Date & Site:

Imaged on 6/12/15;Palomar Mountain, CA

Conditions: significant winds; 70 degrees; transparent; above average seeing

Equipment:

Telescope: DSI 10" RC f/7.3 at 1867 mm fl

Mount: AP 1100 GOTO CP3
Camera: ST-10XME; CFW10; Hutech OAG-5 guider

Astrodon 3nm narrowband filters

Notes:

Exposures: 45 min (15 min subs) each of Ha, OIII and SII for total of 2.25 hours

The Eagle nebula is part of a region of strong hydrogen emissions and star formation. The single tower of gas (lower left) is 9.5 light ylears, or 90 trillion miles long. The pillars near the center of this image are famously known as the "Pillars of Creation". For for minformation, click here.

This image was obtained using narrow band filters to highlight the hydrogen (Ha), doubly ionized oxygen (OIII) and ionized sulfur (SII) emissions. The combined layers were color mapped using the Hubble palette which assigns green to Ha, red to SIII and blue to OIII.
