Colliding Spiral Galaxies (NGC 520)

I was looking for a relatively small galaxy to capture with my planetary (2X Barlow) setup. Here we have 2 in 1. Skies became unsteady during this dark period, so that limited me to only 4 hours of L. But fortunately I was able to capture 6 hours of RGB.

"NGC 520 is a pair of colliding spiral galaxies about 105 million light-years away in the constellation Pisces. They were discovered by astronomer William Herschel on 13 December 1784.

Halton Arp called this the second-brightest very disturbed galaxy in the sky, and it is as bright in the infrared and radio bands as the Antennae Galaxies. Simulations indicate this object consists of two galactic disks that began interacting about 300 million years ago. The system is still in an early stage of its merger, showing two separate velocity systems in the spectra, and two small tails. Two galactic nuclei have been detected,and one is an H II nucleus.

The main galactic component is being viewed edge-on, making it fainter in the optical band. The secondary component is brighter but less massive than the main, and is located to the northwest. They are separated by a dark lane of dust. The region of the galaxies outside their nuclei experienced a period of increased star formation roughly around the time they began to interact."

For the first time, I captured an image of a galaxy outside of our own Milky Way galaxy. This was shot from a Balsam Knob in Blue Ridge Parkway, North Carolina.

This is a wide-field shot to capture the IC 342 through the delicate curtain of dust and star field of our own Milky Way. The galaxy's color are subdued a little because of what we look through to see it and I kept the dense stars and a hint of the dust to show why it is named the hidden Galaxy.

Located in the constellation Cassiopeia and discovered by William Herschel in 1787, the Bubble Nebula contains a massive 8.7 magnitude star and the stellar winds created the "bubble".

Processing this one was interesting. I tried many different variants of SHO workflows but nothing seemed to really fit the bill. I stumbled across the below Pixel Math combination and well, that was it.

Red - 60% SII + 40% Ha
Green - 60% Ha + 40% OIII
Blue - 70% OIII + 30% Ha

It gave me a very subtle picture that I really liked. Nothing seems to be blown out. I'll have to keep that for some future projects.

Einstein Cross, KG Observatory, Julian CA.

Here's my promised second attempt at trying to resolve Einstein's Cross. My first attempt was in 2018...

https://www.astrobin.com/367242/?nc=&nce=

Now I'm able to take advantage of my planetary setup with a 2X Televue barlow and the ASI6200 CMOS camera.

I estimated seeing at 4/5 while I captured 140 60s L subs. I then kept the best 90 with an average FWHM near 1.5".

The L subs were calibrated, aligned and average integrated in PI. I then applied HDR in PI to lower the core brightness followed by a mild MLT and a mild (100/8/5) USM in PS.

I'm happy to finally resolve the cross structure. My next attempt will use a similar setup and process, but with more subs during great seeing. "The Einstein Cross (Q2237+030 or QSO 2237+0305) is a gravitationally lensed quasar that sits directly behind the center of the galaxy ZW 2237+030, called Huchra's Lens. Four images of the same distant quasar (plus one in the centre, too dim to see) appear in the middle of the foreground galaxy due to strong gravitational lensing. This system was discovered by John Huchra and coworkers in 1985, although at the time they only detected that there was a quasar behind a galaxy based on differing redshifts and did not resolve the four separate images of the quasar.

While gravitationally lensed light sources are often shaped into an Einstein ring, due to the elongated shape of the lensing galaxy and the quasar being off-centre, the images form a peculiar cross-shape instead."

M78, Barnard´s Loop and LDN1622 in Orion

LDN 1622 is a dark nebula in Orion.
It is known as the Boogeyman Nebula due to both its shape and its dark color.
the obscuring dust of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away.
At that distance, this 1 degree wide field of view would span less than 10 light-years

The M78 nebula is a reflection nebula in the constellation of Orion, one of the brightest diffuse reflection nebula in the sky.
This nebulae belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth.

In between both targets is part of the Barnard´s Loop, which surrounds Orion´s Belt and the Orion Nebula (M42).

The technique I used was to bled starless version of an OSC RGB image and an OSC Duo-narrowband image.
These Two images combined formed the final RGB image which was then combined with the Luminance acquired with another setup.
Both setups were running in parallel and for this reason I was able to acquire 13h worth of data in one single night.

After this first night adventure in Piedras Rojas, I was able to return a few times and now I take my landscape astrophotography students to photograph this wonder of the Atacama.
This image was captured last week during my photo tour in Atacama. The conditions were difficult, largely due to the strong wind that took the thermal sensation to levels difficult to bear. Even so, my students and I managed to withstand the altitude and the cold and make incredible images of this wonder of the Atacama Desert.

The Sculptor Galaxy, NGC253

NGC 253, also named Sculptor Galaxy is one of the brightest spiral galaxies visible. This dusty galaxy lies 11 million light-years away.
About 70 thousand light-years across, NGC 253 is the largest member of the Sculptor Group of Galaxies.
The high dust content accompanies frantic star formation, earning NGC 253 the designation of a starburst galaxy.

This data was acquired by me in my hometown and processed by a friend and experienced Astrophotographer Maicon Germiniani who did a wonderfull job.

STORY:
The Monjes de La Pacaña are huge monoliths found in the Salar de Tara region of the Atacama Desert in Chile.
With varied formats and appearing completely out of nowhere in the middle of the desert, these monoliths stand out in the landscape and give an extraterrestrial air to the region's scenery.
Shooting at night at the Monjes de La Pacaña is a challenging and very fun task. Challenging because of the altitude above 4000 meters and the intense cold, which can easily reach -10 degrees Celsius even outside winter.

I have just returned from my second photo tour of the year in the Atacama Desert.
This image made in Piedras Rojas represents very well everything that Atacama means to me. Breathtaking landscapes and the best sky in the world for astrophotography.
Highlighted in the sky we have the Magellanic Clouds, the southern arm of the Milky Way and some of its main nebulae, the Andromeda galaxy, Zodiacal Light, an intense Air Glow, among others.
This is a panoramic shot made from 24 shots, 12 per line, with 15 seconds of exposure each. The quality you can get from single shots at Atacama is surreal.

HI folks,

I'm sharing my latest southern DSO target, and one of my favourite ones: the Tarantula Nebula (NGC 2070). Located at Doradus constellation at only 161,000 light-years away from Earth in the Large Magellanic Cloud (LMC) galaxy, the Tarantula Nebula is the largest and brightest star-forming region in the Local Group, the galaxies nearest our Milky Way. A huge region of ionized gas surrounding a collection of newly-forming stars.

Ands yeah, it's not about gradients or stray light as you might initially think. NGC 2070 is one of those few DSO objects where we can find "green" in space!

Eiffel Tower and the solar eclipse

Here is a picture of the eclipse see from Paris at its apogee that happened at 12h02 local hour.

For this picture I had to take two photograpies, one for the sun with a solar filter and one for the foreground because the sun was too bright to get its shape without a filter. I built a custom filter with an astrosolar sheet, It’s pretty simple and I was quite surprised by the results. I went to the Seine banks in Paris to align the eclipse with the Eiffel Tower.

Equipment : Canon 6D - Samyang 135mm - Astrosolar filter
Pic with filter : ISO-100 - 1/20sec - F5
Pic without filter : ISO-100 - 1/1000 sec - F5
