On a second occassion he called it "vF, S, R, 2 vS stars near." His third observation was recorded as "F, R, gbM." The final observation was recorded as "pF, lE, gbM, either resolvable or has loose stars."

Steve Coe, in "SACNEWS On-line for October 1996" notes: NGC 7221 is very faint, pretty small and round with a somewhat brighter middle at 100X. This galaxy has a very low surface brightness (13.3 mag) and higher powers makes it extremely tough to see. It is at 22 hr 11.3 min and -30 37.
Steve Coe, observing with a 13" f/5.6, notes: "Very faint, pretty small and round with a somewhat brighter middle at 100X. This galaxy has a very low surface brightness and higher powers makes it extremely tough to see."
