拍摄的效果大家自己看看！

This image of the space shuttle Discovery (orbiter) has been taken from Northern France on April 20 th 2010 at 5:37UT, a few hours before its landing in Florida at the end of the STS-131 mission. What we see is the top of the orbiter with the payload bay door opened, and the sunlight comes from back left. Altitude 332 km (206 miles), distance to observer 343 km (213 miles), speed 7.6 km/s (4.7 miles/s), apparent speed at zenith 1.3°/s.The length of the orbiter at zenith represents 22 arcsec.With respect to this image, the orbiter flies from left to right , in order to slow down with its main engines before entering the atmosphere (after turnaround in the normal orientation, of course!)

Numerous details are recognizable: the elevons, the « NASA » logo on the left wing (angular diameter: 1.2 arcsec), the orbital maneuvering systems, the payload bay door opened (in four segments), the articulated arm (Canadarm/SRMS), the MPLM module (inside the bay), the airlock, the cockpit windows.

The instrument is a Meade ACF 10” telescope with Lumenera Skynyx L2-2 monochrome video camera (12-bit fits), focal length 4500mm.The mount is a Takahashi EM-400 specially modified to be controlled by joystick (see below).Processing: combination of 27 raw images, sharpening by wavelets, noise reduction. No other processing has been applied, in order to guarantee maximum realism and veracity of the details (see notes at the end of this page about image processing).
On the images below, taken on April 15 th and 16 th during the same mission, Discovery is docked to the ISS (center left) and seen from aft.A video sequence of the April 11 th passage will be constructed.

Below, the EM-400 mount modified for fast tracking.A digital control box (hooked on the left leg of the tripod) controls the mount while receiving the orders from the radio double joystick (one for right ascension, the other for declination). When this box is not connected or is off, the mount behaves as a standard EM-400.Tracking is performed visually with the help of a finder with cross-hair reticle, and a green laser helps for the initial directing towards the space ship. Design and manufacturing of this electronic modification (more tricky than expected) are the work of Emmanuel Rietsch (photo on the right, contact: emmanuel.rietsch@sfr.fr ): without him, these images could not have been made!Despite this performing tracking system, keeping the space ship inside a sensor of a few millimeters at a focal length of 4500mm needs a lot of concentration and training.An evolution towards autoguiding with a second camera, in substitution for visual tracking, is under study.
