Hi all,
NGC 5128 is a galaxy full with surprising features. This deep image highlights the very faint Hydrogen jet expelled from it due to one of the galaxy’s gravitational encounters. There are two previous versions of this galaxy in the web site, but this one is, by far, the deepest, with over 81 hours of exposure. Please see the image and its explanation at:

Hi all,
Sh2-239 is a very active star-forming place. It is an object where many Herbig-Haro objects can be found and, in infra-red images, it shows many Young Stellar Objects (YSOs). You can find a more detailed explanation and the image at the link below. This image belongs to the recently compilated collection of the 87 scientifically interesting objects posted recently.
Enjoy!

Hi all,
A 2×2 mosaic of the large supernova remnant CTB-1 has been uploaded. This SNR has e very curious pulsar. For decades, there was no detection of it. About seven years ago (2018), a pulsar was proposed as the remains of the star that exploded to originate CTB-1 and one year later, that pulsar was confirmed. The pulsar is one of the so called “cannonball” pulsars, showing a tremendous speed. Details about it and the final mosaic can be found in the link below. This image belongs to the recently compilated collection of the 87 scientifically interesting objects posted recently.

Hi all,
I know that it has been a very long time since my latest post. I have been extremely busy with a personal project that is not yet finished, but the hardest part is over.
This time, I have uploaded a page that collects what I consider the 87 most scientifically interesting targets in the night sky, at least according to my criteria. All of them have special scientific content and I encourage you all to visit their corresponding pages and read the reason why these objects have been imaged. You can visit this new page in the Astrogallery at:

Hi all,
NGC 1555 is a peculiar nebula in the constellation Taurus. It consists of emission nebulae, reflection nebulae as well as a beautiful surrounding of dust and IFNs. This star (T Tauri) as well as its surrounding nebulae have been thoroughly studied. mRecently, a protostar (star in the process of being formed) was found very close to T Tauri.

Hi all,
A higher resolution image of M16 has been uploaded. This image, another result of the fruitful joint project between Christian Sasse and myself, was taken nearly two years ago, but kept in the fridge until we had time. You can see it at:

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:

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:

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:

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:
