This image was taken at our site in Sonsbeck/Germany beginning of November 2020. To me it shows impressive results taking into account light-pollution, half-moon and <3hrs of exposure time.
IC1396 is a concentration of interstellar gas and dust located in the constellation Cepheus, about 2,400 light years away from Earth.
Exposure times: RGB 12x1min each, L 20x1min, Ha 34x2min, O3 13x2min, S2 10x2min, total 2hrs 50min
Kit: Takahashi FSQ106, ZWO ASI6200, 10Micron GM1000
This is a crop of IC 1396 showing the Elephants Trunk Nebula.
The piece of the nebula shown here is a crop and 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. It is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396.
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. 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.(from: Wikipedia)
