Poor image quality

Microscope: Zeiss Axioplan2

Amscope MU1403 camera attached to Dell laptop

Scope objective: 40x w standard 10x lenses

Sample type: Feulgen stained tissue samples from an amphibian

New to microscopy and trial&erroring with some samples. I'm having issues with both a limited field of view on live capture camera feed and poor image/video quality. It’s almost like the camera isn’t focused but I'm not sure how to fix that. I believe I've calibrated it but any tips or tricks would be helpful!
