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.
Just after sunset, this view from my west balcony shows the crescent moon with Venus down to the right and Antares, a bright star, off to the left forming a triangle in the sky.
Struggling again with this prompt. The man in the moon was my answer.

The spiral galaxy appearing in this week’s Hubble Picture of the Week is named IC 3225. It looks remarkably as if it’s been launched from a cannon, speeding through space like a comet with a tail of gas streaming from its disc behind it. The scenes that galaxies appear in from Earth’s point of view are fascinating; many seem to hang calmly in the emptiness of space as if hung from a string, while others star in much more dynamic situations!
Appearances can be deceiving with objects so far from Earth — IC 3225 itself is about 100 million light-years away — but the galaxy’s location suggests some causes for this active scene, because IC 3225 is one of over 1300 members of the Virgo galaxy cluster. The density of galaxies in the Virgo cluster creates a rich field of hot gas between them, the so-called ‘intracluster medium’, while the cluster’s extreme mass has its galaxies careening around its centre in some very fast orbits. Ramming through the thick intracluster medium, especially close to the cluster’s centre, places an enormous ‘ram pressure’ on the moving galaxies that strips gas out of them as they go.
IC 3225 is not so close to the cluster core right now, but astronomers have deduced that it has undergone this ram pressure stripping in the past. The galaxy looks as though it’s been impacted by this: it is compressed on one side and there has been noticeably more star formation on this leading edge, while the opposite end is stretched out of shape. Being in such a crowded field, a close call with another galaxy could also have tugged on IC 3225 and created this shape. The sight of this distorted galaxy is a reminder of the incredible forces at work on astronomical scales, which can move and reshape even entire galaxies!
[Image Description: A spiral galaxy. Its disc glows visibly from the centre, and has faint dust threaded through it. A spiral arm curves around the left edge of the disc and is noticeably more dense with bright blue spots, where there are hot and new stars, than the rest. Opposite, the disc stretches out into a short tail where it covers a distant background galaxy. Around it, other distant galaxies and some nearby stars are visible.]

3) HOW I MET YOUR MOTHER
Use aquele esmalte queridinho de sua mamis - ou da figura materna da sua vida! <3
Só mesmo um desafio pra me fazer usar um esmalte desse!kkk Super hiper mega cintilante!! kk
Bom, esse acabamento e cor são os que mais me lembram minha mãe! Ela adora tanto rosa cintilante como lilás, no estilo do Zazá da Colorama, que ela teve uns cinco vidros (quando eram quadradinhos ainda!rs)
Apesar de não curtir esse estilo de esmalte esse foi tranquilo de cobrir, com duas camadas estava ok! Pena que marca um pouco o pincel. Fiquei feliz também por não ter lotado de bolinhas!rs
Não usei TC!
The Lofoten Islands have never looked more flat.
But that's for a good cause as it leaves some space for the sunset clouds that are trying to copy the earth slopes, only in reverse, sky style.
Me and my brother went on an adventure to find some abandoned WW2 tunnels and caves.. here's some collab shots we got on the way..
Harvest Moon over Rocky Hill, CT.
The clearest photo of the moon I've been able to take so far. All other attempts have cloud cover or the moon is tiny. The lighting around me must have been just right for the autofocus. I think if I'm well-lit, the moon comes out better than if it's dark around me. Taken at maximum zoom.
