Fall '07 Astro 9A/B/C Student Photo
we were graced with pretty good weather, an good group, and Comet Holmes - the
brightest dark-sky comet in a decade.
Open Cluster M11 in Scutum. Sept
I shot this one. 11 seconds only! A simple 'grab' with the ST2000XCM
on the 10" LX200 alt/az mounted. Very low signal/noise doctored
with Photoshop levels, enhanced saturation, AstroTools 3x 'make stars
smaller', 'space noise reduction'. Basically, a first test of the alt/az
for shooting clusters.
Gamma Cygni Nebula Oct 4.
Fred shot this 3x5 stack of
the Gamma Cygni nebular region from Cabrillo Observatory. Heavy processing
in Photoshop CS2 brought out the faint nebula against the light pollution
M27 The Dumbell Nebula
- Nov 14. Fred
shot this 3x5min stack from Cabrillo under a cresent moon and with the
nebula into the west, over the lights of Santa Cruz. The nebula is small
and so there's lots of cropping here. Nice!
- Oct 10. Abbey
took this 2x5min stack while the cluster barely cleared the redwoods
on the ridge. Low altitude and poor seeing made for big stars. The color
was re-balanced to de-redden it.
The Double Cluster in Perseus,
Oct 10. Jimmy
took this 5 minute shot of the brightest star cluster in the Fall sky.
The red giants stand out from the blue main sequence stars nicely. No
The Dumbell Nebula
Oct 3 - Tyler's 3x5min
stack on a perfect night with good seeing; important since its pretty
small for our image scale.
The Veil Nebula, Oct
10 - A tough challenge
for Sakaya in Cabrillo's bright skies. This 3x5min stack had the sky
brightness almost at the level of the nebula, hence the darkness of
the final image.
Everyone got a chance to frame and photo the moon on Sept 20 through
the 8" Meade scope. A snapshot of course, even for the ST2000XCM. Not guiding
necessary, but the scope was roughly polar aligned and turned on.
The Moon. I
did this one, an experiemental canvas for exploring what Photoshop can
do. I tried lots; including the shadow/highlight adjustment for the
first time. The seeing was poor and the moon low in the sky, so I did
a ton of variants of 'sharpen'.
Comet Holmes - Fred
Miles' stacked this set. Good balance of light and dark areas.
The Orion Nebula - Fred
got this shot of the Orion Nebula just after it rose above the Hort
building and trees. Careful processing made for a remarkable result
The Moon - Fred's
version of the first quarter moon. Very nice!
