It's a CMOS sensor with quite small pixels I think (no specs from MS). It's a 10 FPS at 1280x800 RGB24 capable camera so it's something bigger. I'm playing with few webcams for "fun" and to check, mythbust some astro-webcam myths
Here are few Moon shots from the HD-5000 (SCT 8" at f/10, images converted to grayscale, SharpCap - capture, AVIs stacked in Registax, deconvolution in AstraImage):

Comparing the crater sizes with image from
Basler Ace with 5,6x5,6 micrometer pixels I say this CMOS has smaller (which give higher resolution). CMOS like to have even 2,2 x 2,2 micrometer pixels. (Unless the webcam is interpolating higher res).
