Yes I just checked and it has a 4x objective lens, give me some examples of interesting things I can put under? like celery for example?

thanks but I don't happen to have one in my apartment

Hi.. I have an AMSCOPE 490 series telescope I bought many years ago which is just sitting on a desk under its protective cover, what can I do with it? Its my days off from work today and tomorow and wanted to look at realy cool things, so far i looked at salt and pond water and onion skin I think.. ...

thanks for the tip

Do you have access to moss nearby? You could try taking a sample of moss and placing it in a small plastic cup of water, then waiting for a few days for microbes to grow from it. I found lots of rotifers starting to grow from this stuff. :mrgreen: moss as in pete moss used to grow plants from seeds...

Other than water from the river what are some other live samples I can either order online or find in my home that I can examine with my compound microscope? Just looking for general observation fun.

in the amscope software that came with my MU300 camera, when I record video without checking the time limit box, it should stop recording when I hit the button but it only keeps 30 seconds maximum about even if I let it run a few minutes, why is this? it seems to have a maximum limit on the file rec...

I figured it out, I wasn't getting close enough to the slide with the 40x, I was afraid I would crash into it, it works.

I can look at water samples fine with 4x,10x objectives with the 10x eyepiece but as soon as I try to use 40x objective i can't focus at all, is this normal or did I break it?

Is it safe to keep the jar in my bedroom?

if i get a jar of river water locally how long will the organisms stay alive if i leave it at home in that jar with some air on top? does it require anything to keep alive? lets say i wanna study samples of that jar for a month, doing weekly samples

What other liquids I can find locally or in the house would contain living cells I could see under bright field... I threw out the river water last night for fear of contaminating my room so I don't have anything to look at today.

Thanks, I have a few questions. Can I wash the slides and slide covers and re-use them? or is that not recommended? Also, looking at the slides this morning I don't see the living organism anymore, did it dry out overnight between the glass and glass cover and died? thanks

So yesterday I went down to the river and picked up some water from it, I recorded the first slide I viewed (about 5 seconds) and this is what I saw. Anyone know how I can learn to identify the organisms? anyone know what it is called in this slide? thanks

I didn't get my first slides yet but when I look in my microscope binoculars with the light on and I see my circle there are hairs from my face too, so yesterday I went to get my eyebrows done as the esthetician to trim them but I still have this problem, so I'm not sure if its my eyelashes or eyebr...

is it normal that when i move the fine tuning knob on the microscope that I don't really see the stage go up and down but a barely tiny tiny movement ?? or is it my eyes?

Here's a picture of it..

Yes, T490B. sorry about that, I will go update my first post!

Thanks

Today Purolator handed me my first microscope, its an Amscope T490B which can be upgraded to darkfield and phase contrast directly by amscope accessories. I'm waiting on another box that contains some slides and a 3MP usb camera. I set it up on my desk today but don't have any slides to use with it ...

thanks guys, now with this microscope can I view normal non-living cells just as well as living cells? i'm new to this so i don't want to assume anything.

So I'm narrowing down to the scope I want to buy, I want to view living cells and found out I need a phase contrast scope and I'm not buying anything used. This is what I found, from what I read it seems to do everything I need, I also don't have to use stains to view the living cells. http://www.mi...

Thank you for the detailed clarifications, so far I'm going to go with the Omax.

I don't have a DLSR camera.. also how do you know the unit I want to buy is brightfield? i did a search in the specs and don't see that mentioned or is that the default for compound microscopes ?

yes of course, that's why I choose that kit because of the 5MP USB camera and software.. And yes an optional darkfield kit is available and comptatible for that microscope as well, but out of the box will I see live cells moving? or does it require the darkfield kit?

I am not interested in anything used.

Oliver, I think the microscope I had ordered and cancelled 2 weeks ago had all those requirements, can you confirm this? I will re-order it if that's the case. http://www.microscopenet.com/omax-2500x-digital-microscope-cameraslide-preparation-kitcleaning-kitbookblank-slide-p-11398.html I appreciate ...

Excellent answer! Thank you so much.

what kind or specific brand/model in the entry level budget range microscope would I need to buy to view living cells.. like for example water from a pond, if i wanna see things move, or blood cells, or anything that can be seen moving.. thanks

Is there a chemistry set kit for adults? All the ones I seen are for up to high school kids
