Description

H-Alpha layer was made and published here https://astrob.in/353373/0/

For the final image, I wanted a much wider field and I used the Tamron 70-200 at 200mm, associated with the Canon 80D, for the color layer.

IC 2948/2944, two open clusters associated with an emission nebula, nicknamed "Running Chicken Nebula", has the particular characteristic of presenting Bok globules, small dark nebulae, discovered by David Thackeray, hence the name of Thackeray's globules.

NGC 3766 is a very dense open cluster that glitters like a pearl, hence its nickname "The Pearl Cluster". Cluster already photographed by myself and published here https://astrob.in/346625/B/
