so
became a liability, because we had then to bring on light again
(I brought on the finger tip lights to do this).
Gordon knows how
strongly I feel about the star chart device.
This is a valuable tool.
But it required two tools and a slider.
Actually, two tools, with
sliders on each to use them.
I had to take one tool which gave me
a reference in the time that had elapsed to come back to the star chart
which had a reference for one time - I think it was an hour's worth.
So I had to come over here and compute.
For example, say I had S hour J
and 20 minutes, so I'd run down 5 hours and 20 minutes and look across
and this is equivalent to say 53 minutes.
So then I would say, Ah,
53 . minutes; so then I would race over here and set the little window
thing on the index of 53 minutes and this thing is floating around
and I would stamp it off and get it out of the way.
This is quite
a chore.
It really is.
So now we have included this on the flight
plan itself, what index of the star chart to use.
So we have
simplified this task quite a bit.
Cameron - As far as the star charts are concerned, fluorescence
Roman - Suppose you had an ultra violet lamp · in the capsule -
Schirra - If you kept it up?
Roman - That's what I was going to suggest - - (fluorescent paint on
charts)
Not depending on storing it up and letting it go down
afterwards.
Gill - You mean keep it on?
Roman - _Well, depending on which looks more desirable.
But
you could set that at a level where it would not blind you and
