Question: Is this device compatible with Windows 7?
Document: I finally got it to work, but it's horrible! The s/w says it's win 7 compatible, but you have to run it in xp sp 3 to make it appear on screen. Then, I can only get an image when I use the lowest pwr on the scope. Anything higher and the picture is too large to fit on the screen. My microscope even has a device specifically on the tri ocular lens which can be rotated up or down to get the image in focus.
This is a really cool idea, but not implemented very well with this particular product. "Plug and play" means I should be able to plug this in, install the drivers/software, and start using it. Unfortunately, the Celestron 44421 Digital Microscope Imager doesn't actually function as a plug and play device. I tried it on my desktop PC and laptop (both running Windows 7).
But most microscopes have a 10x or 20x eyepiece: Celestron reasonably compromised by making their eyepiece 15X, so it is not too different from either one. It would be nice if it were the same mag as your other eyepiece, but no big deal.All in all, the optical quality is excellent and the device works great on XP and Windows 7 once you figure out a way around the worthless software. A remarkable product for the price.
i wanted to put a few notes here for others to save them the effort i just went through. i use windows 7 and the software installed and worked ok for about four minutes, then froze my computer. i now find i can only run it in 'compatability mode', but then it seems to work fine. the pictures are really excellent for a 35 dollar device, and for that it gets its four stars.re: focusing. focus the microscope by eye.
This item works as described and yes, works great with Windows 7. The device is almost completely plug n' play. I use this with my netbook in the anatomy lab at the college I work at when tutoring students with histology (I transferred the installation drivers from the CD-ROM enclosed to a flash drive and it worked great!). The resolution isn't as sharp as say a microscope camera system with an adapter ranging $300-$500, but does the job with superb results.
I also get the black screen on my computer when trying to increase the magnification. I spent a lot more money on this because I bought it at at the event. They made it look so great and wonderful. To me, when a product says it is compatible in win 7, that means it should RUN in the win 7 format and not have to be dummied down to make it work. I did contact the company and told them all the things I tried to get it to work.
I purchased this camera at a convention. I have the Amscope  40x - 2000x tri ocular dark microscope I purchased on Amazon..  As other reviewer stated, I wasted two days trying to get my win 7 computer to &#34;see&#34; the camera. Got the same error about not being hooked up to the computer or being used by another device. Like the other reviewer, I too loaded the s/w, deleted it, reloaded it, rebooted my PC, etc.
First, consider the price range. This is a very inexpensive device. The software works (I'm running it with the Microsoft Vista operating system). But it feels like a Windows 95 application.
It works well and mounted easilly. I did not need the installation CD with Windows 7. I'd buy it again.
Does everything as promised. would be great for classroom presentations. Can't handles windows 7 software  very well but what can.
Answer: Yes, it is compatible.
