My new Celestron microscope
My Celestron CB2000CF arrived a couple of days ago. I'm happy. It's not high end but has more capability than my AMscope M149 student scope. I think this will suit me for a long time. Did I say that I'm happy?

Microbe identification
I am beginning to look at water and soil samples. Is there a basic reference to help me identify what I find? Not looking for a technical college text - more like "microbes for dummies".

Bacteria on your hand
Here's a link to an interesting experiment. Has anyone here done this?

Re: AMSCOPE 490 series
Just about anything in your fridge or cupboard. Aspirin, starchy foods, dust, cheek swab, blood if you happen to have a cut, fabrics, paper towels, your fingerprint on tape, greenery around your apartment building, and the list goes on. My microscope is of the same 490 series and I've had lots of fu...

Your detailed response just leads me to do some online research into the process - just out of curiosity. My "lab" is one end of a dining room table. I lack knowledge and resources to go much beyond what I'll get from the kit.

I am intrigued by a student kit to extract plant DNA. What optics are necessary to view DNA?

Re: mechanical stage problem
Hi, Bob -
Thanks for your reply. I disassembled it and still couldn't figure it out. At a cost of $23 I simply ordered a new one. Much less frustrating. I'm using a student scope from AMscope. I'm a rank beginner so it fits my capability at this point.

I finally learned about polarizing film. My budget student microscope doesn’t have any place to put normal polarizing filters. My ‘net searches took me to a clever device, (pic above) but the site referenced in the article no longer exists. The article was written in 1998 so that’s not a surprise Is...

I'm looking at Beginner Microscope Experiments on microscopemaster.com For the experiment looking at leaf structure, it call for glycerin as a mounting medium. Why? When is this the correct choice?

Re: USB camera issues
Thanks very much for your help. I'm disappointed at the facts, but it's true that You Get What You Pay For. I'm hopeful that I'll be able to upgrade, but in the meantime I'm enjoying having a closer look at the things in my world.

Re: USB camera issues
Thanks for your replies. My scope is an Amscope M149 student microscope. The camera model is MD35. Since the whole thing cost less than $130, I'd suspect that it doesn't have its own optics.

A very Newbie question I have an inexpensive Amscope student microscope with 10x and 25x eyepieces and a 640 x 480 USB camera that fits into the tube. There are adapters that fit to the eyepiece to accommodate the camera. When I have the camera directly into the tube with no eyepiece, everything’s g...

Re: Hello from Florida
Thanks for the welcome messages. Kosher salt is somewhat interesting. I'll try dissolving and evaporating table salt - sounds interesting. I also have Maldon (flake) salt to look at. Mold is next - there's some moldy cheese in the fridge. All of this helps me learn about my scope. Retired in '04 at ...

I am about as newbie as they come. Bought one of those cheap digital microscopes last summer. Had some fun with it, but it was like a “gateway drug” – I want more. Christmas brought me an Amscope student microscope with a USB camera. I have no particular area of interest; I just want to know about e...
