I found two (funny) entries in my logs.

12", 109x, NELM 7m5+ (Hakos/Namibia)
very bright and large but low surface brightness; 2:3 N-S elongated with large nucleus; faint, clockwise rotating spiral arms indicated through dark structures; NGC 6744A visible as a very faint but large structure 10' NW and looks like a part of one spiral arm

17", 182x, NELM 7m0+ (Hakos/Namibia)
very large; large N-S elongated bar-like nucleus; many stars and easy visible spiral structure; sketch cancelled because of to much details
