The 3towers Observatory:
Arp Galaxies 281-327 |
The following table of Arp Galaxies is based on the Arp taxonomy
in Dennis Webb Arp Galaxy page. These images were taken at
the 3towers Observatory located in Tucson, Arizona, using a
12-inch Meade LX 200 telescope working with a focal reducer at
f/6.5 and equipped with an Apogee KX260
CCD camera or with an Apogee AP7 camera.
The black & white exposures for the images vary
from single 60-second exposures to a combination of up to thirty
60-second exposures added together with a median routine. In
general, the images have not been processed except for bias and
dark subtraction, flat fielding, and contrast enhancement. They
were slightly cropped to show the objects of interest, and the
image width was set to 600 pixels. The image scales vary
slightly from image to image due to the differing degrees of
cropping. Nevertheless, it is possible to compare two different
images to observe the relative size of different Arp galaxies.
All images are oriented with the North at the top and the West
to the right.

NGC3788 is the
galaxy with the vertical orientation. NGC3786 is
oriented horizontally. The small, faint spiral galaxy
below and to the right of the two larger galaxies is

Arp316(NGC3193) is
the non-descript elliptical galaxy above and to the left
of the spiral galaxy (NGC3190) in the center of the
image. NGC3187 is the smaller spiral galaxy on the
right. These galaxies are, respectively, Hickson44B,
44A, and 44D. Hickson 44C (NGC3185) is not pictured,
lying south (below) the field of view. This is a
composite image of twenty 60-second exposures added
together. |
