The Olsen-Sidonio Centaurus A Extreme Deep Field

Copyright: Rolf Wahl Olsen & Michael Sidonio Click for a 7MB full resolution version
Rolf Olsen and Mike Sidonio are pleased to present here what we believe to be the deepest colour image in visible light ever presented of the entirety of the enigmatic and famous galaxy NGC 5128.
This image represents a mammoth collaborative integration time of 140 hours worth of exposure using two different imaging systems:
Rolf Olsen: 120 hours using a 10" Newtonian and QSI CCD camera from the outer suburbs of Auckland New Zealand and reaches to at least magnitude 25.45
See Rolf's gallery Centaurus A Extreme Deep Field - 120 Hours for full details.
Mike Sidonio: 20 hours using a 6" Starfire refractor and FLI CCD camera from perfect dark skies at Wiruna, North West of Lithgow Australia and reaches beyond magnitude 24
See Mike's gallery Centaurus A - the ultimate collection for full details.

OMG David Malin would be so proud of you guys!! What an amazing age we live in where both professionals and amateurs can contribute to our understanding of the universe! Hey Mike, you should try a 50 hour exposure with your new scope!!SkyViking wrote:The Olsen-Sidonio Centaurus A Extreme Deep Field

Wave like NLC
Last year in July I photographed some interesting NLC for almost 1.5 hours and made a timelapse.
The clouds appear to roll like waves on a stormy sea.
The time lapse is on Vimeo: https://vimeo.com/67714622 .

Sun in H-Alpha light inverted
Copyright: Álvaro Ibáñez Pérez
Personal Web: http://www.flickr.com/photos/kokehtz/
The image was recorded in a single color of light called Hydrogen Alpha (H-Alpha), inverted, and false colored. The gradual brightening towards the Sun's edges is caused by increased absorption of relatively cool solar gas and called limb darkening. Spicules cover much of the Sun's face. Several scintillating prominences protrude, while prominences on the Sun's face are seen as light streaks. The most visually interesting of all are the magnetically tangled active regions containing cool sunspots.

Sun in CaK light, H-Alpha light and White light
Copyright: Álvaro Ibáñez Pérez
Personal Web: http://www.flickr.com/photos/kokehtz/
The Sun emits light full range. Until recently, only professionals telescopes could observe the Sun in several wavelengths.
Today in amateur telescopes can observe in 3 wavelengths: Cak, H-Alpha and white light.
In the CaK image above shows the Sun as a purple disk since it was taken in ionized calcium light. This is light from calcium atoms that have lost an electron. It peaks in the violet part of the spectrum (393.4 nm) and is sensitive to magnetic fields -- magnetically active structures are easier to detect with this light. Places where moderate magnetic fields exist show up brightly (hot), whereas high magnetic fields are quite dark (cool). The brightest regions are found in the chromosphere and are known as "plages. The darkest regions are sunspots -- on the Sun's "surface" or photosphere. These "spots" approximately 1,500 - 2,000 K cooler than their surroundings. Granulation, over much of the photosphere, can also be identified.
In the H-Alpha picture, several prominences are visible. Active areas of the Sun are marked by dark plages.
In the white light picture, you can see the photosphere, spots with umbra and penumbra, also solar faculae are visibles.

The darkest regions are sunspots -- on the Sun's "surface" or photosphere. These "spots" approximately 1,500 - 2,000 K cooler than their surroundings. Granulation, over much of the photosphere, can also be identified.

Stars over Borrego
It's that wonderful time of year again, when the brightest part of the Milky Way returns for another season of great stargazing! Here it appears arched over one of many impressive metal sculptures scattered around the desert community of Borrego Springs, California. With a summertime population of far less than 3,000 and surrounded by a thousand square miles of the Anza-Borrego Desert, our community doesn't produce much light pollution and enjoys one of the darkest skies in Southern California. In fact, it is the state's only International Dark Sky Community. But on this night, the power to the entire town was out, making it even darker than normal. The word "borrego," by the way, is Spanish for bighorn sheep which inhabit the hills around town and frequently can be seen at local canyon watering holes.
