M 99 is one of the highlights of the Messier list in my opinion. I can add a 16" drawing from 2016. 220x (8mm Planetary), 15.5' field. m99_kisspeter.jpg m99_kisspeter_positive.jpg
I also have an older sketch with a 4.3". I really wanted to see the spiral but I think I didn't see it. Some irregularities but nothing more.
