Touching Eta Carinae

Story: Several days in a row photographing the night sky at the Atacama´s Desert. Great experience! In the moment I shot this picture I was alone, in the middle of nowhere, experimenting a scene that clearly looked like another world. The 33 feet sculpture 'Hand of the Desert ' helped to create an even more alien atmosphere. It was a unique photoshoot indeed.

It was already pass 4:00 AM and a certain tiredness knoked my door. I started packing since I still would had two hours drive ahead. Just before leaving, I looked back and saw this wonderful scene forming: the hand almost "touching" Eta Carinae nebulae and the Southern Cross constellation! What a view!

I pulled everything out and began the photographic process again, hoping to capture a unique view of our southern night skies, harmonizing with a gigantic sculpture. (Mario Irarrázabal is the sculptor)

The edge-on galaxy NGC 891 in Andromeda

The edge-on galaxy NGC 891 is found in the constellation Andromeda. NGC 891 is approximately 30 million light-years away and is similar in size to our own Milky Way galaxy. A prominent dust lane is seen in the plane of the galaxy with tendrils of dust seen above and below that plain. These dust tendrils may be due in part to supernova explosions. The image is a total of 11 hours of exposure through a 12.5 inch f/9 RCOS astrograph with a SBIG STF8300c CCD camera on a Paramount ME taken in Mayhill, NM on the nights of 13, 14 Oct 2016; 16 Nov 2017; 13, 15 Dec 2017, and 13, 19 Jan 2018 (33 X 1200 sec lights @ -15 degrees C; 18 darks, 128 bias; 128 flats). Processed in PixInsight 1.8.5.1353 Ripley (X64).

2 Novae in deep southern sky
Copyright: Tunç Tezel
[br]
In mid-January, the news of a nova in Musca arrived. According to the initial observations, this was a 7th magnitude object, bright enough to be spotted by binoculars. After peaking at around mag. 6.7, it started to fade slowly.
https://www.aavso.org/aavso-alert-notice-609
In 25th January, there was news of another possible nova in Circinus. This nova was reported to be a 9th magnitude object at discovery, but it gradually brightened to 7th magnitude in the following days.
https://www.aavso.org/aavso-alert-notice-613
This is the view of the deep southern constellations and Milky Way including the both novae, as seen from the rim of Kilauea Caldera, Hawaii. At the time of photography (31st January, 1410 UT, during the total Lunar eclipse), Nova Mus 2018 was at mag. 8.0, while Nova Cir 2018 was at mag. 7.5. Meaning, the annotated version has to include detailed insets for both novae, which could otherwise be lost amongst many other similar looking stars in the deep southern Milky Way.

WaterGlyph

This past weekend I visited this petroglyph, known as a waterglyph, along the Utah/Arizona border. Some theories says these were navigational markers The circle represents the horizon, the line the direction of site and the small circle within the circle is a water source or village. These petroglyphs are estimated to be at least 1,000 years old http://www.waterglyphs.org

Also, some said the Hopi used them in "Look up, Ceremonies". Waterglyphs were "Sacred Viewing stations" (http://dixierockart.webs.com/Technical% ... Glyphs.pdf)

The nigh was frigid and the landscape was desolate. I didn't see another living soul the entire time. However, it seemed as if at one time this was an important place, a place where things occurred.

The petroglyph points straight east to where the sun would rise and for me the rising moon, as seen sitting in the core of the milky way.

Places like this need to be kept as the are, far from city lights, and the noise of roads. We need places like this that allow us to have one foot in this world and one foot in the other.

This is my first photo in this style of this year. Hopefully more will follow. However, It's a challenge to do many in this theme.

Driving, finding the sites... Then trying to photograph the site in a way that I can be sure not to damage it. This usually involves predicting composition in the daylight, setting up the camera and leaving everything in place until the appropriate time.

Sometimes I'll program the camera to take photographs at a specific time, especially if I don't feel comfortable or if it seem disrespectful to be bumbling around at night. Other times I'll return at a certain hour and take the photo.

Usually these photos consume an entire weekend and I usually come away with a single image, sometimes two.

Messier 65

I downloaded the publicly available data from the LCOGT network and processed this image.

Data for this image was collected by a 1m telescope (1m-08) operated by the Las Cumbres Observatory telescope network at he McDonald Observatory. The Principal Investigator for this data set was BJ Fulton. Thanks for looking!

This field of very faint dusty molecular material is a challenge to image and forms part of the much larger Chamaeleon Molecular Cloud. This dusty material fills the constellation of Chameleon and beyond, in the far southern sky, not far from the South Celestial Pole.
