Its a freezing cold night here in Ireland with a clear sky and virtually no wind - perfect for hunting for star trails. I had two locations in mind - this is the second of the two and a familiar subject, I've photographed the Horseman on many occasions this year.
My take on star trails is pretty much the same as everyone else - there are two popular techniques, a single long exposure or multiple exposures combined in Photoshop. Each of these has its place. The single exposure is good for shooting in near darkness with no strong light sources. Multiple exposures are necessary if there are additional light sources that will possibly blow-out in a long exposure (street or window lights etc).
This is a single 30 minute Exposure. Shot in RAW and converted in PS, the image is pretty much straight from the camera (I did crop the image as some light contamination had crept into the RHS, also a simple border is added).
One of the most difficult aspects of virtual zero-light photography, is trying to get your focus right, a few test shots using a flash is helpful here - or for purists, come at dusk and set up your shot, lock down focus and wait for darkness. The exposure is down to experimentation after that, I've tested a few settings and for this shot used ISO 200 at f/5.6.
The illumination of the sculpture was created naturally as a result of ambient light coming from traffic along the N4 (no PS dodging or burning here). In total about 6 cars passed during the exposure. It was a stroke of luck to limit the exposure to 30 minutes as any additional light hitting the sculpture might have caused high-lights to blow.
More from this sitting to follow.
Hay un tipo de fotografía nocturna que siempre impacta cuando la vemos. Y no es otra que incluir en nuestra composición la estrella Polar.
Como sabéis, la Tierra, gira alrededor del Sol, pero a su vez tiene una rotación sobre un eje imaginario.
Este eje, digamos, apunta al norte, por lo que si realizamos una fotografía de larga exposición con la estrella Polar en nuestra toma, lo que obtendremos será una imagen de las estrellas girando alrededor de la misma... Aunque realmente las estrellas no están girando, claro, somos nosotros.
One type of night photography that always hits when we see it. And it is none other than our composition include Polaris.
As you know, the Earth revolves around the sun, but in turn is a rotation about an imaginary axis.
This axis, say, points north, so if you take a long exposure photography with Polaris in our decision, what we will have is an image of the stars rotating around it ... Although the stars really are not turning, of course, we are.
20 Jahre Astronomie und das ist mein erstes Star Trails Bild. Es entstand am Coesfelder Berg als ich Polarlichter fotografieren wollte im Februar. 256 Einzelbilder mit der Canon EOS 6 D, 800 ISO und 10 Sekunden Aufnahmezeit. Star Trails zeigen die Wanderung der Sterne als Striche.
My first attempt led to a foggy lens after 58 shots of a planned 300 shot stack. Thought I would process anyway and was pretty happy with the result. Porcessed with Photoshop as I couldnt get Starstax to work on my Mac. Definitely something I will be trying again.
After my attempt to get a meteor photo I was left with hundreds of photos from the same perspective. Star Trail lemonade! Added the foreground from a previous shoot that was taken at sunset. Edited the tones and exposure to make it look as if it was taken at night.
As I'm moving house in about a month this may be the last trail I take from the South West London home I've lived in for the past 11 years. My new garden is 3 times the size so less of a problem with houses and trees but I'll miss this one nonetheless.

During a clear night, with a dear friend of mine, I finally managed to rotate the celestial vault...
Durante una notte serena, con un mio caro amico, sono finalmente riuscito a far ruotare la volta celese...
Par une nuit claire, avec un cher ami, j'ai finalement réussi à faire pivoter la voûte céleste ...
