First calibration shots of new ed80. Only 89 x 20 sec sub frames ( before the clouds rolled ) in of the clouds within m31.Pinpoint stars and lovely cloud detail has demonstrated the ed80 to be an excellant widefield imager. More to come!

Test image through a 135mm canon FD lens. I had to half close the iris as the stars get pinched when using full aperture. I don't think the lens was designed for astrophotography!

Upon closer examination there is an object passing through the field of view with a smaller sister object next to it. It is definately not a hot pixel, nor a satellite in geostationary orbit . I am yet to identify this & cannot see any matching objects in the latest MPCORB.DAT files , nor the Minor Planet Checker databases. The initial frame was taken at 23:56 on the 26/10/2006 UT with the final 60th frame completed at 01:58 on the 27/10/2006 UT, each frame being 120 secs in length.


This is an average stacked shot, displaying the path the object has taken.


Initial astrometry puts the larger of the two objects at mag +19 and the companion object at +21 For those interested , the first and last raw frames are here


Ra , Dec, astrometry & photometry of the objects ( no. 16 and 17 ) can be found at this screenshot here .
