The RNGC (Sulentic and Tifft 1973) notes that this is a 14.5 mag galaxy. Their coded description reads R,DIF,BM,*1'NP.
Paul Brown (1992, Webb Society Quarterly Journal, 89, 8-11, 'An Unlisted Galaxy in the NGC 6107 Galaxy Group') observing with a 10-inch f/5.5 and a 16-inch f/4.5 notes: "Using x80 and direct vision, NGC 6107 was seen as a substellar patch close south of a mag 8.9 star. At x260, a 45 arcseconds diffuse spot with a gradually brighter middle was revealed. There did not seem to be any distinct core or nucleus. At photographic mag 14.7 it was one of the brightest objects in the field, and I suspect that under moderately dark skies, a good 30cm telescope would suffice to see it."
