" IC 1396A is one of the most photographed objects in the Northern Hemisphere sky. Strangely the JPO team had never imaged it before. So, with a one hour window of clear sky over the Jodrell Plank Observatory, Kurt decided to point the Seestar S30 in its direction. The Seestar does well with large nebulae and for only one hour of exposures we thought this image, although 'crunchy', was not bad for a telescope having only 30mm of aperture.
We selected a colour palette in modified RGB, which follows the HOO narrow band palette in outline.
The above image captures IC 1396A, commonly known as the Elephant's Trunk Nebula, a dense globule of interstellar gas and dust embedded within the much larger ionized hydrogen region IC 1396, located in the high-northern constellation Cepheus approximately 2,400 light-years from Earth.
Astronomical Characteristics
Morphology & Dynamics: The dark, elongated structure—resembling an elephant's trunk—is a dense molecular pillar sculpted by the intense ultraviolet radiation and high-velocity stellar winds emanating from the massive, luminous central O-type star HD 206267 (located just off-frame). The bright rim seen edging the dark structure is an ionization front, where radiation from HD 206267 heats and ionizes the outer compressed gas shell.
Star Formation Site: The Elephant's Trunk is an active star-forming region (an H II region). The photoevaporative compression caused by nearby hot stars compresses the interior interstellar medium, triggering gravitational collapse and giving birth to young stellar objects (YSOs) and protostars hidden within the opaque dust lane.
Spectral Emission: Captured using a light-pollution (LP) filter, the false-colour/dual-band palette Highlights the ionized atomic hydrogen (Halpha) emissions in warm amber and orange tones, while contrasting background dust lanes and surrounding ionized gas appear in cooler dark hues.
