144P/Kushida
This image is a combination of two different methods,
photographing with tele lens and mirror. The
original image
is taken with a Audine Kaf 3200 ME ccd camera,
settled on a 300
mm tele lens, f-4 at 2008-12-17.
The inlay image in the middle is taken with a ST10XME ccd camera and the same chip, settled on
a 12" SCT f-7 telescope at 2008-12-19.
The inlay image
above is taken with the Audine camera and the tele lens of Stéphane Takbou again
at 2008-12-21.

When I prepared the
image with Adobe Photoshop I remarked a curve in the comets path. After checking
the path in TheSky
everything was clear:
The line is representing the path of the comet during four days, starting at December 17 and ending at December 21.
