Description

Taken from my rooftop. I found the Tak 1.6ext on the FSQ106 to have a bit of sag and had to throw away a lot of subs. I love this nebula and am working on a bi-colour version. Hoever I like the starless HA version here.

It was a real battle with the cloudy winter skies in Melbourne and work commitments trying to get all of the data.

The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years or about 90 trillion kilometers long.[4]

The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud to the north-west of the Pillars.[5] The brightest star (HD 168076) has an apparent magnitude of +8.24, easily visible with good binoculars. It is actually a binary star formed of an O3.5V star plus an O7.5V companion.[6] This star has a mass of roughly 80 solar masses, and a luminosity up to 1 million times that of the Sun. The cluster's age has been estimated to be 1–2 million years.[7]

The descriptive names reflect impressions of the shape of the central pillar rising from the southeast into the central luminous area
