Comet NEAT Q4/2001 on May 16, 2004
Location:
Texas Star Party 2004 near Ft. Davis, Texas Date:
May 16, 2004 Seeing:
8/10 Transparency: 9/10 Scope/mount: Tak
FSQ-106 @ f/5 with Tak NJP mount Camera: SBIG
STL-6303E NABG with integrated filter wheel Exposure Info: Grayscale,
one minute exposure Processing: MaxIm
DL 4 (Image acquisition and digital development). Photoshop CS (Levels,
Curves).
Other info: Yes,
a single one minute exposure! Nothing beats
dark skies! Because this shot gave the depth I
was looking for, I decided not to add additional exposures
since the comet moved too much during this time. I
would have added color information, but this was first
light with the new SBIG STL-6303E and I didn't have
the filter wheel setup correctly.
This comet was
found by the Near Earth Asteroid Tracking program (NEAT) in
2001. What follows is a series of photographs
showing it's progress toward our northern skies. Early
estimates of this comet were for it to appear as a magnitude
1 comet in early May and slowly dim as it climbs the
sky toward the north. The projections were a bit
optimistic as the comet topped out around magnitude
3 and the tail hasn't shown itself to be all that
extended as the images below demonstrate. But
it's still a beautiful site!
Comet NEAT Q4/2001 on May 9, 2004
Location:
Ballauer Observatory near Azle, Texas Seeing:
4/10 Transparency: 3/10 Equipment: Canon
Digital Rebel on tripod with 15-55mm lens Date:
May 9, 2004 Exposure Info: 13 x 25 second exposures Processing: Images
Plus (align and combine), Photoshop CS (Curves, blending
of last exposure in "lighten" mode)
Other info: In
order to bring out and stabilize the foreground because
of the moving stars, I opened the last image of the
stack and copied and pasted it as a new layer in Photoshop
over the entire stack. I then chose "lighten"
for the blending mode. The result keeps the star
images the same while improving the foreground.
