Those observations are in twilight, and even so, a twilight observation would have a slightly higher (or lower) ecliptic than a midnight observation. The solar plane of the sun and planets is tilted. It is tilted in RET as well, except that it is claimed that the cause is the earth being tilted.
I have observed Venus, Jupiter through my telescopes within an hour of local noon so that can hardly be described as twilight. It's easy to do if you have a permanently set up and aligned mount. I simply tap in Venus or Jupiter into the handset and the mount slews to where they are in the sky. You then tweak the focus and gain settings to suit. Broad daylight is actually the best time to observe or image Venus as it hides the glare you get during twilight. If the seeing is good you can then find Venus with the naked eye at any time of day.
By solar plane I take it you mean the ecliptic. Which is of course inclined by 23.5 degrees to the celestial equator. So the ecliptic represents the precise path of the Sun through the sky. It is inclined by 23.5 degrees to the celestial equator
because of the tilt of the Earths polar axis. There is no 'claimed' about it. That is what gives us our seasons and why the Suns declination varies from 23.5N to 23.5S every year.
That is the model which I will take to be true and correct unless you've (FEers) got any better ideas which work just as well?!?
This "dish" is constantly tilting throughout the year, or rather wobbling, with the sun being a fixed location on that wobbling dish.
Based on FE theories, why is this "dish" tilting or wobbling throughout the year? Obviously if you believe the Earth is flat then you have to ignore the polar axis tilt which RE provides. So how do you account for this wobble instead?
The planets formed from an accretion disk which formed around the newly formed Sun. This disk formed in a plane which was in line with the solar equator which is why all the planets tend to follow paths through the sky which are very close to the ecliptic. Obviously I wasn't around at the time to witness all that but that's because the human lifetime is rather less than 4.6 billion years!
Again, if FE can provide any better explanations then I am all ears...
