TARGET: NGC 1763 Bennet 27
Scope: GSO 8” RC
Mount: EQ6
GS: Stellarvue 80ED
GC: Orion SSAG
Main Camera: Modified Canon 350d
Filter: Astronomik LP clip filter
Camera Setting: ISO800 CWB RAW
Exposures: 15 x 8 minutes 2hrs total (5darks, 5 flats applied) 22/11/2009
Focus: and Capture: DSLR Focus
Guiding: PHD
Processing: CS3
Location:
Right Ascension: 4 : 56.8 (hours : minutes)
Declination: -66 : 24 (degrees : minutes)
Apparent Magnitude:
Apparent Diameter: 25. (arc minutes)
Details:
A cocoon shaped wreath like nebula that consists of many different components. At the centre lies a cavity with a bright blue star cluster, which gives it an appearance similar to that of N44. A trio of oval shaped patches lie at the top with two containing embedded star clusters. All the separate parts combine to form a magnificent spectacle that is best appreciated in very long exposure astrophotography.
NGC 1763 is the designation for one of the three patches with the entire complex being referred to as N11 with one of the northern extensions being catalogued as N11B. The whole entire complex is the second largest HII region in the LMC but is snubbed in favour of the Tarantula Nebula.
The 1000 light year wide cloud is centered around the star cluster NGC 1760. At the heart of this cluster is an OB association called LH9. Research has determined the age of LH9 to be approximately 3.5 million years old, this means that the N11 complex is much older than the Tarantula Nebula.
Investigations have revealed the more evolved nature of N11, it is likely that a 2nd generation of star formation is taking place. Evidence of this is a lack of infrared sources, a greater abundance of these is found in less evolved nebulae. Further adding to this is that many of the infrared sources in N11 share the characteristics of young stellar objects and protostars.
