Hi all,
An image of NGC 7023, the Iris Nebula, has been uploaded. This is a broadband LRGB image (actually, some frames through an Halpha filter were also taken, but not used for the final image, because they did not seem to add anything).
This is a beautiful nebula, but also a very interesting object. You can find the image and additional information at:
Enjoy,
Josep
Que bonica i quin color blau més bonic, em recorda una pedra de quars
Interesant image amb Molta intensitat i claredat
