Now it’s time to show y’all the complete photograph of the M16 nebula taken last week with my 80 mm refractor telescope. Could manage to get lots of details in a relatively short total exposure time of only 9 hours and 45 minutes.

Dust, ionized oxygen, sulfur and hydrogen, stars in the making, bok globules, protoplanetary disks, Herbig-Haro objects, immense light-year distances… Ladies and gentlemen: yes the Pillars of Creation @ M 16 taken with an 8 cm aperture refractor.

Globular clusters not only exist in galaxy’s halos. M71 is practically embedded in Milky Way’s disc, just halfway (apparently) in between Albireo and Altair. This globular cluster has another peculiarity: it is rich in metals which is unusual for an old object like this.

Had the chance to capture this galaxy, M51, from my obsevatory in Mexico City this very week! Zoomed in beforehand to show you the details of this magnificent pair of interacting galaxies.

M16’s region close to the galactic center. Famous for featuring the Pillars of Creation, M16, popularly known as the Eagle Nebula, here resembles the face of a bearded man (can you make it out?).
Took this picture from my rooftop in Mexico City.

This turned out to be the last picture with my 130 mm Newtonian telescope. Unfortunately, high winds knocked it out despite my ZWO Mount had more than 11 pounds of counterweights to hold it in place. Anyway, the fact that I was able to capture 3 galaxies that are about 35 M-ly away makes me love my hobby no matter what.

I published a few weeks ago a widefield view of the Omega Glob Cluster with my Rokinon 135 mm lens. Couldn’t resist to try a closer look with my 130 mm newt, so I shot it again! Wouldn’t you have done the same? Love this yaw dropping cluster!

There are better pictures of NGC4216, a Galaxy you can find in Virgo’s Constellation. My idea, however, to capture it was two-folded: to capture it “as it appears to be” from my rooftop in Mexico City, but mostly to capture and understand the supernova explosion that happened there a few weeks ago and that you can find (WOW!) in my photograph.

The steep learning curve to #astrophotography! Like most of us, I started out with a very modest rig and an unmodified DSLR camera. We have to add that my processing skills were also not the best. And although all this, I enjoyed the hobby as much as I am enjoying it now.

If I understood well, our cosmos at the beginning was a very dense but chaotic nebula. With inflation, it started to break into smaller clouds. Gravity pulled some of this gas and started to form stars. These stars, thanks to their energy, carved and shaped these nebulae.
Lower’s nebula, depicted in my attached picture, is a small remnant of this lengthy process.

It was the end of an astrophotography session, about 3:30 in the morning. I looked at Stellarium and found out that the huge globular cluster, the biggest we know of in this galaxy, with approximately 10 million stars, was out but low in my southern horizon. Decided then to take an hour and a half of one minute exposures just for fun, and this is the result: Omega Centauri from my rooftop!!!

Yesteryear did not take a picture of this big celestial rose. Yesterday I decided to give it a shot with my Rokinon 135 mm lens to capture it wide field. Though I used a OSC camera, I could through process create a Hubble-ish pallette. The central cluster of huge and very hot stars is catalogued as NGC2244.

This weekend I was able to escape to a dark site after a long time. The destination was a hidden getaway in the state of Guanajuanto, Mexico. I was able to see, with my naked eye the Andromeda Galaxy and, of course, the Milky Way. So I decided to shoot NGC1999. An object that is impossible for me to capture in my city’s observatory.
Only had the opportunity to capture a couple of hours, due to the unstable weather.

The idea is to present in a kind of unusual way an usual target, such as the well known Soul Nebula (SH2-199). This picture tries to achieve that.

First light of my brand new camera ASI533MC-PRO. My first cool camera! Took this from my rooftop in Mexico City.

Happy holidays, everybody! To celebrate, I share with you’ll my best picture ever of the Pacman Nebula (NGC 281)!

Couldn’t resist the temptation to reprocess my Trifid nebula (Messier catalogue number 20). Taken from the bottom of the profound light pollution sea of Mexico City last June.

I did not know that it is very probable that M74 galaxy hosts in its core not a supermasive but an intermediate size black hole of about 10000 solar masses. Though, this has not been confirmed yet. If indeed this is the case, then it will be the first intermediate black hole we have observed.
This was taken from my roof, in Mexico City. It is amazing that we're able to capture a distant object with off the shelf astronomy gear.

Lame picture, right?

Guess how many galaxies are in it...

On June, during my birthday (or should I say birth-night?), I took the data to get this picture of the globular cluster M5. Although it was a few months ago, I did not have some "tools" in my Pixinsight arsenal, neither the bit of extra processing knowledge I have now (in this hobby you're continously learning something new). So, this is my today's version of that "old" picture. I do not want you to see the previous version -is kind of embarrasing.

Just enjoy this open star cluster at the center of the Heart Nebula, Melotte 15. Here you can find my favorite kind of stars: massive blue O and B type, according to Annie Jump Canon’s stellar classification. Surrounding this cluster is a good quantity of ionized hydrogen and oxygen. The false color technique I used is known as HOO, that I paired with “normal” RGB stars.
Took this from my roof (not the balcony anymore) in Mexico City.

Pushing the limits of what’s feasible with my rig and from my light polluted site. This is my take in RGB (no narrowband data at all) and with a “modest” light pollution filter (Baader Moon & Skyglow Filter) of the Cocoon Nebula.
Ionized hydrogen, reflecting nebula, dust and multicolored stars, all together for our own pleasure. Technology and a little bit of craft allow us to see this fantastic corner of our own galaxy.

Dark nebulae rule! This beauty can be found in the constellation of the scorpion. The amount of stars is staggering, they look, literally, like sand. Catalogued by Barnard with the number 252, it’s commonly called the dolphin nebula (kind of nosy, that dolphin though).
Processed by me with data of Telescope Live.

Now is time for the spectrum of a Wolf-Rayet type of star: WR-7 also catalogued as V1687 Cyg.
It is a WC, meaning that it is a star rich in carbon. We can actually "see" the carbon and helium inner layers, because the intense stellar winds and a pronounced unstable hydrostatic equilibrium have expelled its outer hydrogen layers to interstellar space. The broad emission lines are trademark of these types of stars.

I took this picture three years ago. On that time I used my Canon 1100D paired with my ES 80ED triplet refractor and the Optolong l-eNhance filter.
I am amazed about the star that produces this huge nebula at the center of the photo. This is a Wolf-Rayet type of star. I’m looking forward that at the first chance the weather lets me, take some spectra of it so that I can illustrate further to you how weird this star is.
