Albert Marth discovered NGC 6971 = m 425 on 15 Aug 1863 and noted "vF, S, R." His position is accurate to within 1'.
400/500mm - 17.5" (8/1/86): fairly faint, moderately large, pretty diffuse, weak concentration, slightly elongated WSW-ENE. Located 7.1' SE of mag 7.7 SAO 126248. This bright star is at the midpoint of two nearby mag 9/10 stars on a line WNW-ESE.
600/800mm - 24" (9/5/18): at 225x; fairly faint, fairly small, roundish, 35"-40" diameter, fairly low surface brightness. Contains a slightly brighter nucleus that rises slightly to a faint stellar peak. This galaxy was a bit fainter than expected. Located in a pretty rich star field 7.2' SE of mag 7.7 HD 198271 and 24' E of mag 5.6 13 Delphini.
UGC 11639, located 15' NNE, appeared fairly faint, round, 35" diameter, faint stellar nucleus. Very similar (or perhaps marginally brighter) than NGC 6971.
