TypeNebula ConstellationSerpens SeasonSummer PaletteNarrowband Integration time3h 40m Captured2020

A classic nebular field with star-forming structure and warm narrowband color throughout the frame.

What am I looking at?
The Eagle Nebula contains the Pillars of Creation — towering columns of gas and dust where stars are forming.
How far away is it?
About 7,000 light-years away.
Where is it in the sky?
In Serpens, near the rich star fields of the summer Milky Way.
Why does it matter?
Made famous by Hubble Space Telescope images of star birth in the pillars.
When is the best time to photograph it?
Summer when Serpens and the galactic core are well placed.

Best season June through August

Summer targets often improve later at night as the Milky Way climbs higher.

Good from NJ Late spring through early autumn

Assumes a New Jersey backyard horizon and evening imaging.

Object type Nebula

Emission nebulae are good candidates for narrowband filters; reflection nebulae prefer darker skies.
