Target: M16 Eagle Nebula NGC6611
Camera: Canon 350d modified,
Exposure Capture: DLSR Focus
Scope: GSO 8” RC
Mount: EQ6 Pro
Exposure Setting: Prime focus, ISO800 ICNR off Daylight WB
Exposure: 9 x 8.5 minutes taken 29/05/09 between 9:00 and 11:45pm
Seeing: Poor, fair amount LP, moon setting, windy,
Guiding: Orion Starshoot Autoguider using PHD
Focus: DSLR Focus
Stacking: DSS, 5 darks, 5 flats
Processing: PS7, CS3
Info: Situated in the Serpens
Type Emission Right ascension 18h 18m 48s Declination -13° 49’ Distance 7,000 ly (http://en.wikipedia.org/wiki/Light-year) Apparent magnitude (V) +6.0[1] (http://en.wikipedia.org/wiki/Eagle_Nebula#cite_note-simbad-0) Apparent dimensions (V) 7.0arcmins
Radius 70×55 ly (cluster 15 ly) Absolute magnitude (V) -8.21 Notable features 5.5 million years old
The Eagle Nebula is both an open star cluster and a large bright area of emission nebulosity. It is located in the south east corner of Serpens Cauda, close to the Scutum boundary. Within M16 are several complex star forming regions, the most noteworthy of which is variously referred to as the "Star Queen and her Throne" or the "Towering Pillars" (made famous by the HST image) and often referred to as the Pillars of Creation. Towards the centre in this photograph, it is a giant structure more than 6 light years from end to end. Another giant star forming region is the "elephant trunk" structure to the north east. M16 is about 7,000 light years distant and was probably first observed by the Swiss astronomer P.L. de Cheseaux in 1746. It was catalogued by Charles Messier in June 1764, who was also the first person to note the nebulosity surrounding the star cluster.
