This fungus was growing on the earth around the base of the plant in a plant pot in our kitchen in Lichfield. Interconnecting hypae can be seen but the stand-out difference between these photos and those of fungus on bread and cheese I have posted in past is the lack of spores.

The following two photos show structures on edge of an algal strand from my pot pond – not sure if these are part of algae or other organisms which are using it as a platform to base themselves….

About a month ago, I placed a slide in my pot pond outside and the algae on the photos below are those that have grown in situ. The slide was in the top ten centimetres of the pot pond – where sunlight would hit the slide every day.
This has also been an opportunity to try out my QHY6 mono astronomical camera on my Zeiss IM microscope & compare photos taken with that camera with those taken with my trusty Bresser Mikrocam SP 5.1 camera – the main issue is the small sensor on the QHY6 gives highly magnified image & loss of detail as in monochrome.

For last few months, I have been cultivating a “pond” in a large pot in my garden.
The following photos are taken from a sample from the bottom of this pond today, using my Leitz Laborlux 11 microscope and Bresser Microcam SP 5.1 camera, with x4, x10, x40 objectives.
The photos and video below are all based around highly magnified microscopy of the antennae/legs of a small 2-3mm crustacean I found in the sample. In particular, I focus on other animal life (single and multicellular) living on or around these structures.
Obj = microscope objective power.

See the small group of oval objects attached to the antenna on the right – I think this is a group of other organisms using the crustacean as a platform!
On the other two legs visible, note the nodular structure to the chiton exoskeleton. Plenty of hairs to be seen projecting from legs and antenna.
Those group of oval organisms are seen attached to the antenna at bottom of photo below (photo & video):

Elodea is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Elodea is native to North and South America and is also widely used as aquarium vegetation. It lives in fresh water (Wikipedia). Chloroplasts can move in all plants but are particularly visible in Elodea.
I used my Leitz Laborlux 11 microscope today to view a thin slice of Elodea leaf with a bright light from the side to stimulate movement.

We dissected a sheep’s head today and prepared simple slides of brain, retina and optic nerve, and then viewed these with my Leitz Laborlux 11 microscope using x4, x10, and x40 objectives.

Dissecting sheep’s head:
The brain of the sheep can be seen just before removal.
Brain unstained slides, x4 objective:
The red streaks are blood vessels – note these are all unstinted sections.
Brain unstained x10 objective:
These sections were all made by using scalpel to cut thin section by eye and then squashing it on slide with some water based mountant using a cover slip. They are therefore quite thick.

Optic nerve, unstained, x4 objective:

Optic nerve, unstained, x40 objective:
In the section below, looks as though an axon (projection from a nerve) has been pulled out – long worm-like structure.
Likewise, in the slide below, there appear to multiple coiled structures which I suspect are axons.
Retina, unstained, x4 objective (below):
Retina, unstained, x10 objective:
There appears to cells on stalks – are these neural connections to retinal cells?
Note the heavy pigment of the retina – black – it absorbs all light.
