Re: Focus on 475 scope

The mesh dome is generic, one is as good as the next.
It does not wear out.

The 475 does not have a nice sharp beam. It is inherently
about 1.5 minor divisions wide.

It is at its absolute best when the bandwidth limiter is
turned on to its lowest bandwidth setting.

If the glass screen, or the polycarbonate blast shield,
is dirty, the focus can appear even less sharp than
normal.

The 475A is a little better, as I recall.
