(Left) First ever attempt at star trail pictures, exposure times 6 and 18 minutes,
respectively. Taken with a
Canon 350D DSLR
with an
EF-S lens at 18mm,
f/9.0. Noise reduction and bad pixels removed in second image.
(Right)
Single 1/160 second exposure of the moon with an
EF lens at 300mm, f/5.6. Sharpened and
level adjusted.
(Left) Image of Vega with exposure time of 0.66 seconds. Scaled to
look cool.
(Center) Single 1/500 second exposure of the moon with the
Canon 350D, EF lens at 300mm, f/5.6. Color balanced to white and
sharpened.
(Right) First stellar imaging attempt, 1 second exposure of
Orion's Belt area, EF lens at 300mm, f/7.1. Unguided tripod shot - maximum
exposure time at this zoom before rotation became evident.
(Left) Image taken with a
Canon 350D attached
at prime focus to a
Meade LX200GPS 14"
Schmidt-Cassegrain telescope, 3556mm at f/10. One 5-second dark-subtracted
exposure composited with one non dark-subtracted 30-second exposure. Guided
exposures on an alt-az mount without any field derotation. Ambient temp
39°F. Focusing and seeing issues.
(Center) Composite 8x10s (ISO
800) with
un-modified
Canon 400D attached at prime to the
Meade LX200GPS 14",
unguided, no field derotation. Dark-subtracted from a 8x10s master. Median
added, noise reduction and levels in
Photoshop. Focus FWHM ~6-8px at
10MP. Outside temperature 44°F, seeing 3/5, transparency
2/5.
(Right) Same data, less selective on sub-exposures, leading to
18x10s composite, for 3 minutes total integration time.
(Left) 16x30s at ISO 1600 with
the
Canon 400D on
the
Meade LX200GPS 14",
unguided, no field derotation. Dark-subtracted from a 16x30s master,
converted to RGB and median stacked in
MaxIM DL. Noise reduction and levels in
Photoshop. Seeing 3/5, transparency 4/5.
(Center) Attempt at star trails, taken from Mokule'ia Beach, North Shore of O'ahu, Hawaii, with Waialua in the foreground. 125x30s composite for a total of 62.5min. 17mm f/4 at ISO 400 with the
EF-S 17-85mm f4-5.6 IS USM.
(Right) Single 30sec exposure from sub-mm valley on Mauna Kea, Hawaii. Looking towards Keck I with the LGS-AO system active. Subaru in the foreground.
(Left) First actual attempt at imaging
NGC2024. Composite of 49
individual images. Ks (red), J (green), and H (blue) bands at 10, 30, and 30 seconds per exposure,
respectively.
(Center) S106 at Ks only, scaled on a custom shifted
red-temperature scale.
(Right) Identical data as before, with
logarithmic color mapping and post-processing to set the black point. Final
image for the Oct 29 data of NGC2024. All three images taken with
IRCAM on the
Leuschner telescope.
"Goal" images which I attempt for in the pretty pictures category.
(Left) NGC2024 from Reipurth.
(Right) S106 from NAOJ's
Subaru telescope. Both images have a FOV of
approximately 5'.
