    Exactly. My SNO has a similar scope.
    I was even puzzled first: why people need
    the stupid full-view mirror which absorbs 1/2
    of the light?
    
    I tried to convince Ken (of Astra/Celestaire)
    to make a similar scope for Astra; he does not listen.

    Yes. And most people just don't know what a good sextant
    scope is, because they had no opportunity to try.
