this is a beatiful Paramecia bursaria I found in a stream sample. It is so big, that I saw it even on my stereo magnifier @40x. It was pretty hard to isolate it and track it down. Eventually I lost it:) Nikon CFN Planapo 60 0.95 160/0.11-0.23 / no eyepiece camera: Nikon D3400 (no camera lens) PZO Pluta DIC on Zeiss Winkel GF
