"How hard to realize that every camp of men or beast has this glorious starry firmament for a roof! In such places, standing alone on the mountaintop, it is easy to realize that whatever special nests we make--leaves and moss like the marmots and birds, or tents or piled stone--we all dwell in a house of one room--the world with a firmament for its roof--and are sailing the celestial spaces without leaving any track." - John Muir
This was my first serious try at night sky photography. I waited for dark, then took my tripod and wide-angle lens out to Balanced Rock at Arches NP. I tried maybe 50 different shots before I got one that had potential. So much fun.
The three brightest objects in the night sky: The Moon, Venus and Jupiter appearing close to each other on June 20, 2015.
Some cosmic beauties
Remember : "Stars you seeing today may be dead million years back "
For example, light from the Andromeda galaxy (M31), the nearest large galaxy takes about 2.5 million years to reach us, so we are seeing what it looked like 2.5 million years ago.
My AI info said " Around 2.5 million years ago, several human ancestor species lived, including Australopithecus garhi and Homo habilis. This period also saw the emergence of the Homo genus from its australopithecine ancestors. Other species like Australopithecus africanus and an unnamed australopithecine species were also present "

Eu passei a acreditar que cada um de nós somos anjos enviados por Deus, mas quando somos atraídos pelo mundo, por suas paixões, vaidades e desejos, nos esquecemos de onde viemos, perdemos a inocência. Cabe a nós mesmos nos lembrarmos de nossa origem, o que muitas vezes parece ser difícil. Nossas memórias se perdem com o tempo, mas podemos sentir a essência de nossas asas dentro da alma. O cheiro da paz.
Nossa missão é ajudar os outros a se lembrarem. Os que se recusam a aceitar suas raízes. É um compromisso difícil, somos limitados pelo cérebro, conseguimos pensar apenas na lógica, no que vemos ou tocamos. Mas, se quisermos podemos sentir Jesus através de todos os sentidos do corpo humano.
Nós somos anjos, nada menos que a perfeição criada por Deus. Quebre-se. Rasgue-se. Liberte-se dessas escamas, é possível voar! Deixe suas asas crescerem, não as corte mais com as feridas da vida. Permita-se experimentar o sabor das nuvens, para que então possamos viver em paz, desfrutando desse mundo maravilhoso que Deus nos presenteou. Sorrindo sem máscaras. Amando sem julgamentos.
Entregue-se ao Amor.
A couple of months ago when Ian got his 12" inch Dobsonian telescope he was given this Celestial Globe.
Camera: Nikon FM-2
Lens: Nikkor 50mm f1.4 AIS
Film: Fuji Velvia 50
The skies in Australias outback are INCREDIBLE. Being so remote there is virtually no atmospheric pollution so they are crystal clear. This is the South Celestial Pole - by using the Southern Cross and Alpha/Beta Centauri its position in the sky is easily determined. By drawing a line to the horizon from that point you have due south.
The green colour in the sky is due to Reciprocity failure which requires exposure compensation (usually adding a stop or 2 to the metered EV value) and also causes this colour shift (green in this example) Most films are designed to be exposed between 1 second and 1/10000th sec. Anything outside these parameters causes this effect.
By using faster speed films you can decrease the exposure time but of course you then get smaller arcs as the stars arent travelling as far across the frame. I really dont know of any way to limit the green colour cast effect in Velvia other than using a magenta colour correction filter or colour correcting in post.
Tungsten balanced film will have a different colour shift. Provia 100F requires no correction at all for exposures shorter than 128 seconds wheras Velvia exhibits colour shift after 4 seconds.
Ringforts
Ringforts are fortified settlements that are generally deemed to be from the Iron Age, Early Christian or possibly the Early Medieval period in Northern Europe, especially Ireland. They are also known as ráth, caiseal, cathair and dún in the early Irish sources, and by caher in contemporary archaeological literature of Ireland.
A ráth (anglicised rath), was made of earth, caiseal (northwestern Ireland, anglicised cashel) and cathair (southwestern Ireland) were built of stone. A dun is a more prestigious site, the seat of some kind of ruler, the term is applied to promontory forts as well.
In terms of quantity, distribution and access, no historical or archaeological record of the Early Medieval Period in Ireland comes close to the ringfort. Over 45,000 sites have been identified as ringforts throughout Ireland and it is generally accepted that in the region of 60,000 ringfort sites can be identified. It is probable that due to intensive farming methods, the levelling of field and expansion of urban areas than many more were originally built but have been lost to us today, but through the use of early Ordnance Survey maps and aerial photography many previously unknown ringforts have been discovered. Also, the extensive archaeological work that has accompanied the large road-building programs in Ireland have uncovered many unknown faeryforts and will probably continue to do so.
Despite regional variations in the density of ringforts particularly in the areas of Meath and traditional Leinster where there are comparatively few ringforts, they are generally a feature common throughout the country, with a mean density of just over one ringfort within any area of 2km². Despite their number, consensus has yet to be reached on two of the principal issues relating to ringforts, firstly, when they were built and secondly, what their function was.
