An image of the Bubble Nebula, NGC 7635, has been uploaded

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 of the massive O6.5 star (whose bowshock creates the bubble when interacting with the surrounding nebula), producing a clear 3D effect. This effect is more pronounced when color mapping the frames to a modified Hubble palette. You can find this image, in both color palettes (Hubble and natural) as well as more info at:

An image of NGC 2997, a barred spiral galaxy, has been uploaded

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 well as more information at:

An image of NGC 7331 has been uploaded

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, have originated from an unstable state. You can find the image and more information at:

An image of NGC 5985 and its companions has been uploaded

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:

NGC 5985, NGC 5982 and NGC 5981

An image of Arp 273, the Flower galaxies, has been uploaded

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:

An image of M8, the Lagoon Nebula, has been uploaded

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. You can find this image at:

A reprocessed image of IC 410, the Tadpoles, has been uploaded

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 dĀ”find this new version (that has replaced the previous one) at:

IC 410, the Tadpoles Nebula

Enjoy,
Josep
