Spiral Galaxy NGC 3389

Spiral Galaxy NGC 3389; CCD image thru 20 inch

This is a 30 minute exposure with an STL-1301E CCD camera thru Kopernik's 20-inch F/8.1 Ritchey Chretien Cassegrain telescope.

Spiral Galaxy NGC 3389 is a part of a trio of galaxies that include Elliptical Galaxy NGC 3379 (M-105), and Lenticular Galaxy NGC 3384. All of these are a part of the Leo galaxy group. All three fit in a single eyepiece field with a 10 inch telescope. However, NGC 3389 is difficult to see in any telescope much smaller than a 10 inch.

Dreyer's description from the New General Catalog(NGC): Faint, large, extended east-west, very gradually little brighter middle, 3rd of 3 (galaxies).
