Hi all, A few weeks ago, I decided to retake an image of the Bubble Nebula (NGC 7635, the previous one had been taken in 2016). This time, I was able to take a deeper image, adding also SII as one of the narrowband filters employed. This nebula is very attractive because of the geometry …

Hi all, An image of NGC 2997, a spectacular barred spiral galaxy, has been uploaded. As recently as in August 2023, 48 new dwarf galaxies have been discovered to orbit NGC 2997. They show a distinct bluish color, meaning that most of them have high rates of star formation. You can find the image, as …

Hi all, An image of NGC 7331 has been uploaded. This galaxy, a frequent target for astrophotographers, has been often compared to the Milky Way. Nevertheless, this one has no central bar, it is a flocculent galaxy and has some star streams around it. The absence of a central bar has been attributed to, probably, …
Hi all, An image of NGC 5985, a beautiful spiral galaxy, and its companions (NGC 5982 and NGC 5981) has been uploaded. NGC 5985 has been extensively studied for its dark matter halo, by determining the stars’ rotation speed against its luminous mass. You can find the image, as well as some more information, at: …

Hi all, An image of NGC 2336, a spiral galaxy, has been uploaded. This galaxy has a remarkable star-forming activity and has been extensively studied. You can find the image and more info at: NGC 2336 Enjoy, Josep
Hi all, An image of a curious interacting pair of spiral galaxies, Arp 273, has been uploaded. This pair are very far away, over 300 million light years, and therefore very tiny in the image. Anyhow, this image shows still a great deal of detail. You can see the image and some additional informations at: …

Hi all, Messier 8 deserves many pictures and this is what you can find in my web site. This one is the sixth image that I have taken, this time in close collaboration with Christian Sasse. This image is a two-pane mosaic that provides an original resolution of 10800×12300 px. I recommend exploring the core. …

Hi all, IC 1396, also known as the Elephant Trunk Nebula, is one of the nebulas that show a great deal of detail. In this case, this is a reprocessed image, done to better show these details. You can find it at: IC 1396A. The Elephant Trunk Enjoy, Josep
Hi all, Recently, and taking advantage of the new processing tools currently available, I reprocessed this nebula. These new tools allow for an increased detail and the fine structure is better (and more reliably, seen. You can d¡find this new version (that has replaced the previous one) at: IC 410, the Tadpoles Nebula Enjoy, Josep
Hi all, An image of Mz 3, the Ant Nebula, has been uploaded. This planetary shows an intriguing structure that was studied, in 2018, by N. Clyne et al. This a very small and young planetary only visible from the Southern hemisphere. You can find the image at: Mz 3, the Ant Nebula Enjoy, Josep
