[Avodah] Amod Hashachar

[SBA]

For centuries, rebbes and their talmidim have been teitching (Brochos 1:1):
'Ad sheyaaleh amod hashachar'  referring to the 'morgen shtern' = the
morning star. (Anyone who went to a Yiddish cheder, and was taught
differently, please comment.)

I have in the past weeks had reason to look into this and there is no doubt
that this is incorrect. Not one of the meforshim on Mishnayos explains it
thus.

I wrote 'for centuries' as the Tosfos Yom Tov already writes:
"Yesh regilin leposroy kochav hashachar...ach bekaan ein nachon.."

So too does the Gro write in Shenos Eliyohu:
"Amod Hashachar: hu heir pnei hamizrach - velo ayeles hashachar..."

Kehati brings 4 pshotim, not one as morning star, (with one inferring that
'ayeles hashachar' is not the 'kochav hashachar'.

See also the Mishna Berura's view 58:18 dh: 'Amod Hashachar'.

>From Wikipedia for "Morning star"
>>Morning Star may refer to: The planet Venus, also called the evening star.
Venus..is the second-closest planet to the Sun,...It is the brightest
natural object in the night sky, except for the Moon, ....reaches its
maximum brightness  shortly before sunrise or shortly after sunset,
for which reason it is often called the Morning Star or the Evening Star.<<

Any melamdim and magidei shiur here who can comment?
