Subject: Mars 14 Dec 2003
Hello everyone...
I have attached an image of
Mars taken December 14th. The image
leaves a lot to be desired from an image quality standpoint, but I believe that
it is of interest with the current dust activity.
The image was taken with a
25cm newtonian that I am
currently testing for planetary work, trying to avoid the focus changes that
occur with the IR and UV filters. This
image was taken at f44 using eyepiece
projection with the ToUcam Pro. The RGB
image was taken through a Schuler IRX filter, and the IR image was taken
thorough a Schuler IR83 filter. Each
frame is composited from approx 100 of the 800 frames
in a 30second video clip. Images were
stacked and processed with Registax2.
The images show a tiny SPC
and a bright area covering much of the centre of the disk, roughly south of Chryse to the Argyre area.
Is this some of the dust reported by others during the last week. There are few
other features visible, though I think Sinus Meridiani is visible along the
limb on the left side of the image. I would be interested in any comments on
the image that anyone would care to pass along (and corrections of any of the
above if necessary).
Thanks,
