Auliscus oaramuensis from Oamaru, New Zealand. Two examples on the slide. Prepared by WA Firth. Olympus BHB using 450nm LED light. 63x Leitz Pl Apo NA 1.40 objective, oil immersion. Olympus Aplanat Achromat condenser, oil immersion, slightly oblique lighting. 2.5x Nikon CF PL photoeyepiece. Monochrome converted Nikon d850 camera. 46 images stacked in Zerene (Pmax). These looks to have been mounted with the underside of the diatom facing the coverslip so the image shows the view of the underside of the diatom.
