Dear Kermit,

Yes I used Frank's calculator:-)
I cannot publish ALL row data (I have to much) but here is the data for
tonight.
My place: N40d 27.2, W86d55.8 Termometer: 60 Barometer 740mm
(sorry: 29.13 inches, my barometer is German:-) GMT March 29.
SNO-T, IC=-0'3 from Sun, 6x Kepler scope. Watch (set on GMT) 3 sec fast.
Row data (GMT watch reading; sextant reading):
1. Moon (Near limb)-Jupiter:
00:31:50 35d21'1
00:34:03 35d22'
00:35:25 35d22'8
2. Moon (Near limb)-Venus:
00:37:24 23d50'
00:38:31 23d50'
00:40:13 23d50'2
Break for a cup of tea.
3. Moon (Far limb)-Mars:
00:57:09 77d14'9
00:59:24 77d14'4
01:00:00 77d13'7
4. Break. Index check: Rigel, IC= -0'2 or -0'3 (not sure).
Some small star, IC=-0'3.
Reduced the sights with Frank's calculator using IC=-0.3.
5. Moon (Far limb)-Jupiter, again, using stopwatch instead of wrist watch
stopwatch is exact, started from Internet GMT:

01:12:33 35d35'0
01:14:52 35d35'7
01:16:00 35d36'1

Remarks. Sitting in a chair, in the case of Mars, facing Mars.
Holding the sextant with two hands. Adjust and look, adjust
and look...
Stopwatch more convenient (don't need to put eyeglasses on and off;
stopwatch has a hudge dial (2.3 inches),
and I use a microlight from Celestaire to
read the time and sextant. Native SNO illuminator is not enough for my
eyes, but magnifier helps a lot, so I can read without eyeglasses.
Stopwatch has two second hands: one can be stopped another continues.
Then I read the time, press a button, and the stopped hand joins the
running hand. Very convenient for Cel nav. Russian Molnia stopwatch,
dial reads to 1/10 of a second, but I don't care of course about 1/10
when taking Lunars, in fact one can safely round to 5 seconds:-)
