Machholz C/2004 Q2
Composite image obtained
combining exposures through the filters B, V, and R
(exposure times were 8 sec, 3 sec, and 2 sec, respectively) acquired by
myself and S. Ciroi (Univ. Padova) on 2005 Jan. 7th, with the Asiago
Faint Object Spectrograph and Camera (AFOSC) mounted on the Copernico
1.82 m telescope of the Astrophysical Observatory of Asiago (Italy).
A photometric calibration has been applied to the fully reduced images
before combining them.
The composite image was created with The Gimp.
