NGC 6300
Discovered (Jun 30, 1826) by James Dunlop
NGC 6301 (= IC 4643)
Discovered (Jun 11, 1788) by William Herschel (and later listed as NGC 6301)
Discovered (Oct 6, 1896) by Johann Palisa (and later listed as IC 4643)
A 13th-magnitude spiral galaxy (type Sc) in Hercules (RA 17 08 32.7, Dec +42 20 21)
NGC 6302 -- The Butterfly Nebula
Discovered (Jun 5, 1826) by James Dunlop (567)
A 10th-magnitude planetary nebula in Scorpius (RA 17 13 44.1, Dec -37 06 12)
The first IC notes "Seems to be Dunlop 567". The second IC adds "Planetary, 9th magnitude (Pickering). Drawing by Barnard, A.N. 4136".
Planetary nebulae are the shrouds cast off by red giants, before they collapse to become white dwarfs. In the case of the Butterfly Nebula (also less attractively known as the Bug Nebula) this must have been a recent event, as the white dwarf at its center (completely hidden by a dusty disc, seen edge-on at the center of the nebula) is exceptionally hot (approximately 250 thousand Kelvins, or more than 450 thousand Fahrenheit degrees). The Butterfly lies approximately 4000 light-years away. |

Discovered (1866) by Truman Safford (29) (and later listed as NGC 6347)
Discovered (Jun 6, 1866) by Truman Safford (and later listed as IC 1253)
A 14th-magnitude barred spiral galaxy (type SBb) in Hercules (RA 17 19 54.6, Dec +16 39 38)
(The NGC listing was originally credited to another observer, as Dreyer didn't notice Safford's reports until after the NGC was completed; but current practice is to credit the original discoverer, even when Dreyer credited someone else.)

NGC 6348 (= PGC 60036)
Discovered (Jun 29, 1880) by Édouard Stephan (11c-16)
A 14th-magnitude (barred?) spiral galaxy (type SBb?) in Hercules (RA 17 18 21.1, Dec +41 38 53)
Based on a recessional velocity of 9520 km/sec, NGC 6348 is about 445 million light years away. Given that and its apparent size of 0.6 by 0.5 arcmin, it is about 75 thousand light years across. Note: Every reference I've seen lists NGC 6348 as type Sb, but the image below shows a noticeable bar, hence my tentative listing of the galaxy as type SBb. |
