Hi all,
An image of NGC 6164-5 and the Blue Doily Nebula that surrounds them has been uploaded. This nebular complex is very interesting in that the central spectroscopic binary star has ejected material in two phases. The first one, rich in Oxygen, conformed the bluish nebula that, in absence of a popular name I have called it the “Blue Doily Nebula”. The red emission nebulas in its center are NGC 6164 and 6165.You can find the image and more information at:
Enjoy,
