  2. Bayer matrix Imaging chip Theoretical resolution for 80 mm dia aperture at 656nm = 1.73 arcsec For maximum sampling 1.73/2 = 0.87 arcsec Webcam pixel size = 5um Giving a resolution of 2.06 arcsec per pixel. This is not the whole story.

  3. Theoretical resolution for 50 mm dia aperture at 656nm = 2.76 arcsec For maximum sampling 2.68/2 = 1.38 arcsec For comparison the PST has a theoretical resolution of 3.45 arcsec DMK monochrome video camera 1280 x 960 Pixel size = 4.65um Giving a resolution of 1.92 arcsec per pixel. However, using a 2.5x power mate gives a pixel resolution of 0.77 arcsec @ 656 nm. This is ideally suited for an 80mm f10 scope.
