Railroad ties are stacked in a corner of a parking lot for the New London (Ohio) town reservoir as an eastbound CSX coal train passes in the background. I'm not sure why these ties were stacked here.
South Stack is famous as the location of one of Wales' most spectacular lighthouses, South Stack Lighthouse. It has a height of 41 metres (135 feet). It has a maximum area of 7 acres.
Until 1828 when an iron suspension bridge was built, the only means of crossing the deep water channel on to the island was in a basket which was suspended on a hemp cable. The suspension bridge was replaced in 1964, but by 1983 the bridge had to be closed to the public, due to safety reasons. A new aluminium bridge was built and the lighthouse was reopened for public visits in 1997. Thousands of people flock to the lighthouse every year, thanks to the continued public transport service from Holyhead's town centre.
There are over 400 stone steps down to the footbridge (and not, as local legend suggests, 365), and the descent and ascent provide an opportunity to see some of the 4,000 nesting birds that line the cliffs during the breeding season. The cliffs are part of the RSPB South Stack Cliffs bird reserve, based at Elin's Tower.
The Anglesey Coastal Path passes South Stack, as does the Cybi Circular Walk. The latter has long and short variants; the short walk is 4 miles long and takes around two hours to complete. Travelling from the Breakwater Country Park, other sites along the way are the North Stack Fog Signal station, Caer y Tŵr, Holyhead Mountain and Tŷ Mawr Hut Circles.

Stack of 5 sea urchins on a bed of sand.
I like the way the white dots on the different size urchins line up with each other.

The South Stack Lighthouse is built on the summit of a small island off the north-west coast of Holy Island, Anglesey, Wales. It was built in 1809 to warn ships of the dangerous rocks below. The 91-foot tall lighthouse was designed by Daniel Alexander.

Sometimes after a tough day where everything you tried to do seemed to flounder or fail, just go back to your childhood. Lay back on the grass and simply look at the sky. Search for animal shapes or people's faces and let your troubles float away for awhile. (Rooster Rock State Park DSC_9790.jpg)
While walking along Sunset Beach in Vancouver, I found a lot of rocks stacked up in a weird way. Some people said they're miniature inukshuk's, but they're kind of missing the arms and legs... But they were still very interesting none the less.
Anyway, I'm slightly disappointed that I didn't get more of the sky and that warm light though.
Sea Stacks, Bandon Beach, Oregon.
This image was shot during the early morning hours. At this time, these sea stacks were perfectly lit up with an orange glow. The early morning sun was casting long shadows over the beach and the sky started to brighten up with a typical blue hue. I used a HDR image for the foreground that provided the realistic sharp image I was looking for. For the sky, I used a frame that was under exposed two stops. I composited these two images in normal blend mode in CS6. For a change, I did not overwork this image and I left it as real as I could. A lonely photographer (DW) gave a much needed scale to this image!

About equatorial mounts and their maintenance
Credit: Giuseppe Donatiello
The Earth rotates on its axis at about 465 m/s (about 1,670 km/h) at the Equator. This is a remarkable speed that we can perceive by watching the setting Sun disappear behind the horizon in a few seconds.
It is more difficult to perceive the rotation by looking at the stars without having a reference, however a trained eye is able to notice the slow and constant movement.
We notice this when we try to take a photo of the night sky, especially with focal lengths greater than 50mm. With panoramic lenses, in fact, it can take several seconds before recording the blurred stars with the camera on a tripod.
Even with a small telephoto lens, 2-3 seconds can be enough to have annoyingly stretched images. With longer exposures, you even get dashes of length proportional to the seconds used. With focal lengths of about a meter and above, the images will be stretched by just a fraction of a second, assuming that the brightness of the sources is sufficient to record something.
Even the brightest stars are damned faint, so it is mandatory to take exposures of a few seconds or more to capture their light. The problem is that the Earth rotates in the meantime and, if we do not compensate for this movement, they will produce marks on the sensor with a thickness proportional to their brightness. It may seem like a simple task but it is not.
The first step is from a fixed tripod to a device that allows us to replicate the Earth's rotation. In essence, the device must give the optical/photographic complex a movement from east to west equal to the Earth's angular rotation speed, with the greatest possible precision and in such a way as to keep the source virtually still on the sensor. This device is called an equatorial mount.
An equatorial mount has three degrees of freedom and allows us to tilt the hour axis, arranging it parallel to the Earth's axis. The hourly movement is instead entrusted to a motor capable of giving the axis an angular speed equal to about 15°/h.
If all the settings have been done correctly, we will get an image like the one below, with the stars and the planet Mars at the center of the Presepe cluster still. Above, however, the motor was deliberately "forgotten" to be turned off and the stars produced dashes, as explained above.
As we can see, even 30 seconds of exposure are barely enough to show the brightest stars in the cluster. To capture the very faint light of nebulae and galaxies, it will therefore be necessary to collect photons with a certain number of shots that we can add together with specific software. This allows us to improve the signal/noise ratio and have richer images.
The untracked images are not "defective" or "wrong". Indeed, we can exploit the Earth's rotation to take creative shots that recall the passage of time. A "strip" is also useful for estimating the brightness of a source by comparing it to others of known brightness: the eye estimates the differences on dashes better than on points.
With this method I estimated, for example, the magnitude of the supernova in M101 at 10.6, a value very close to that recorded with photometry, just to remember that astrophotography is primarily an investigative tool.
A good astronomical photograph is always the sum of knowledge, technique, experience and also creativity. Always have respect for it even when the result may seem unflattering.
Among the natural rock formations, there is stonework that was carried out by convicts who cut and stacked the stone blocks to build the pathways.

The stone piles popular in many traditions of Buddhism, it is said that first stupas were simply stacked stones. There are some legends of "saints" hiding teachings and sutra translations in mountain altars to be discovered hundreds of years later, which were just stones stacked up beside paths. For some these also accompany the offerings to the to the Buddhas and Bodhisattvas implying that the strength of the offering is in the intention, not the ornateness of the altar on which we place it.
Due to the work and personal commitments it has been a long time that I logged into Flickr and I think this will continue on for a while and I will stay away for some more time. This is my offering to all my Flickr friends. Please accept my apologies for not visiting your stream or not responding to your comments. Unfortunately my absence will continue for some more time, please bear with me for a while. Have a great time and a wonderful time.
