Re: The wisest way to buy a microscope
Love it when spammers get backed into a corner. They get all hissy like a cat caught stealing the Sunday roast :D I own an Apex badged Chinascope model that is still being sold under various brands in the £400-500 bracket. That had a QC sticker on it, the mains earth wire wasn't even connected. It's...

Definitely not normal, and if that passed QC it says a lot about the manufacturer..

To me it looks like a chlamydospore sack, common to some species of fungal mycelia.

Re: Cleaning slides lifehack
I 3D printed a holder for 10 slides + covers that fits into a small 850ml 35w ultrasonic cleaner. One 8min run in dilute detergent (biological washer liquid), rinse under warm tap, spray rinse with distilled water then stand to dry. Best method I've found thus far that doesn't involve solvents etc. ...

Re: Pond Life!
Nice work Louise, keep at it. The filaments with the granules look like Beggiatoa, a filamentous proteobacteria. The granule density varies somewhat and is likely to be sulphur. They use inorganic elements to synthesise carbohydrates, and sulphur is plentiful in semi stagnant ponds. Their rotation c...

Re: Cotton rolls for lens cleaning?
Same method for me as my camera lenses. Foam buds with isopropanol, repeated with distilled water, dried with a makeshift blower (a large hand-pumped plant sprayer). Trick is not to over-wet, anything with fibres is a no for me.

Re: Issue with 2x and 1x objectives
I recently ran into this same problem. I bought a second Vickers M17 for the 1.25na achro' oil condenser and a second objective changer. The condenser is great but would not provide even full-field illumination for objectives below 6.3x and required swapping to to the original fip-top condenser for ...

A new rotifer found in the microbe aquarium. Powerful feeding currents. In the latter half of the video you can see the dorsal antenna being used to sense nearby dangers.

Not sure if this is a worm or nematode (other?), but unable to find anything similar on the web. Lives life at full throttle, observed for some time but wouldn't stay still for a decent shot. Odd behaviour, freed itself from this clump of detritus only to get entangled in another, and another, and s...

Hydra are essentially a hollow tube (blind gut), the feeding entrance is in the middle of the tentacle cluster. They can engulf large prey in short order. Here is a good video (not mine) of one in action: https://youtu.be/SS_HYY97ehw
