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.

Arp282 is the galaxy pair near the left edge of the image. NGC160 is the prominent spiral galaxy to the right of center.
294 NGC3786;3788 ngc3786.jpg (17398 bytes) 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 NGC3793.

304 NGC1241+1242 Arp304.jpg (42936 bytes)  
316 NGC3193 Arp316.jpg (12747 bytes) 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.
