Hi all,
An image of the globular cluster Messier 71 has been uploaded. This cluster has been discussed as open or globular since it was classified as a cluster. After several switches, finally in the 1970’s it was classified as globular based upon photometry and the presence of a horizontal branch in the H-R diagram, typical of globulars. The image as well as some more info can be found at:

Hi all,
An image of Messier 105 has been uploaded. M105 harbors a massive black hole (140-200 million solar masses) and it is considered an AGN (Active Galactic Nucleus). You can find its image as well as more info at:

Hi all,
Now, another Messier and another elliptical galaxy, Messier 49. This galaxy is larger than any galaxy in the Local Group and it is the largest in the Virgo Cluster. You can find the image as well as some more info at::

Hi all,
This time, a small compact elliptical galaxy has been uploaded. Messier 32 is a satellite of our neighbor, M31, and has a large number of helium-burning stars close to its center. The image as well as some more info can be found at:

Hi all,
This time, another open cluster belonging to the Messier catalog has been uploaded. Messier 38 is located in Auriga and is experiencing a fly-by by another, close, open cluster, NGC 1907. The image and some more info can be found at:

Hi all,
Still another open cluster belonging to the Messier Catalog. Messier 39 is a small open cluster with 30-50 stars. But five of its stars are “peculiar”. This is the adjective used to describe stars that show unusual metallicities. The image and some more info can be found at:

Hi all,
An image of Messier 34, an open cluster, has been uploaded. This cluster is associated to several other open clusters (like M45 and others), sharing distance and motion type. The image and some more info can be found at:

Hi all,
Another Messier open cluster (M37) has been uploaded. This is a rather old cluster with over a dozen red giants. You can find the image and some more info at:

Hi all,
Continuing with the high resolution Messier Catalog, an image of Messier 29, an open cluster, has been uploaded. M29 belongs to the Cygnus OB1 association and therefore a significant part of its 50 stars belong to hot, bright, bluish, spectral class B0. You can find the image and some more info at:

Hi all,
I know that Messier 31 is a classic image. Probably, together with M42, one of the most imaged deep sky objects. This image has been the result of combining images from three telescopes, a 106 mm and a 150 mm refractors as well as a 24 inch reflector. The goal was to have a high resolution image of M31. You can find it at:
