Hi all,
Today, we enjoy another open cluster belonging to the Messier Catalog, M25. It is rather old (90 million years old) and it is large (over 600 stars). You can see the image, as well as some more information at:

An image of another Messier open cluster, M21, has been uploaded
Hi all,
An image of another open cluster, Messier 21, has been uploaded. This is a very young cluster (less than 5 million years old) and its stars seem to belong to the Sagittarius OB1 Association. You can find the image and some more information at:

An image of Messier 56, a Northern Globular Cluster, has been uploaded
Hi all,
Another globular from the Messier catalog, M56, has been uploaded. This time, a cluster presenting two oddities: retrograde movement as it orbits the Milky Way, as well as its theorized origin, being the remainder of an “absorbed” (by the Milky Way) small galaxy that once was captured by the gravitational pull of our galaxy. You can find the image as well as some more information at:

An image of the open cluster Messier 18 has been uploaded
Hi all,
An image of Messier 18, an open cluster, has been uploaded. This is a very young but small cluster. Most of its 40-50 stars belong to the spectral classes B and A. You can find the image as well as some more information at:

An image of Ou4, the Giant Squid Nebula, has been uploaded
Hi all,
An image of the Squid Nebula has been uploaded. This is a very special nebula. Because of its faintness, and despite its large size, it was not discovered until June 2011 by amateur astronomer Nicolas Outters. The image shows the central region and needed more than 40 hours to show the best part of it. You can see the image and find some more information at:

A mosaic of the Pelican Nebula has been uploaded
Hi all,
A 3-pane mosaic of the Pelican Nebula has been uploaded. This image has been taken with narrowband filters only (short RGB exposures were used to display the stars in their natural color). You can find it at:

A deep image of Messier 27 has been uploaded
Hi all,
An image of Messier 27 has been uploaded.This is a very deep (over 100 hours of exposure) image of this planetary nebula and is the result of a joint project with Don Goldman. It was taken with narrowband filters (Halpha, NII and OIII). The inclusion of the NII filter was due to the intensity of this emission in the nebula’s spectrum. You can find some more details and the image at:
Enjoy!
