- What am I looking at?
- The Heart Nebula is a large star-forming region whose glowing loops resemble a heart.
- How far away is it?
- About 7,500 light-years away.
- Where is it in the sky?
- In Cassiopeia, near the W-shaped constellation.
- Why does it matter?
- A rich narrowband object with bright H-alpha structure and embedded young star clusters.
- When is the best time to photograph it?
- Autumn nights when Cassiopeia is nearly overhead.

When to image this target
Nebula in Cassiopeia; best planned for September through November from New Jersey.
Autumn is a strong window for Cepheus, Cassiopeia, Andromeda, and late Cygnus fields.
Assumes a New Jersey backyard horizon and evening imaging.
Emission nebulae are good candidates for narrowband filters; reflection nebulae prefer darker skies.
IC 1805 is listed here in Cassiopeia.
Current frame: Narrowband / Ha, OIII, SII.
