What’s more, the CielAustral group (J. C. Canonne, N. Outters, P.
Bernhard, D. Chaplain, L. Bourgon), as usual, acquired both
narrow-band images in Hα, OIII and SII
spectral lines as well as natural-color images using red, green and
blue color filters. Total exposure time of all frames needed to
compose these marvelous images is 253 hours.
Having all these images, it was possible to compose narrow-band
frames into false-color image, literally full of incredible details,
as well as to combine red, green and blue frames into true-color image
with noticeably less details, but showing us how this nebula could be
hypothetically perceived by humans.
The image was captured with G4-16000 camera on the 0.5 m CDK 20" telescope.
