    Canon EOS 450D + Samyang 1.4/85mm, 800 ISO + ASTRORECORD astrometric
    software.
    What these numbers mean: http://www.satobs.org/position/IODformat.html
    -------------------------------------------------------------------------
    
    
    Nice clear sky allowed to target geostationary objects. I need clear transparent 
    sky for that, as for me they are at 15-30 degrees elevation only, in an urban 
    environment.
    
    I used the 1.4/85 mm lens this time instead of the 2.8/180mm. The limiting 
    magnitude is almost as good, and the FOV is twice as large (14 x 10 degrees). 
    The result: lots of objects in one image (up to 20 objects in one image!). The 
    downside: lots of objects to ID and measure.....took me a full day.
    
    Above are 8 classified objects and 30 non-classified objects, located along an 
    approx. 30 degrees equatorial stretch... Non-classifieds were measured only 
    once, and I did not measure LEO strays seen.
    
    NOTES:
    
    The object called PAN above is the object discovered by Greg, located somewhat 
    east of Hellas-sat 2 and about similar brightness.
    
    The DSP F20 cover initially appeared to me as a slowly moving UNID, as Heavensat 
    depicted nothing on the location, but Ted's IDsat identified the object as such, 
    albeit with a clear and non-linear delta-T so it should better be checked 
    whether the ID is correct..
    
    The DSCS3-13 R2 was somewhat off as well, but elements were old.
    
    Also, my first obs of a DSP satellite.
