Overview: NGC 7606 is a a spiral galaxy located in the direction of the constellation Aquarius the “water-carrier.” The constellation likely dates to ancient Babylon whose god Ea is often seen as a star-figure holding an overflowing vase or cup. NGC 7606 is about 100 ± 20 million light years from Earth which yields a size of about 165,000 light years across or about 65% larger than our own milky way galaxy. It is moving over 2000 kilometers per second away from earth.
Details: NGC 7606 was discovered and cataloged by William Herschel on September 28, 1785 and is a fairly typical non-barred spiral galaxy as seen inclined. If it were seen face-on it would form a circular image, but like a dinner plate tilted toward us, it appears oval or elliptical in shape. It does not have a bar connecting its arms, but it does have an inner right partially visible here in the inset.

The galaxy has two separate galactic arms that extend completely around its nucleus 1-2 times. Like most spiral galaxies it’s center nucleus does contain a supermassive black hole of some 20 million solar masses (1 solar mass = mass of our sun).

Annotations. The above image shows annotations when hovering over the image. The galactic nucleus is clearly visible and enlarged here and the galactic ring that partially envelops the central bulge is clearly visible. Also shown is an enlarged inset of the 17.2 magnitude galaxy PGC 1003486 which appears to be a barred spiral or a significantly disturbed spiral galaxy and over 30,000 times fainter than the faintest star visible to the naked eye.

Below Images: In the first image below, the same image has been processed to remove all foreground stars as these stars are all within our own Galaxy. This is what the view would appear like if we left our galaxy looking outward. Using a mouse to hover over the image comma brings all of the stars back. The second image below shows an enlarged and cropped versions of the galaxy.
