    Kollsman periscopic sextant
    From: Douglas Simpson
    Date: 2009 Aug 9, 07:33 -0700

    I have just purchased a kollsman periscopic sextant and when I look through 
    the eye piece I can see the bubble but the view is only through the 
    projection lens. I can see nothing through the periscopic lens - is the 
    shutter blocking the view? I have pushed the actuating button to clear the 
    shutter but this does not seem to work. Do I have to take off the LHS cover 
    to clear the shutter? I have been led to understand that you should be able 
    to take a celestial shot without operating the averager and hence there 
    should be a clear view through the periscopic lens all the time. Any ideas?
    Regards
    Doug
