2008/10/11_ISS-Quest Airlock observation
Observation of the ISS Quest Airlock,the place were Astronauts leave the spacestation for a spacewalk.This is an enlargement of the best frame in an earlier image.Note that the Quest looks more elongated then it actually is due to shade effects probably.That means it is actually wider then the image suggest.
The following pictures may also give answer to a question which is asked me many times:
could we see astronauts in theory:

Wow Ralf this is to much for me, I'm going to pass out !
You're really nailed it this time !
Just keep them coming !
Indeed when you get an astronaut making his space walk that should be incredable unbelievable imposible .....can't find words anymore

Hello, Ralph
I’ve enjoyed all your images of the Shuttle and various components and you never cease to amaze and inspire me with your work.
If anyone can image an astronaut outside the station, I’m sure it would be you, so good luck!
Cheers
Dennis

Very interesting, Ralph. I would say given your image, if the lighting angle was right, you might be able to see a spacewalk.

Hi Hutch,
Yes,but it still will be very difficult.Like you already said,very important is the right lightning and observing anlge.There is also a lot of shade around there.We will need all the luck possible...

Luck, the chance convergence of preparedness with opportunity. 'good luck' normally includes a little 'help' to reduce the amount of 'chance' in the convergence.
Your photos of the ISS are superb, and there's lots of folks all over that watch your updates with huge interest. There's got to be a lot of folks at NASA that watch your work, and grin when they see it.
There are a LOT of factors that go into the scheduling of a spacewalk, most of them technical. BUT, if the window of opportunity is such, it's plausible for them to delay an event a few minutes, to put it dead overhead you on that day the spacewalk is going to happen, the thought will never occur to anybody, if you haven't asked.
It certainly cant hurt to ask, and, there's an off chance it may actually affect scheduling some day by a few minutes. A ground shot by an amateur, of the astronaut shortly after airlock exit, has got to have significant PR value for the folks involved. A simple note to ask for scheduling consideration cannot hurt, and you never know, it may very well dramatically reduce the chance component involved in 'good luck', that random convergence of opportunity and preparedness.
