Actually, I never used this method, except in an "emergency". The
normal method used, was to get a couple/few morning sunlines and do a
running fix by moving them up along the course line and crossing them
with the LAN sight.

Now, with your explanation, Neal may be able to get a Local Noon sight.
Maybe, I'm still not sure he aware of what we are talking about. Hitting
a high noon fix with the Earth traveling over 900 MPH is kind of like
catching a Fly with Chop Sticks.

OTN your method is the correct way to take a Noon Sight. Even the
instruction that came with Neal's (Also mine) Sextant explains the Noon
Sight that way.

Some of the older model sextants used half mirrors instead
of the modern see-through mirrors that make it possible to
have the sextant picture a sunset at LAN. The older
sextants were harder to use.

You being old and retired, I figured you'd probably have
some antique instruments.

The horizon glass was a half mirror that was not at all difficult to use.
I'm not sure what you are referring to regarding "picture a sunset at
LAN" if you are talking about the brightness of the sun, shade glasses
took care of that. As for dipping the sight at the time, swinging the
sextant solved that issue.
G My sextant may now be considered an antique, but it's still probably
one of the best instruments built .... still has original mirrors.
