18 Image Gallery with Canon 350D Hutech type 1 filter mod
June 17, 2005
October 18, December 2
Field of view
is 1 x 2/3 degree with C-18
images were acake walk and actually twice as many
other objects were captured that night (June 15) waiting for the
moon to move and then after it set (those images are not shown
yet). The camera is supported by Maxim DL and run via PC. It has
a very small footprint, huge chip and nice resolution, very well
matched to the C-18. Haven't even done flat fields yet! One could
say that " the cat is out of the bag", but "THE
BULL IS OUT OF THE PEN!" is more appropriate. Stay tuned.......
NEW: Lower set of 9 taken
at Norma Rose Observatory Queensland Australia winter 2005. All
unguided, dark subtracted, and flat fielded. Click on label for
lager version. Note: some purists may notice unsymmetrical bright
star patterns at either the top or bottom edge of the frames.
This is due to the camera's internal mirror assembly protruding
against the chip which gets in the way of an f/2.8 light cone.
While flat fielding fixes the illumination issue, it can't fix
the diffraction effect from this.
