The Iris Nebula is a reflection nebula located in the constellation Cepheus near the star Polaris in our northern sky. It is approximately 6 light years across and about 1300 light years from earth.

The nebula's blue color is caused by the scattering of light from the central star , HD 200775, by the dust grains within the nebula.

Unveiling the haunting beauty of the Dark Wolf Nebula (LDN 1235), a captivating region where dark interstellar dust contrasts against a backdrop of glowing hydrogen and scattered starlight. Resembling the silhouette of a wolf, this cosmic formation lies hidden in the constellation Cepheus.

🔭 Target: LDN 1235 (Dark Wolf Nebula)

📍 Location: Constellation Cepheus, approximately 1,000 light-years away

🌟 Apparent Magnitude: Diffuse and faint

📐 Apparent Size: ~1 degree

About the Region:

The nebula’s dark shape is a result of dense molecular clouds that obscure the light of background stars. Embedded within are faint reflection nebulae, glowing faintly from nearby starlight. This region is an active site for star formation, making it a treasure trove for astrophotographers and astronomers alike.

The Iris nebula (NGC 7023) is a reflection nebula in the constellation Cepheus. Reflection nebula means that there are common clouds of interstellar dust that reflect the light of a nearby star. In this case, it's a very young star SAO 19158, which is only about 5000 years old. Iris nebula was discovered by William Herschel in 1794. It's approximately 1400 light years away and it has 3 light years in diameter.
