Singapur tiene algunos de los elementos arquitectónicos más bonitos e impresionantes del mundo.
En primer plano en el lado izquierdo se ve el "Puente del ADN". Es un puente peatonal en forma de curva que permite atravesar desde la parte de la Marina Bay más próxima al Singapore Flyer hasta la zona del Marina Bay Sands Hotel. El puente recibe su nombre de la doble hélice que representan las dos espirales de acero que lo estructuran, recordando a la estructura del ADN. En el suelo se puede apreciar luces verdes y rojas. El par de letras c y g son iluminadas de verde y el par a y t iluminados en color rojo. Representan las iniciales de las cuatro bases del ADN, citosina y guanina, adenina y timina.
Al fondo el imponente Hotel Marina Bay Sands uno de los edificios más emblemáticos de Singapur.
En el lado derecho con forma de flor de Loto, el Museo de Arte y Ciencia de Marina Bay Sands.

A tall sculpture named 'Helix' in Central London.
Helix (1998) by Eilìs O'Connell, founder of The Irish Sculpture Factory, at One Curzon Street, Mayfair, London W1.
Ésta no es una fotografía preparada ni tan siquiera planificada, fué apuntada por casualidad a principios de Octubre, mientras realizaba las primeras pruebas en remoto de autoenfoque y deriva en el observatorio.
Recientemente me di cuenta de que tenía 4 tomas de 300s iguales, me dió por probar a apilarlas, sin tomas de calibración, y de entre el ruido emergió una bonita y natural nebulosa muy digna de ser publicada, a la que prácticamente no le hacía falta cosmética ni procesado para brillar con luz própia.

Helix pomatia, common names the Roman snail, Burgundy snail, edible snail or escargot, is a species of large, edible, air-breathing land snail, a pulmonate gastropod terrestrial mollusc in the family Helicidae. It is a European species. In the English language it is called by the French name escargot when used in cooking (escargot simply means 'snail'). Although this species is highly prized as a food, it is difficult to cultivate and rarely farmed commercially.
I used a custom-made camera rotation tool (CRT) to shoot inside the interior of Helix Pedestrian Bridge. A single exposure with the lens cap replaced between each 30 degrees rotation. Camera settings: f/16 - ISO 100 - 409 seconds
Location: Helix Pedestrian Bridge, Myrtle Edwards Park in Seattle, WA
سديم اللولب، هو من اكبر و اقرب السدم الكوكبيه الينا حيث يبعد حوالي ٤٥٠ سنه ضوئيه. هذا السديم الجميل يشبه العين في السماء. يمثل هذا السديم المراحل النهائيه في حياه النجم، حيث يتقلص النجم بدرجه كبيره و يطلق غلافه الخارجي ليكون نجم ابيض قزم. ينتج عن هذا النجم طاقه و اشعاعات قويه تؤدي الى تأين الاوكسجين باللون الازرق و الهايدروجين باللون الاحمر. Helix nebula NGC 7293 is the largest and closest planetary nebula to us. It’s about 450 ly distance. This beautiful nebula resembles an eye in the space. This form of nebula represents the final stages in the star life where the star repelled its outer shell into the space and shrink to form white dwarf star. This star emits very powerful stellar winds & radiations, that ionize Oxygen & Hydrogen gases to emit Blue & Red colors respectively. Gear setup: Celestron HD11 f/7, iOptron CEM70G, ZWO 2600MM, Antlia Ha, Oiii 3nm filters. Lights Ha 70 x 300sec, Oiii 80 x 300, total exposure 10 hours. Captured by NINA, PHD2. Stacked in APP. Processed in PI & PS. Imaged from sky Bortle 4.
This beautiful large planetary nebula is located in the constellation Aquarius. The Helix Nebula is approximately 695 light years from Earth, and presents a fairly large target, almost one-half the diameter of the moon.
My intent was to merge both traditional RGB and Narrowband into a hybrid image using 6 filters to reveal three things. The first included the amazing cometary knots extending away from the central star in a radial direction. Their scale is simply amazing as most are believed to be about the size of our solar system.
The second stems from my fascination of galaxies. I wanted to reveal the many galaxies located both within the core and throughout the outer halo extending away from the Planetary Nebula.
The final goal was to retain the lovely teal colour of the core and reveal the beautiful colours in the stars surrounding NGC 7293 including the bluish central star. The rare teal colour found in planetary nebula can often be removed during imaging processing.
The total time for this image is around 64 hours.

