Taking such detailed image was definitely not easy, it required
almost 111 hours of exposure time to acquire both narrow-band and RGB
images to be able to compose false color image, showing incredible
details in nebula structure, as well as natural-color image showing
like the nebula complex could look to humans, providing our eyes are
way more sensitive.
The image was acquired with G4-16000 camera on CDK20 telescope
(0.5m modified Dall-Kirkham).
