SMC - Continuumsubtraction

Post by FrankSackenheim » Fri May 12, 2017 9:21 pm

Hello,

i gave a try on whats called continuumsubtraction. I´ve heard this term for the first time from british astrophotographer Paul Beskeen. The Idea is to subtract an image of a continous spectrum from a narrowband image, to qualify the real narrowband emitter. This is a "Poor Men´s Method" as professional astronomers do it a little bit more complex (see papers on continuumsubtraction from science archives).

Well here is what i got. I present a RGB (OIIIHa) image as well as the continuum subtracted Ha and OIII Images, and an colormix of both oh them. Also i link an annotated image.

SPIRAL GALAXY M106


M106 also known as NGC4258 Is a galaxy in the constellation Canes Venatici. It is about 25 million light years away, and approximately 130,000 light years across. The unusual central glow makes M106 one of the closest examples of the Seyfert class of galaxies where vast amounts of glowing gas are thought to be falling into a central massive black hole.

M106 has a water vapor megamaser (the equivalent of a laser operating in microwave instead of visible light and on a galactic scale) that is seen by the 22-GHz line of ortho-H2O that evidences dense and warm molecular gas.

It is one of the largest and brightest nearby galaxies, similar in size and luminosity to the Andromeda Galaxy.

M106 has also played an important role in calibrating the cosmic distance ladder. Before, Cepheid variables from other galaxies cannot be used to measure distances since they cover ranges of metallicities different from the Milky Way's.

Center

The image shows the central part of the Galaxy. The brightest part of the Milky Way sandwiched between the constellations of Scorpio, Sagittarius and Ophiuchus. Here is the highest concentration of stars and dust clouds. We can also see a lot of red hydrogen nebulae.

The Great Eruption in the constellation of Carina
http://www.facebook.com/astrofotografia
Copyright: Adam Jesionkiewicz Hi resolution version is here:
http://astropolis.pl/gallery/NGC3372-Et ... lor_HF.jpg

Description:

In 1827 Burchell specifically noted Eta Carinae's unusual brightness at 1st magnitude, and was the first to suspect that it varied in brightness. John Herschel made a detailed series of accurate measurements in the 1830s showing that Eta Carinae consistently shone around magnitude 1.4 until November 1837. On the evening of December 16, 1837, Herschel was astonished to see that it had brightened to slightly outshine Rigel. This event marked the beginning of a roughly 18-year period known as the Great Eruption.

Eta Carinae is probably the greatest treasure of the southern sky. It is also the first object on which you will direct your telescopes if you want to admire its beauty. Moreover, to see the surrounding nebula, you do not really need anything. Under good conditions it is visible to the naked eye.

A star, located 7,700 light-years from Earth, is actually a stellar system composed of at least two components. Their mutually reinforced glow is millions of times brighter than our Sun, and is primarily responsible for lighting up the surrounding matter. It is finally one of the most beautiful nebulas you can observe. It's called Carina. Like other objects of this type, it is a active star-forming region.

It is difficult to find in the sky a more diverse object to observe. You will find reflection, emission, dark, dust, and other nebulae in it. All this you can see on my photo taken in the multi-spectral technique (gathering light emitted by ionized gases: oxygen, hydrogen and sulfur).

This picture cost me a lot. 12 thousand kilometers and 72 hours of travel. 3 nights struggle to collect photons. 15 hours of raw material processing. The result is a photograph that I undoubtedly point to as the groundbreaking and best astrophotography of my decade-long career. In this field, achieving the level of the image we dreamed up is extremely difficult. This time I have the impression that I look at the picture exactly what I wanted to do.

When working with narrowband filters, then trying to balance them in a graphical application, is such a magical moment when the monochrome picture blossoms with a color gamut. This is the moment in which the author himself cannot admire the scale of beauty of cosmic creation. Because we do not create it. Modestly we only record and interpret.

The work, however, is not ours.

Cassini's "Grand Finale" Saturn Portrait (April 13, 2017)
Image
Cassini's "Grand Finale" Saturn Portrait (April 13, 2017) Ian Regan

In the early hours of April 13, 2017, a veteran NASA probe captured this breathtaking and unique visage of the Saturnian system as it coasted through space in the shadow of the gas giant.

Using its Wide-Angle Camera (part of the Imaging Science Subsystem), Cassini snapped 96 individual digital photos: these images consisted of Red, Green, and Blue-filtered frames, covering a total of 32 ‘footprints’. These 32 color frames were painstakingly combined to produce the final mosaic.

The veteran spacecraft took nearly four hours to collect these data. In that time, Cassini was slowly cruising away from the planet, en route to apoapse (the point farthest from Saturn in any given orbit) of Revolution 269. The distance to the planet increased by 82,000 km in that time, and in the end, the distance to the cloud-tops equalled 650,040 km.

All components of the main ring system are visible, seen here illuminated from behind: a vantage point technically known as a ‘high-phase angle’. In this geometry, a peculiar reversal happens: the thinner and more translucent rings shine out brightly, while the more opaque and thicker regions are relatively dark.

Only two moons — Janus and Mimas — can be picked out in this uncalibrated and compressed data, in addition to a red-giant star in the constellation of Gemini: Tejat (μ Gem).

Capella rising

Credits: Adrien Mauduit

Capella, actually composed of four stars, situated in the Auriga constellation is the 3rd brightest star in the northern celestial hemisphere, and the 11th in the whole night sky. As the picture suggests, it rises just above the northern horizon at this time of year in Denmark. I took the shot at 2:30 am on May 18th 2017 on Høve beach in Odsherred, as we were transitioning from the astronomical dawn into the nautical dawn. As I was looking for a sign of noctilucent clouds, even the highest cirrus reflect some of the light emanating from the sunrise hundreds of km from there. Notice of they seem to make the night sky glowing and alive!