At the heart of the Château de Chambord is a double helix staircase reputedly designed by Leonardo da Vinci. The two opposing staircases wind around a central illuminated well, up to the top of the chateau where they meet in the roof. Legend suggests that this configuration was designed so that the king, could arrange clandestine meetings with his mistresses at the top. The steps are supposed to be sufficiently shallow that a lady would not tire in ascending them.
Hope you have enjoyed the weekend. Thanks, as always, for stopping by and for all of your kind comments, awards and faves -- I appreciate them all.

This is a second look at this Nebula with a whole new Camera QHY183C a replacement for the ZWOASI183MC that was faulty. I could focus automatically with this camera hence the detail in the eye is much better than the first one with the ZWO. This camera took a bit to get use to as I had to change wires and ports on the computer to get this to run and download photos.
35 shot 10 min each till the tree got in the way.

La nebulosa de la Hélice, nebulosa Helix , NGC 7293 o el ojo de Dios como es popularmente llamada , es una nebulosa planetaria en la constelación de Acuario, a unos 680 años luz de distancia. Es una de las nebulosas planetarias más próximas a la Tierra y fue descubierta por Karl Ludwig Harding antes de 1824. Su aspecto es muy similar a la nebulosa del Anillo (M57) y sus características físicas son parecidas a las de la nebulosa Dumbbell (M27).
Esta nebulosa es un ejemplo de nebulosa planetaria formada por una estrella similar al Sol en los últimos estados de su vida. Los gases expulsados por la estrella aparecen desde nuestra perspectiva como si viéramos una hélice desde arriba, de donde proviene su nombre. La estrella remanente es una enana blanca. La edad de la nebulosa, basada en su ritmo de expansión, se estima en unos 10 600 años aproximadamente.
A pesar de su gran tamaño aparente, es un objeto difícil de ver debido a su difusión, requiriendo cielos oscuros y el uso de instrumentos lo más luminosos posible

The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, most likely before 1824, this object is one of the closest of all the bright planetary nebulae to Earth. The distance, measured by the Gaia mission, is 655±13 light-years. It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are in turn similar to the Dumbbell Nebula, differing only in their relative proximity and the appearance from the equatorial viewing angle.[5] The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture, as well as the "Eye of Sauron".

The London School of Economics Library recently invited me back to photograph their interior, and having visited twice over the past year, most recently last December, it was fun to come back for a third time and try to capture the location from a different vantage point.
Even late in the evening and outside of university term time, the library was filled with visitors. While I waited for the place to quieten down, I selected a spot on one of the middle levels, looking towards the spiral ramp that circles the lift shaft throughout the atrium. My aim when shooting this scene was to try to convey the elegance of the lines, curves and complementing patterns, and at the same time a sense of the scene’s energy and creativity. As people gradually made their way down the ramp, two people caught my eye: one lady wearing a red head scarf, and another who was one level higher, leaning on the balcony and absorbed in an intense conversation on her phone. I was torn over which one to keep in the final image, and in the end settled on both, as I felt this reflected the depth and scale of the location, and perhaps more importantly how much was going on in the library at the same time.
The final image is a mixture of exposures: two sets of nine bracketed exposures, blended in Photoshop using luminosity masks to balance the highlights and shadows, and then combined to mask out lifts as they moved up and down the lift shaft. I then captured an additional exposure for the lady walking down the ramp, which required a much faster shutter speed and therefore a higher ISO and a wider aperture.
With the exposures blended and the emphasis on a high-key finish, I shifted the colour balance towards a palette with hints of cyan and green in order to complement the pristine surfaces and brilliant-white tones across the building. While the image was already bright and airy, I wanted to play this up even more, so I added a low-opacity Gradient Map and set the blend mode to screen, excluding the highlights while further brightening the midtones and shadows. Finally, using Nik plugins, I gently amplified the whites and added a Pro Contrast filter, which helped to give the details a little more definition and made the image pop.
The library wanted images without people so I’m unlikely to be able to supply this take to them, but it was a fun exercise and a joy to photograph, and also an interesting exploration of how people visiting a location can interact with their surroundings and complete the scene.

And this is just to name some exotic countries where I never have been.
I am really happy to get to know you a bit and be a part of your life and culture. You cannot imagine how much this inspires me.
Today is a shot from Singapore. This is Marina Bay and the Helix Bridge. The shot has been taken in 2010. I am sure it looks totally different today!
Have a great week all you people.

I captured this view of NGC7293, aka the Helix nebula, aka "The eye of Sauron", using a remote telescope.
As my equipment is not with me at the moment, I had to find another way to combat astrophotography withdrawal.
I could rent some time on a 60 cm telescope in Chile.
