So all done using x100, na 1.25 oil and canon 1200D.
Zerine stacker and (where relevent) microscoft ICE for stitching.
I use GIMP to post process and I tend to clean, tweek levels and sharpen up a little.
2 Stacks of 10 Thalassiosira oestrupii (I think) (about 100 microns)

Stack of 5 Auliscus sculptus (likewise) (About 70 microns)

Triceratium antediluvianum. 120 microns 3 stacks of about 15.

Thalassiosira baltica but happy to be corrected. 3 stacks of about 15.
About 140 microns.

Not sure what this one is. Used a yellow filter hence black and white.
Big boy, about 200 microns. Pain in the backside to stitch
