RA: 00h 38m 57.6s
DEC: +48° 20' 14"
Size: 8.0'x 7.0'
Magnitude: 9.3 (V); SB 13.7
Morphology: dSph/dE3; Sy2
The history of the galaxy started "as usual" in the 18th century when William Herschel discovered it in 1787. Interestingly he missed the neighbor galaxy NGC 147 which was discovered by his son John in 1829.
The better the technique, the more interesting became the structureless and faint galaxy. In the late 19th century Keeler was the first who photographed NGC 185 with the (today) famous 36-inch Crossley-Reflector. Nearly 50 years later Walter Baader [1944ApJ...100..147B] resolved the galaxy in individual stars through the 100-inch Hooker telescope at Mt. Wilson during a 4h exposure in 1943. Because of the similar magnitudes of the brightest stars he concluded NGC 185 as a satellite of the Andromeda Galaxy and so a new member of the Local Group. He also first describes dark clouds and two globular clusters. Ford, Jacoby and Jenner [1977ApJ...213...18F] later describes, listed and labelled in a nice finder chart 8 globular clusters after Hodge [1974PASP...86..289H] listed 5 GC's. Interestingly it is possible with HST today to resolve the globular cluster itself in individual stars.
Today we know that NGC 185 is the only known Seyfert II with an AGN in its center which is probably the cause of the dark structures near the nucleus. Its distance is around 2.2 MLy and so a little in front of the major Andromeda Galaxy with its 2.5 MLy.
Through a telescope NGC 185 should be visible from up to 4-inch. I listed my observation (only in German) in an observing project around the galaxies of the Local Group (http://www.deepsky-visuell.de/Projekte/Lokale_Gruppe.htm). Al (lamperti) stated a thread about the GC's in 2012 which I don't want to miss here (http://www.deepskyforum.com/showthread.php?190-Hodge-Globulars-in-NGC-185). All in all I could detect three globs with my 27-inch. The dark structure should also be visible in mid size telescopes. Frank Richardsen showed me the structure several years ago through his 20-inch. I revisit it with success with my 27-inch where it looks more like a hole. But now it is your turn.

As always, give it a go and let us know.
