Camera sensor cleaning light

Have you seen this thing before?   https://www.bhphotovideo.com/c/product/1117520-REG/visibledust_16111549_quasar_plus_7x_sensor.html
Never seen this before.  The problem I always had with cleaning my camera sensor is seeing the dirt and muck on my cameras sensor.  Seems this thing helps you see what you are missing with your naked eye.  

I don't suppose are you using one of these or similar?  

I have one, but its as easy to photograph a blue sky stopped down to find the grubbies.

Expensive! I know nothing about it. Since some timeand with pleasure, I've been using this for my FX and
medium format sensors

Wait, what are you doing here?  Are you literally photographing the sky, but how do you locate the dust spots from that?  I get you'll see them, but their exact location?

Take a shot of an light even surface that is completely OoF
but well exposed and that alone will reveal the dirt. All is
remembering that the result is upside down.

It need not be oof either...and yes, they'll reveal themselves.

Per Photography life....
How to see sensor dustIf your camera has dust on its sensor, you can quickly spot it by doing the following:

1. Set your camera on  Aperture Priority Mode .
2. Set your  metering mode  to  Matrix/Evaluative Metering .
3. Set your  camera ISO  to the lowest number such as ISO 100 or 200.
4. Turn off Auto ISO.
5. Turn off autofocus and set your lens on manual focus.
6. Set your  aperture  to the largest number available for your lens by rotating the camera dial. For example, the minimum aperture on the Nikon 50mm f/1.4G is f/16, so if I were shooting with this lens, I would set my aperture to f/16.
7. If you are outside, point your camera up at the clear blue sky and take a picture. If you are indoors, find plain white paper, zoom in all the way so that the paper fits the whole frame, then make sure that the lens is completely out of focus and take a picture. If you are in front of a computer, open up a text editor such as Notepad, maximize it to the screen and then get as close to the monitor as possible so that only the white color is visible in the frame. Make sure that your focus is way off (completely out of focus) – that way only dust particles will be visible.
8. Zoom in on the image (rear camera LCD), scroll from left to right and top to bottom all over the image and see if you can find any dark spots.
9. If you cannot see any, your sensor is clean. If you see dark spots like in the above example, then your sensor has dust on it.

 Again, I always found the spots with focus at infinity.....

Good set of notes above

Using a light uniform OoF scene will prevent real object
to be confused with dirt and make results easier to see.

That's why we shoot an empty sky, no objects to confuse....I pull down a window shade when too lazy to go outside (or raining) and use that too.

That might be helpful. Trying to see schmutz is not fun, and the images you use to identify spots are reversed (both axes) from where the dirt actually is.

Yep, look at that big 'old spot there!  

Now this is a good idea to have.  Glad I clicked on this thread.  

G'day Toby

If you carefully use the scroll bar to the right-side of your computer screen, and wander the blue image up and down 3-4 times, you will actually find 5 dust specs across the image
