NGC 3500 (= PGC 33277)
Discovered (Apr 2, 1801) by William Herschel
A 14th-magnitude spiral galaxy (type Sab) in Draco (RA 11 01 52, Dec +75 12 05)
Based on recessional velocity of 7400 km/sec, about 330 million light years away (although another recessional velocity measurement of 3465 km/sec would yield only half (!) that distance). Considered to be a member of the NGC 3523 group of galaxies, in which case the 7000+ km/sec recessional velocity for the other two galaxies suggests that the larger recessional velocity and distance are more accurate. Given that and apparent size of 1.3 by 0.6 arcmins, about 120 thousand light years in diameter. Note: Wikisky incorrectly shows NGC 3465 if NGC 3500 is entered. However, using the PGC 33277 designation shows the correct object.

NGC 3501 (= PGC 33343)
Discovered (Apr 23, 1881) by Édouard Stephan (11-10)
A 13th-magnitude spiral galaxy (type Scd) in Leo (RA 11 02 47, Dec +17 59 22)
An edge-on spiral galaxy, paired with NGC 3507. Based on recessional velocity of 1130 km/sec, about 50 million light years away, in fair agreement with redshift-independent distance estimates of 65 to 85 million light years. Given that and apparent size of 4.4 by 0.55 arcmins, about 65 thousand light years in diameter. |

Discovered (Mar 14, 1784) by William Herschel
A 13th-magnitude barred spiral galaxy (type SB(s)b) in Leo (RA 11 03 25, Dec +18 08 08)
A face-on barred spiral, paired with NGC 3501. Based on recessional velocity of 980 km/sec, about 45 million light years away, in fair agreement with a redshift-independent distance estimate of 65 million light years. Given that and apparent size of 3.4 by 2.9 arcmins, about 45 thousand light years in diameter. |

NGC 3508 (= NGC 3505 = IC 2622)
Discovered (Dec 31, 1785) by William Herschel (and later listed as NGC 3508)
Discovered (May 7, 1836) by John Herschel (and later listed as NGC 3505)
Discovered (Jan 14, 1898) by Lewis Swift (and later listed as IC 2622)
The second IC adds (per Howe) "is small, and the star half an arcmin northeast is not involved".

NGC 3509

NGC 3510
Discovered (Apr 11, 1785) by William Herschel
NGC 3511
Discovered (Dec 21, 1786) by William Herschel
The second IC adds "= V.39. Not found by Innes, while 3513 = V.40 (same description) was well seen (M.N., lix. p. 339)". (The statement = V.39 (William Herschel's list V#39) seems odd, as it was listed as such in the original NGC, and usually such a note would represent a correction.)
