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.

The mythical Plane Engine Nebula #astrophotography

CosmoSidewalk, 9 months ago to Astro Spanish

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).

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.

What is the shape of lightning? Not as we usually see it, in all its jagged forking beauty, but in cross-section. Are those formations cylindrical? Hexagonal? I'd love to hear your thoughts.

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.

Sunny from the balcony… 😊

Globular clusters have their charm. They are dense balls of very old stars with a scent of unsolved misteries: are they ancient cores of dwarf galaxies that merged with our own galaxy billions of years ago, or are they primordial star clusters that formed without not much gravitational interaction, keeping them tight?
This is M5, located in the path to Serpens. Packed with cluster variables we could establish its distance: about 25 k l-y from our Sun.

Responsible of this wreck is a dying star known as Wolf-Rayet 7, rich in nitrogen. The bubble at the center was once part of this star. This bubble plus the twisted nebula that surrounds it, is what we call Thor’s Helmet.

Just went for it and I got it. A totally broadband picture of the Lagoon and Trifid nebulae from the balcony in Mexico City! Only 1 hr and 54 minutes. I’m still mesmerized with the result.
