Changes to W30

We've made two changes, added a guider so that longer exposures are possible and added a longer dew shield.

We've had some trouble with glints of stray light on some images during bright moon times.  Hopefully the longer dew shield will reduce that.

Interestingly, although the company that makes the guider advertises it as a guider, it has to be used with a star diagonal as the light path is too long to mount the guide camera in the focuser.  So it's not designed as a guider at all.
