    I've reduced many sights with the Ageton method on a blank sheet of
    paper without referring to any instructions. It is not difficult if you
    stay in practice. I think any expert celestial navigator should be able
    to do that (including all the corrections) with his favorite reduction
    method. The steps should all be so familiar they can be performed by
    heart without the prompting of a form. (But a form reduces the chance of
    a mistake.)
    I filter out messages with attachments or HTML.
