Abell 35 - A Stromgren Sphere

Abell35 by Logan Carpenter, on Flickr

Abell 35 (SH2-313).
This nebula has a very low surface brightness and although often listed as a planetary nebula, other evidence suggests this is a Stromgren sphere (the Rosette nebula is also such an example).
At the center of this nebula is a binary star system consisting of a fast rotating subgiant and a companion white dwarf star. Whilst it resembles something like the Helix nebula, it differs in that the outer red glowing shell results from the ionization of the interstellar medium by the white dwarf. In the more central OIII region you can see a "bow shock wave" believed to be due to a wind from the fast rotating subgiant interacting with the inner zone of the nebula.

Barnard 87 (aka The Parrot's Head Nebula)

Also known as LDN 1771 or the Parrot's Head Nebula, is located 3 degrees north from Messier 7. It has a rich star field background which brings contrast to the dark area. Edward Emerson Barnard was an American Astronomer born in 1857. Being an pioneer astrophotographer he complied a list of Dark Nebulae known as the Barnard Catalogue with 370 objects. The list was published in 1919. Most of his work was done by taking photographs of the Milky Way. His best known discovery was the Barnard Star in 1916.

Below are 3 selected views from the Orion constellation. A 25° x 34° field was calculated from a larger set of data. Results at a resolution of up to 10 arcsec/pixel are presented at http://www.simg.de/nebulae3/ori-06.html

In the first two views H-alpha (including red continuum) is mapped to red, blue continuum is mapped to green and red continuum (without H-alpha) is mapped to blue, i.e. H-alpha emission nebulae are shown red and reflection nebulae appear blue to green.

We experienced one epic night of Sprite shooting down at McDonald Observatory during our workshop last week! The evening started off with an absolutely beautiful sunset as storms rolled through, so conditions were prime for Sprite hunting. Pictured here are a few of the brighter Sprites captured during a timelapse video that I will be sharing. The phenomenon of Sprites is so incredible as they occur between 40-90 miles above thunderstorms. For perspective, commercial jets fly at about 6 miles up. On the bottom left of the frame is the Hobby-Eberly Telescope, an absolute monster 10-meter telescope.

The Dragon Egg

The Dragon Egg (NGC6164) by Logan Carpenter, on Flickr


The Dragon's Egg
NGC6164 is an emission nebula, 4200 light years away created by a hot, luminous O-type star approx 3-4 million years old and 40 times as massive as out sun. The red emission nebula surrounding the star is approx 4 light years across and has a bipolar symmetry similar to planetary nebula (although this is not an example of planetary nebula that surround dying stars). There is also a faint outer halo (blue) expanding into the surrounding interstellar medium likely formed from an earlier active phase of the central star. (ref NASA).

NGC6164 is located just below NGC6188, the Fighting Dragons of Ara.

The image is a mix of 5min, 10 min and 20 min exposures.

OIII 9.6 hours

CATEGORY: SINGLE SHOT
STORY:
After an early night with rain, the Great Magellanic Cloud appears shining in the skies of the Iguaçu Falls.
The Magellanic Clouds are some of the objects of the night sky seen exclusively in the southern hemisphere. Being in places with low degree of light pollution, looking towards the south celestial pole it is possible to identify the two galaxies with the naked eye.

Hi, all. Beautiful eclipse from Bariloche this morning. Very dark, very cold and very windy (I had to trash 75% of the shots because of the wind). Here's a couple of the best. The Moon is setting behind Mt. Catedral.

Regards,

Guillermo

The Iris Nebula

The Iris Nebula is circumpolar from my home, which means it’s always visible above the horizon. So it’s a project to continually add data to, when other objects sink below the horizon during the night.

So far I’ve collected a little over 11 hours worth of data, taken with two different camera’s, so it was about time to combine it into a proper image.

I’m really happy how I was able to bring out the faint dust clouds, something which wasn’t really possible with my last attempt.

De details:
The Iris Nebula (also known as NGC 7023 and Caldwell 4) is a bright reflection nebula in the constellation Cepheus

Lunar Eclipse with Mount Jefferson.
This is a single frame shot of the Moon at approx 04:45 on Wednesday morning while the Moon was leaving the Umbra. The morning sky allowed me to shoot Mount Jefferson and the Moon in a single shot. It was a super viewing experience, and well worth the long drive and lack of sleep.

Total Lunar Eclipse from Auckland, New Zealand

Total lunar Eclipse by Logan Carpenter, on Flickr

The total lunar eclipse on the 26/5/21 taken from Auckland, New Zealand
This is a composite image consisting of several images (lucky imaging consisting of 10sec videos) taken at different stages of the eclipse through a Skywatcher Esprit 120ED with an ASI294mcPro camera.
The second to last moon phase image is a blend of two images taken at around the same eclipse phase but exposures done for the bright side and the dark side.
