telescope. Arne made the images on May 20-24, 2004 using BVR
filters. Al composited B=blue, V=green, and R=red and created the
luminance layer from a stack of all images.
L/CMY color composite, hydrogen alpha (Ha -- 6563 angstroms)
image, and overlay comparison image of galaxy NGC 2903 in Leo,
processed by Al Kelly from Ha-filtered and continuum-filtered
exposures taken by Arne Henden of the US Naval Observatory in
Flagstaff, AZ and CMY-filtered integrations taken by Al Kelly at
Ft. McKavett, TX. Arne made 2 images, one with an Ha filter and
one filtered for a nearby continuum region, using the 1.0-meter
USNO telescope and a 1024x1024 SITe-chip CCD camera. The CMY
images were made with an 8" SCT and a Cookbook 245 CCD
camera. Arne's images were summed and processed to create the
luminance layer for the L/CMY composite and were used to create
the difference image for the Ha representation.
WCMY image of spiral galaxy M101 made by Al Kelly on 4/17/99 from
Ft. McKavett, Texas using a CB245 and a C-8 telecompressed to
f5.6. Twenty 60- second subexposures in cyan, twelve 60-second
subexposures in magenta, and twelve 60-second subexposures in
yellow were combined with thirty 60-second subexposures in white
(IR-filtered only).
Image of beautiful barred spiral galaxy NGC1300 taken on 11/9/96 by Ed Grafton with his C-14 and ST-6 CCD camera from Clear Lake City, Texas.
Tricolor image of galaxy NGC 253 by Al Kelly, taken on 11/3/96 with CB245 and C-8 (at f5.6) from Friendswood, Texas. 11 minutes of red, 17.5 minutes of green, and 22 minutes of blue were composited using Richard Berry's color245 software.
False color image of elegant galaxy NGC 772 . Original image by Ed Grafton, taken on 11/2/96 with his ST-6 and C-14 from Clear Lake City, Texas.
Image of two-armed spiral galaxy NGC7479 by Ed Grafton, taken on 8/20/96 with his C-14 and ST-6 CCD camera from Clear Lake City, Texas. This is a 48-minute composite exposure.
Tricolor image of central part of galaxy NGC 253 by Al Kelly, taken on 9/14/96 with CB245 and 32" f4 Newtonian from Danciger, Texas. 2 minutes of red, 2.5 minutes of green, and 3.75 minutes of blue.
Image of barred-spiral galaxy NGC5921 taken on 7/13/96 by Al Kelly with 32" f4 Newtonian and CB245 CCD camera from Danciger, Texas. This is a 7.5-minute composite exposure.
Image of Spiral Galaxy NGC3953 by Ed Grafton, taken on 3/3/96 with his ST-6 and C-14 from the middle of Clear Lake City (a suburb of Houston with a 2.5-magnitude sky!)
Image of Spiral galaxy NGC 4535 taken on 3/9/96 by Al Kelly with 32" f4 Newtonian and CB245 CCD camera from Danciger, Texas. This is a 3.5-minute composite exposure.
Image of "Hoag's Object," a distant ring galaxy (PGC 54559) imaged on 6/15/96 by Al Kelly with 32" f4 Newtonian and CB245 CCD camera from Danciger, Texas. This is an eleven-minute composite exposure which has been processed with a mild unsharp mask to bring out the faint spoke-like structure within the ring.
Image of Disrupted galaxy M82 on 6/8/96 by Al Kelly with 32" f4 Newtonian and CB245 CCD -- 3 minutes from Danciger, Texas
Image of Galaxy NGC4504 imaged on 6/15/96 by Al Kelly with 32" f4 Newtonian and CB245 -- 5 minutes from Danciger, Texas
Image of Galaxy cluster Abell 2218 by Al Kelly, taken on 5/24/96 with 32" f4 Newtonian and CB245 CCD camera from Danciger, Texas. This is a 21-minute exposure (eighty-four 15-second images) showing about ten foreground stars and dozens of distant galaxies. This cluster was imaged by the Hubble Space Telesope in 1995 as part of a study of the affect of gravitational lensing. See the July, 1995 issue of Sky and Telescope Magazine, page 11, to see the gravitational lens arcs in Abell 2218
Closeup image of the center of Abell 2218 , as captured in the above image on 5/24/96. The arrows point to smudges of light which come from the very distant galaxies which have been brought into "focus" by the gravity of Abell 2218. There are few other amateur photographs of gravitationally lensed objects.
