Logitech C270 Hd Webcam Black
Muredac Ford
I have recently modified a Logitech C270 webcam to use with my telescope and thought someone might find a write-up useful. I have included a few links below but I don't have any affiliation with them.
When I disassembled the webcam I found it has an 8mm threaded lens, so there was no way to attach the webcam adapter. Luckily I found a part on Thingverse that someone designed for exactly this purpose:
I found a 3d printing service on eBay and got 2 of them printed out and sent to me for a few pounds. I think it would have been better if I get the printed in black to make them more opaque, but it didn't cause any problems.
To install it you simply remove the original lens holder from the board by removing the 2 screws on the back of the circuit board and screw the printed one on in its place. This does expose the sensor so be careful not to touch it!
The next issue was enlarging the hole in the front cover of the C270 case to allow fitting the webcam adapter, I did this with a dremel and made a bit of a mess but in the end it looks pretty neat with the adapter screwed on:
1 - There is an LED on the board to show when the webcam is on, I covered this with a small bit of black tape and also stuck some black tape around the outside of the printed adapter to make sure no light got through from the LED
Lastly, most of the weight is in the bracket fixed to the back of the webcam so I wanted to remove this. If you peel off the little round stickers on the end of the hinge you can remove a screw, push out the hinge pin and remove the bracket:
After all this I finally got around to testing it out a few nights ago in my Skywatcher 127 MAK. I installed it directly into the back tube of the telescope without the diagonal, just a moon filter installed. The field of view is about the same as a 10mm eyepiece in my scope, and apart from being a pain in the backside to focus I got a few nice pictures of the moon. I recorded some short videos using SharpCap and stacked them in AutoStakkert, results below:
should give a flat white image on the screen. If that's not working reliably then there may be an issue with the unit or perhaps the gain settings, I assume you're using sharpcap to capture the video? I noted that you can set gain up to a point then thereafter more gain meant a dark image with an un-modded C270. I may well mod it for astro at some stage after my experiment with a IP-CCTV module once I've had a chance to test that one out.
I have a Logitech C270 webcam. I used it for years on my windows computer without issues. The video stopped working some weeks ago. Firefox and Skype say that some other program uses the camera. Windows Camera app shows black picture without any error message. The microphone works fine btw.
I was out of ideas, so I checked the camera with my Linux laptop. Again the laptop knows about the camera, but no picture, no errors. Based on this I guess it is a hardware issue. Before throwing the cam in the trash, I just want to ask if you think that I missed something.
I'm having a weird error with MS Teams on Desktop. On my side (with the little preview window), my camera shows in colour and comes through clearly, however everyone else in the call with me sees me in black and white/semi-distorted.
I have tested this in other video apps (Discord, WebEx, Facebook Messenger) and they all work fine showing me in colour, but on MS Teams it turns me black and white. I can see this if I turn on 'large gallery' or 'together mode', but otherwise I can't see it. Going into settings to check my camera shows it in colour as well.
I'm using a Logitech HD Webcam C270. I have unplugged and replugged the camera in, tried updating drivers (they are up to date), and have re-installed teams. The problem seems to be with MS Teams, not with my camera given it doesn't occur in any other app/program
I have the same issue with a Logitech C920 camera. Only happens on Teams, black and white with color displacement. Every other application works fine, including Teams on Browser. Only the Teams App has the issue.
It works fine on discord, looks fine in the preview picture on teams but as soon as i enter a teams conversation the colors go mute and it displays black and white for the other participants while still showing in color on my end.
Just joined to try and find a solution to this! Same thing been happening to me for the last month or so, have gone through numerous re-format and re-install of Windows and even set up a separate Teams account on another machine to test / replicate the issue.
From today's rebuild of windows, Win 10 Pro x64 installs nvidia drivers 456.71 during its install process and teams seems to work ok between my computers (using my Teams account) and between a colleague using my work account. Upgrading to the latest (currently 460.79 or the hotfix 460.97) geforce drivers gives the black and white output but from my testing 457.09 was ok. I looked in more detail at the nvidia drivers and noticed HDCP was complaining about a repeater over display port (even though direct from card to monitor) so I changed to HDMI and it was back in colour between my local machines. However after excitedly calling a colleague to say it was fixed it was again back in black and white. Is it possible my organisation applies settings (even though using personal computer)?
I also had / have a Logitech C270 HD and at first thought it was that which had gone wrong (I had opened it up shortly after buying since the fixed focus was off and needed to adjust it). Also now have a Brio 4k since the price of the C270 almost trebbled in the last 6 months figured may as well get an upgrade and it also does the same thing going to black and white but without the red / orange halo / spludges in the corner of my screen. Spending more time swapping both the C270 and Brio between multiple systems the cameras are defintely fine.
One observation I have made with the new camera though is Teams starts in colour, the camera feed refreshes once, still in colour then about 6-9 seconds later it happens again and it is this point where it would transition to black and white. Looking closely It also appears that Teams drops the resolution of the camera (even if it doesn't go B&W) so half wonder if it's going into a lower bandwith mode or some compression which is causing this effect to trigger. Interestingly if you apply a background effect that is also in black and white so it is applying this to the outbound feed rather than the camera (hence the preview window still looks ok). Of course if there were some settings / info to pull up about the camera this may help. The log files doesn't say anything about these refreshes.
@UK_Dave I've been struggling with the same issue for the past two months and initially attributed the issue to the fact that the Logitech c270 webcam was listed as an image acquisition device under my hardware in control panel (along with my HP printer/scanner). I tried all the possible drivers to no avail. My Teams version is the latest available. In Teams, after a few seconds, my image turns black & white with an orange smear, even if my preview box displays the image regularly. I do too have a Nvidia Geforce graphics card and will try your OBS workaround.
I also reverted back to Nvidia driver version 457.51, which has resolved the issue for me. This appears to be an Nvidia driver issue with their latest version causing these problems. I have had Teams meetings all morning and everyone has told me that my video feed is fixed.

The Logitech C270 webcam is compatible with most major messaging applications like Skype, Windows Live Messenger, Yahoo Messenger and more, giving you a wide selection of use.
Fluid Crystal technology provides smoother videos, sharper pictures, richer colors and clearer sound in real-world conditions. With the automatic light correction, even if you make a video call in dim or poorly backlit settings, the camera will intuitively adjust to produce the best possible image.
The built-in noise-reducing mic makes sure your voice comes across clearly, even if you\'re in busy surroundings. This flexible webcam comes with a universal clip for mounting so you can either attach it securely to your screen or sit it on a shelf.
