| | | Milky Way
Has anyone actually successfully taken a photo of the milky way? Something like this? http://epod.usra.edu/archive/images/...yway_gross.jpg
I can't understand how such a photo could be taken  |

At first I was stunned that someone could take such a photo also, but I think the point in the reply above is that the picture is faked? Still, incredible detail  |

I know people who take genuine photos like that of the Milky Way.....
BUT - for a pic like that you need a very dark sky (no light-pollution) and a very long exposure.
So I think that the Milky Way pic, and the landscape in that pic were taken separately, then combined.
Either that, or ground and sky were processed separately, then re-combined.
But Milky Way pics like that CAN be taken with no more than a camera capable of long exposures, and a sidereal-tracking mount.
This was a straightforward 5 min exposure, taken from my mate's garden in Warrington. (You can see his satellite dish to the right)
It's the bright part of the Milky Way that goes through Cygnus - even caught a meteor streaking through the frame

I know that it is possible to use long exposure times to obtain images such as the one you have but I was only stating the fact that the finished article was not real. Hence the use of the word fake.

60 seconds would be enough...
There's a program called 'Registax' - free download, Google should find it.
Version 3 is best - V4 is newest but is very resource-hungry, and over-complicated for a new user.
You can take several 1 minute exposures of the same part of sky, then Registax will align and 'stack' those pics on top of each other, to build up the detail into one combined pic.
Registax can even stack hundreds of frames from an avi movie, to build up a more detailed jpg picture (a very popular planetary imaging technique)
Amazing what can be done with modern digital astrophotography techiques.

I will be sure to try it on the next clear night!
Where abouts in the milky way in the sky? Is it anywhere near orion? |

The Swan (constellation CYGNUS) flies down the milky way each night (so to speak  ).
Thats a good place to try and start locating it.
Hope that helps a bit...
