The Elephant's Trunk Nebula (IC 1396A) is a bright section of the emission nebula and young star cluster IC 1396 in the constellation Cepheus.

Some characteristics:
Distance from Earth: 2,400 light-years.
The nebula is a globule—a dense concentration of interstellar gas and dust.
In images, the nebula exhibits a bright rim. This is the surface of the dense cloud, illuminated and ionized by the very bright, massive star HD 206267, located to the east of IC 1396A.
The nebula is an active star-forming region containing many young stars and protostars.

The size of the "Elephant's Trunk" itself is about 20 light-years in length.

Looks good, but it seems the full resolution wasn't applied. Can't see the details :(

That's all that fit in the frame :))
The integration time is short, so the image is a bit noisy. I want to try again in the summer, but only by shooting a panorama of the object)

Resolution: 1280x761 px, this is definitely not the full frame, meaning the resolution has been cropped.

The frame is slightly cropped only at the edges. Artifacts from stacking were present.

No, I lied. Looking at the resolution in other photos, I really did crop it—something quite heavily.

I'll check the source files, I don't think I deleted them.
