Celestron 44422 Digital USB HD Microscope Imager, 5MP CMOS Sensor, Mac & Windows Compatible, Black

As some have mentioned, this camera is about 30X magnification where as most standard eyepieces that come with the microscope is 10X, so that may be an issue with some users of this camera, so plan accordingly if you buy this one. After downloading the software from Celestron, the camera is ready, it works well and the image quality is good. Your lowest power objectives will give you larger images than you might expect at first but I don't find that to be an issue. For the money, it is a very nice camera and it gives me a larger picture on my Laptop.

My intended use for this product is to photograph and video cyanobacteria and other aquatic life. The imager works with Windows and Macs, but Celestron does not have an Android app for it. It does NOT work with generic USB microscope apps such a MScopes. The software you need must be downloaded from Celestron and I recommend you follow their links from their "store" entry for this item to get the right version of manual and software. Also know that the camera image is a fraction of the eyepiece field of view. The software does have graphic tools including a scale, but I find the calibration tool for that scale to be quirky. Overall a nice product but it could use a bit of refinement for the software, and an app for Android tablets.

I just received the Celestron – 5MP CMOS Digital USB Microscope Imager tonight, and loaded the Celestron Digital Imager HD software for Windows, but the Celestron Digital Imager HD software detector does not detect the imager connected to the Windows PC hardware. I bought this as used - like new, box was a little beat up, but the imager was like new.I opened a case with Celestron Support. Justin H very helpful. We determined in a couple of days that I had downloaded the wrong version of the imager software from Celestron.Uninstalled wrong version, installed good version, Working now as expected.The PC runs the latest version of MS Windows 11 Pro x64.

Outstanding picture quality for my students.

Let's start with the good about this very inexpensive camera. It would probably be sufficient for a child who is a beginner with absolutely no experience nor expectations. It will capture a rough image of part of what you are seeing but the image will be poorly exposed and the white balance will be wildly off. It can, easily enough, capture a rough image.The software is definitely the weak link although the camera itself isn't much better.The first problem with the software is that it is impossible to view the entire image area on the screen. When you open the software, you immediately get a live view from the camera but you are only seeing a tiny portion of that already small imaging area. Changing the settings has absolutely no effect on the display screen. I'm using a 4K monitor so I have plenty of resolution on my display to actually see the entire 5mp image area all at one time but the software doesn't seem to allow this.Not being able to see the entire imaging area in the software is compounded by the fact that because the imaging camera has such a tiny sensor (1/2.5"), at best, you will get a 2x image compared to what you are seeing in the eyepiece. Then, on top of that, your live view in the software is only showing you a tiny portion of that tiny 2x view from the camera.So, then I just accepted the fact that maybe that live view screen is simply for focusing so I focus and I go ahead and capture an image. Snapping an image is a slow, delayed process that requires about 3 seconds in total. Why? It's a rinky dinky tiny image! If I were snapping a 100mp image, I'd expect a bit of a delay but not at such a tiny 5mp resolution. This software is slow, clunky, quirky and provides very little control.The quality of the images are really lousy. The camera tends to blow out/overexpose highlights which really produces terrible images. There are some rudimentary controls in the settings of the software but this does not help. The highlights always seem to remain over-exposed and blown out no matter how much I turn down the brightness. Even when you change the settings to get the images looking a bit better, then next time you open the software, you need to change the settings all over again because the software always reverts to the default settings (which are horrendous).The white balance is always wildly off. My images turn out noisy and yellow... deep, dark yellow. I can manually adjust the white balance setting from its default 6000K down to 2700K but the image has color balance issues that vary across the frame. For instance, the left third of the image is always showing a magenta hue to my photographer's eyes.Resolution... When I did the math calculations for necessary resolution for various objectives when used with this camera, I found that this camera does not have enough resolution when using a 4x objective and it is obvious in the images. When you get up to 10x the image improves but it is still grainy, dull, very "uncrisp", and sporting the exposure and white balance issues mentioned above.There are definitely problems with this cheap camera with its old and tiny sensor but the biggest issue is the software. I cannot get this camera to work with any other software package either which only compounds the problem. If I could use better software, then I could possibly gain more control over the camera rather than being stuck with the crude control in Celestron's software. Unfortunately, I'm stuck with the lousy Celestron software and this software truly renders this camera useless.My current work-around is to use one of my photography cameras rather than using this Celestron HD Imager. It is awkward but the resulting images and video are worlds better than what this Celestron package can produce.

As mentioned in other reviews, this camera shows a highly zoomed-in view compared to the microscope. I have a Bausch & Lomb binocular scope. The camera fits nicely into the second eyepiece. However the camera shows only about 1/10 of the image that I see through the other eyepiece. As far as I can tell there is no way to zoom out to correct for this, so the camera is useless; I had to return it. Also, the camera is very sensitive to light and does not properly compensate when I use my super-bright light source.

Got this (5-megapixel version) for my daughter's LW Scientific Student Advanced microscope. Arrived today. I loaded the software onto a Windows 10 PC, connected the camera to the adapter, substituted the adapter for the stock eyepiece (with this particular microscope, you need a very small Allen wrench to loosen a very tiny screw to remove the eyepiece), plugged the Celestron Digital Microscope Imager into a USB port, fired up the software, and boom, worked like a charm, super-straightforward.At my daughter's chagrin I poked my pinkie with a safety pin and we checked out blood. The stock eyepiece magnification being 10x, the 30x magnification of the Celestron imager made the daisywheel's middle lens roughly as magnified as the big one typically is (300x, vs. 400x). The usual 400x big lens was suddenly coming in at 1200x. The resolution on the laptop's screen was excellent, and the photos and video came out great. Highly recommended.

It has too much magnification for a compound biological microscope and way too much for my stereo viewing parts scope. It resolves to about a 30x eyepiece and reasonable size samples wont fit in the viewing frame. It would be great if a reduction lens could be fitted to make it a 10x eyepiece in addition to the 30x.Also the software must be restarted if the 5v usb power is removed then reapplied.
