Default Daytime Observing!

visible, as is Mars, and the brighter stars are easily seen.


Can you actually see some stars during daytime? And Saturn?


Well, seems you can. Just found some good sites about this.
Must say I'm quite surprised and will try it out.


'To reduce Watches to the right measure of dayes, or to know how much
they goe too fast or too slow in 24. hours.'

" Here take notice, that the Sun or the Earth passeth the 12.
Signes, or makes an entire revolution in the Ecliptick in 365 days, 5
hours 49 min. or there about, and that those days, reckon'd from noon
to noon, are of different lenghts; AS IS KNOWN TO ALL THAT IS VERS'D
IN ASTRONOMY. Now between the longest and the shortest of those days,
a day may be taken of such a length, as 365 such days, 5. hours &c.
(the same numbers as before) make up, or are equall to that
revolution: And this is call'd the Equal or Mean day, according to
which the Watches are to be set; and therefore the Hour or Minute
shew'd by the Watches, though they be perfectly Iust and equal, must
needs differ almost continually from those that are shew'd by the Sun,
or are reckon'd according to its Motion."

The pre-Copernican astronomers referenced planetary motion from th
point of view of a stationary Earth,the heliocentric astronomers
referenced planetary motion from and orbitall moving and axial
rotating Earth,the 17th century empiricists referenced axial and
orbital motion of the zodiacal framework hence we now have numbskulls
who think astronomy is a magnification hobby that occurs at night.

The freakish situation where axial and orbital motion is referenced
off a celestial sphere leads to the catastrophic view of axial and
orbital motion as a mixture of astrology and creationism -

In the noble history of human reasoning and discovery,there is nothing
worse than the fictional forcing of tying axial rotation to the return
of a star to a meridian,it is beyond insanity but unfortunately it is
now the dominant view.

I do not mind what you have done to yourselves,it is the rest of
humanity who really needs an authority to handle the destruction of
astronomy,its methods and its insights by people who now wonder if
there is such a thing as 'daytime observing'.
