The backbone of the ISS is complete now with the attachement of the new S6 truss segment
which was carried to the station by the spaceshuttle Discovery at STS-119.
Already visible in this view from March 20 are the fully deployed S6 solar arrays.The deployment
was completed just a few hours before the pass.
Also as sign of the S6 truss element itself is visible.Images will in future certainly show nicer views of
the solar arrays,the position to the observer wasn't optimal in this image.Also I chose for
a frame showing als the shuttle with open payload bay doors clearly.Another nice detail is
the Canadarm 2.
Imaging details as always: 10inch Newtonian manually tracked using a 6x30 viewfinder.
Here is a stack of 6 good frames I managed to capture at
the observation as mentioned below.Note that this is an approach image,the distance
was still considerable.Still are details visible within the Robotic Arm Candarm 2.
The Spaceshuttle Discovery is very well recognizable.
This is my first observation which shows actually clearly the Canadian shuttle Robotic Arm
(Canadarm 1 or Shuttle Remote Manipulator System (SRMS).What makes the image
especially wonderful is the view of both the shuttle arm and the station's main arm
(Canadarm 2 or Mobile Servicing System (MSS)together after a hand-over operation
of the S6 truss segment with the new Solar Panels one day earlier.The shuttle arm(SRMS)
was used for filming and documenting the deployment of the new solar arrays a few
hours ealier and can be seen still in this position on the photo.

_________________________________________________
A reprocessing using a composite of 10 frames taken during
approach of the docked Space Shuttle Discovery on STS-119 mission
in March 2009, resolved some surprising detail including a
sign of the Main Engines(SSMEs)of the Orbiter.
For a visualisation model to compare, see:

There is a special difficulty capturing the engines due to
problems with the lighting and position angle of observing.
Although resolving them is theoretically within the reach of
an amateur telescope, the engines are not optimal lighted by
sun during culmination, the position were we have shortest
distance and so best resolution. A while before culm, during
approach, lighting angle is better, but resolution is far
from optimal. In this case, thanks to exellent seeing and the
luck with 10 usable frames to improve slightly sign/noise ratio,
it succeeded however.

ISS with STS-119 and new S6 solar panel
It's been a week but I finally got around to processing these images. On the
mornings of Friday 20th and Sunday 22nd March I had a few bright passes of
the International Space Station (ISS) over my location. The great thing was
that the Space Shuttle Discovery (STS-119) was docked at the time so I was
hoping for good seeing and hoping I'd be able to track it accurately. I was
able to capture reasonably detailed images during both passes, but of course
you always want more. For the image on the 20th, my shutter speed was a
little too slow so the frames were a bit soft. The lighting and angle meant
the backside of the shuttle was facing us and was not illuminated and could
not be resolved. The image from the 22nd shows a lot of detail and structure
in the radiators and also includes the new S6 solar panel that was installed
by the STS-119 crew on the 21st March. Space Shuttle Discovery is barely
visible - only it's tail is illuminated and was just about the noise level.
