Of course you come from a community of celestial sphere unfortunates ....

Of course I don't.

An astronomical hypothesis was generally accounting for motions of various celestial objects and particularly the planets and the moon and before that the Sun in geocentric astronomy. When accurate clocks arrived on the scene they employed it carelessly to circumpolar motion and tried to equate daily rotation directly with that motion and modeled orbital motion in as an afterthought.

Unless you want to see the Lat/Long system butchered in order to make way for identification and magnification using the Equatorial Coordinate System then I suggest you follow the rules of the person who actually was a one man version of NASA -

"The application of a Timekeeper to this discovery is founded upon the
following principles: the earth's surface is divided into 360 equal
parts (by imaginary lines drawn from North to South) which are called
Degrees of Longitude; and its daily revolution Eastward round its own
axis is performed in 24 hours; consequently in that period, each of
those imaginary lines or degrees, becomes successively opposite to the
Sun (which makes the noon or precise middle of the day at each of
those degrees and it must follow, that from the time any one of
those lines passes the Sun, till the next passes, must be just four
minutes, for 24 hours being divided by 360 will give that quantity; so
that for every degree of Longitude we sail Westward, it will be noon
with us four minutes the later, and for every degree Eastward four
minutes the sooner, and so on in proportion for any greater or less
quantity. Now, the exact time of the day at the place where we are,
can be ascertained by well known and easy observations of the Sun if
visible for a few minutes at any time from his being ten degrees high
until within an hour of noon, or from an hour after noon until he is
only 10 degrees high in the afternoon; if therefore, at any time when
such observation is made, a Timekeeper tells us at the same moment
what o'clock it is at the place we sailed from, our Longitude is
clearly discovered." John Harrison


The key feature is how to exploit the 'average' 24 hour day and convert that average into constant rotation at a rate of 4 minutes per degree of rotation but that means starting back in antiquity with the creation of the calendar framework.

I offered you the opportunity to develop software that uses the annual motion of the stars minus circumpolar motion as this long term observation will produce imaging of the planets and moon as they actually move through space and outside their motion from horizon to horizon each night .

Golden Retrievers require regular grooming and occasional baths. They should be groomed at least once a week, and every day during heavy shedding. They should be bathed every two months. Their coats shed somewhat during the year, but are known to shed profusely twice a year. You're welcome
