If you look to the edge of the central empty space of this
wonderful nebula, you can see dark trunks of dense interstellar
matter. These trunks are created by strong stellar winds of the young,
bright stars in the nebula center. Each trunk originates in gaseous
globule, which can shrink enough over time and create a new star. Or
the stellar winds from already born stars win and the globule is
dispersed before its gravity is able to keep the gas together.
Thomas Lelu used his G2-4000 camera on 10” corrected Newtonian
telescope to acquire this image. Exposures were taken through
photographic red, green and blue filters as well as through
narrow-band Hα, OIII and SII filters and
combined together. Total exposure time exceeds 21 hours.
