After many item purchasing over a long period, it is the first time I quickly setup all the equipment !

Conditions:
Brief clearing, transparent and clear sky after much rain.
Location : Saint Remy les Chevreuse (35Km Paris, no major cities in the South)
Orion in the SW getting closer to the bright area of a street lighting (HP Na) :(

Technical details :
Had to hurry with setup, otherwise would have been perfectly ready but under the rain !
Polar alignment with polar viewfinder (3min)...ATTENTION Time must be entered in UT !!
Setting ISO 1600, JPEG mode
Rapid focusing only in the Canon viewfinder with confirmation by posing 10s and looking at APN screen x 10x (3min)
Orion framing (1 min)
Switching to RAW mode
Launching exposures of 1 min for 1 / 2 hour
Launching exposures of10s during a few min. NB: unfortunately already hazy skies.
No flat this time.

During disassembly and storage just before the return of the rain :
Canon 300D with cap placed on a chair outside under the open roof
(same temperature as during the shooting) ...
dark of 1 min (16)
dark 10s (13)
offsets to 1/4000s (5)

Image processing:

DeepSkyStacker (My first use ... I really liked it ! How easy !) :

Loading all images
The chronological display of RAW with direct exposure length allows note on a paper the different exposures / darks ...
Loading images, dark, offsets for the 1 min serie.
Elimination of images with manual shift clearly visible. 16 good RAW remain !
Processing with the recommended advices !
Adjustment and saving of the images after 15 minutes of fully automatic work !
Same procedure with 10s serie (unfortunately uneven because of the arrival of high clouds)
Saving in TIFF

Irfanview:
Lum color adjustment gamma etc . Saving PNG 16bits.

In Paint Shop Pro :
10s image in the background, 1min image above
Soft rubber to desaturate the trapeze
Subtraction of the pdark (see my page http://sweiller.free.fr/DSO-Canon10D-300D/DSOs-in-Polluted-Skies.htm)
Effects "photo processing"
Softening preserving the structure
Scaling and various savings.

Item used :

Orion 80ED
Mount LXD75
2 " tube extension
IDAS filter LPS
Defiltered Canon 300D
Pocket Shutter by Denis Joye
4GB CF card Ultra II High Speed Sandisk
DeepSkyStacker, Irfanview, Paint Shop Pro

Of course, it will be possible to do better with the same intruments next time with more time
of clear skies and better adjustments ( ISO 400, more RAWs, flats, etc.).

But anyhow I like the result in my rather polluted skies !
