Lovely set!

This is Camellia pollen viewed with reflected cross polarised light using a 50X objective with no coverslip - stacked in Zerene Stacker.

Very nice! I love the glass-like clarity you get on your images.

Great! It is remarkable how effective those cillia are and the velocity generated in the water, even at a distance from the heads.

Great work!

Thanks for the comments. It's a good service; occasionally the zoom is a little slow to come in to focus. The free hosting is limited to 250mb I think and each file is limited to 35mb. Here's another rock slice, around the same size but with larger granules. This is Eucrite from Ardnamurchan, Scotla...

A 30 micron section of Sillimanite - Mica schist from Aberdeenshire, Scotland. The section is 3cm x 2cm, photographed in transmitted and reflected polarized light together (hence the colour shift). It's a stitch of 72 images from a 2.5X MSPlan Objective. You can click on the image to go to a higher-...

Excellent!

Very beautiful. The first one reminds me of a van Gogh - must be the colours.

Stunning !

Thanks. In large part the quality of the hi-res image is testament to the skills of Mr. E. Ives, it’s not often you get such a perfectly flat, thin section. The combination of the staining and cross polarized lighting make it look a bit like a confocal image.

When do you start the human trials?

I think it would take well over 2000, maybe 3000, photos to get a whole image of the heart at 40X - without any stacking. The final jpg I produced after stitching 14 images of the plant stem was 22.7mb 11150 x 8831 pixels and the Zoomify files are 20mb I suspect a 40x stitch of the rat's heart would...

It’a very good point. Lots of stitching and stacking to post a final 300kb, 1024 x 800 image is rather a waste of effort. The full image of the heart is very nice but it would also be nice to be able to zoom in and see the amazing detail that the 40x objective captures. As download speeds get faster...

Thanks for the comments. Software like that would be a great way to catalogue important slide collections for access over the internet.
