Frank is right about magnification being the important parameter in seeing stars during the daytime.

For any magnifcation, a star shows as a point source of light in the background of scattered light from the atmosphere. The higher the magnification the smaller the field of view and the less scattered light is picked up.

Increased objective diameter picks up more starlight but also more scattered light, no improvement in contrast.

The higher the magnification, the smaller the field of view and the harder it is to find the star but as Frank suggests a computer controlled scope will sove that.
