely PK 120+18.1. Also the astronomical database Simbad lists this object as PN.

Description:
This is a large and quite faint emission nebula and star forming region over 100 light-years across, located about 2,400 light-years away in the constellation Cepheus. It is energized by the bright, bluish central multiple star. The very small Elephant’s Trunk nebula (IC 1396A) is inside the dark elongated globule just to the right of centre.
From one web site: "The brightest star (38,000 times brighter than the Sun) ... [at the lower left edge of the nebula] is mu Cephei. It is a red supergiant star with a diameter larger than the orbit of Saturn, some 2536 times the diameter of the Sun. It is one of the largest stars we know of. Also called Herschel’s Garnet Star, mu Cephei is a variable star that varies in magnitude from 3.4 to 5.1 over a period of approximately 730 days."

Adrift in a cosmic sea of stars and glowing gas the delicate, floating apparition left of center in this widefield view is cataloged as NGC 7635, the Bubble Nebula. A mere 10 light-years wide, the tiny Bubble Nebula was blown by the winds of a massive star. It lies within a larger complex of interstellar gas and dust clouds found about 11,000 light-years distant, straddling the boundary between the parental constellations Cepheus and Cassiopeia. Included in the breathtaking vista is open star cluster M52 (lower left), some 5,000 light-years away. Above and right of the Bubble Nebula is an emission region identified as Sh2-157, also known as the Claw Nebula. Constructed from 47 hours of narrow-band and broad-band exposures, this image spans about 3 degrees on the sky. That corresponds to a width of 500 light-years at the estimated distance of the Bubble Nebula [text from APOD, 2017, oct 26]

Re-Process!
I re-visited my image of the Elephant's Trunk Nebula in Cepheus taken last year using the Esprit 100 and ASI294MC Pro.
A Duo-NB filter was used to collect dramatic Ha and OIII details with my color camera.
I didn't re-stack the data and start from scratch - just tweaked the final image. Lazy, right?
To achieve this image, I created a new luminance layer using a 80R/10G/10B channel mix.
This layer was stretched more aggressively than the underlying data using curves and Adobe Camera Raw.
I also pulled that blue channel WAY up to cool the image down.
The original image was VERY pink (as usual) do to setting the black point with globally stretched channels (with a DOMINANT H-Alpha signal in the red channel).
Time to step back and look at it... until I re-process it again. 😄
I promise to stop talking about the Elephant's Trunk Nebula for a while. 🐘

M31 aka The Andromeda Galaxy. Andromeda was the daughter of king Cepheus and his wife Cassiopeia. Cassiopeia would boast that Andromeda was more beautiful than the Nereids (the nymph daughters of the sea god Nereus). This angered Poseidon. Poseidon then send the sea monster Cetus to ravage Andromeda as divine punishment. King Cepheus then chains Andromeda to a rock as sacrifice to sate the sea monster. Along comes Perseus to save Andromeda and slay the sea monster. Ahhh so romantic.
