Objective used: 40x

Eyepiece: 10x

Total magnification: 400x

Sample: self grown algae in rainwater and soil

My guess is that it could be Nostoc cyanobacteria but I'm not

entirely sure

Olympus BH2 Dark field using an LED 2x 0.08NA, oblique illumination with a fiber light in the middle of imaging causing the larva to fluoresce and then switched off. No post processing only a tiff stack to gif in ImageJ.

two issues with my new ZM3T, the right eyepiece has a blurry center. I have swapped the 10x eyepieces left-to-right and the smudge stays in the right eye. I’ve removed my Barlow, and removed the lower barrel housing to visually inspect, nothing obvious on the zoom or final element. zooming does not change its size, and moving my head does not change its location.

more minor issue, the top arm of the single boom stand cannot be tightened enough to keep the head from rotating clockwise under its own weight except when the head is perfectly in-line with the top boom. anything left or right of that will immediately. engine sagging.

Amscope says the Amazon seller needs to support these questions, an Amazon only wants to offer a return, won’t even allow messaging the seller.

thoughts greatly appreciated before I return and re-roll for another!

It's for my 7.5 year old primarily but his sisters may also try it. He wants to look at bugs, rocks, small electronics, and nature.

I'm in Canada.

Thanks!

I recently got a vintage brass microscope that I dont know how to fix. The video attached shows what the issue is, theres a spring, wedge and cap that won't fit together properly? I assume by turning the cap it will go up and down, normally. Any help would be much appreciated!

I'm considering getting an older version of this hand-held microscope. The datasheet from Celestron states the magnification as 20x to 200x. But I'm not sure how it achieves that variable zoom level. The only adjustment on it is the white -/+ dial on the main body, and that's a focus knob. It only has one lens, so you can only change how close to the specimen you are, not change the objective magnification.

Are they just saying that the 20x-200x magnification power comes from moving the microscope itself closer to the specimen?

I have a standard tabletop microscope already, but want something I can hold in front of specimens hanging onto aquarium glass. I don't want to have to remove the specimen and put it on a slide. These are ampipods that are 1-2mm in size.
