I went out and took some shots of Saturn, which was low on the western horizon after a hot day in Utah. None of the data was really usable, but I tried anyway.
I post this to demonstrate how stacking data can help, even if the source info is very noisy. By stacking frames I increase the signal-to-noise ratio, meaning that each frame has a little noise and a little info. The info will come through over and over in the same places, and the noise is always just random. When stacked, the noise cancels itself out, and the real image comes through.
Well, it's trying to be a Focus stacking image of a dandelion but my technique is flawed at the moment

Chairs Stacked at 1 Air Street, London. These chairs felt like an art installation. I had to take photos of them as if they were.

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.
