Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB, pS, E sp-nf, vgmbM."
In the 5th edition of Webb's Celestial Objects for Common Telescopes it is mentioned in the description of M13: ". . . The neighbourhood [of M13] is beautiful with a low power. A faint nebula [NGC 6207] about 40' N.f."
Photo Index by Jim Lucyk: Sky&Tel. 9/82 p292 (also visible IC 4615, Sky&Tel. 11/76 p395 (IC 4615), Deep Sky #3 Su83 p16.
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads EL,BM,HISB.
Houston notes that this small 3' long spiral is located just 40 arcminutes northeast of M13. "Although brighter than 12th magnitude, it's an easy target for my 4-inch Clark refractor on a good night . . . under good skies a 6-inch should easily snare this 11th mag spiral. Large apertures may show what appears to be a bright nucleus, but it is really a faint foreground star superimposed on the galaxy. If you can see this star, try looking for the very faint galaxy IC 4617."
Michael Sweetman (Tucson, Arizona, USA) observing with a 6-inch refractor, writes in the The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: " ... nearby [M13, the ] galaxy NGC 6207, shows as a small, faint smudge of light to the N.f. side of the field."

Telescope: Meade 8" 18mm eyepiece, 36 arcmin f.o.v.
Date: August 1998.
Sky conditions: Not very good.
Description: Could not find it - only a few bright stars in a bare starfield.
Alldays (22.50S, 20.12E, 770m).

Like most galaxies it shines like a soft cloud, somewhat brighter to the middle. Elongated in a southwest to northeast direction. NGC 6207 is a lovely elongated haze N-S. Lies about ½° east-northeast of M13
