The 3towers Observatory:
Arp Galaxies 103-169


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.
