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 […]

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: IC 5070. The Pelican Nebula Enjoy, Josep

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 […]

Hi all, An image of Messier 10, a globular cluster very close to Messier 12, has been uploaded. This cluster is clearly more compact than M12 and is notable because it has a high number of blue stragglers in its core. You can find the image and some more information at: Messier 10. NGC 6254 […]

Hi all, An image of Messier 92, a globular cluster in the constellation Hercules, and pretty close to Messier 13, has been uploaded. This is one of the oldest and intrinsically brightest globulars in the Milky Way. You can find the image and more information at: Messier 92. NGC 6341 Enjoy, Josep

Hi all, Working in the preparation of the complete (still a year to go) Messier catalog taken with high resolution telescopes, I have reprocessed and uploaded two iconic galaxies: M51 and M83. The original images were taken with the 24″ and 20″ respectively. The new ones can be found at: Messier 51. NGC 5194 Messier […]

Hi all, An image of Messier 102, the Spindle Galaxy, has been uploaded. An important controversy was built around M102. Messier made a mistake in its description (it happened that no object was at the position he described) and several candidates came up. Finally, NGC 5866 was considered M102. You will find the image and […]

Hi all, An image of the open cluster Messier 11, the Wild Duck Cluster, has been uploaded. It is the most populated and the most distant open cluster of the Messier Catalog. You can find the image and some more information at: Messier 11. NGC 6705. The Wild Duck Cluster Enjoy, Josep

Hi all, An image of the globular cluster Messier 3 has been uploaded. This cluster has unusually high numbers of blue stragglers as well as of variable stars. Most notably, the number of variables of the RR Lyrae type is extraordinarily high (233). You can find the image as well as more info at: Messier […]

Hi all, Within the preparation of the full Messier Catalog in High Resolution, I have reprocessed two images that were taken some time ago. One is M74 and the second one is M17. You will find them at: Messier 74. NGC 628 and: Messier 17. The Omega Nebula More reprocessed images will keep on being […]
