Shark bite,
I bought the exact same webcam nosepiece adaptor a few months back for my Logitech C270. I haven't used it for planetary work yet, but used it temporarily as an Autoguider and it actually worked a treat. The only issue was that I was limited to brighter stars than a propose built Autoguider, but that is a limitation of the webcam, not the adaptor itself.
So if your webcam has no issue having the nosepiece screwed on, they are pretty good.
Goran.
