IC 2948, also known as the “Running Chicken Nebula”, is usually described as “almost featureless emission nebula”.
True as it may be in RGB images, this emission nebula is very rich in details and with a remarkable 3D appearance in narrowband images.
The difficulty to see the "chicken" does nor diminish the beauty of it.
Taken with a CDK 20" f/6.8, STX 16803, Exposure time: 12.5 hours (Ha: 5.5 hours; OIII: 5.5 hours; RGB 1.5 hours -only for the stars).
