Tom,
You state in your earlier post that an astronomer in the article that your link to (mid 19th century?) mentions that the star Gamma (Y) Daconis shows a large negative parallax. There are several other descriptions of this star (assuming that is the star you mean, also known as Eltanin) which seem to offer a different view on this. For example...
https://www.universeguide.com/star/eltaninIt actually quotes two different parallax measurements spaced 10 years apart. The figures are given towards the end of the page. You will appreciate that an angle of just a few milli (thousandths of) arc seconds is very small and would be extremely difficult to measure with the kind of equipment available to an astronomer in the mid 1850s so it is no wonder he struggled.
Just noticed... I think the article in your link was actually published in 1902. Makes no difference though... to my case stated above.
Related to the topic of stellar parallax, I note it states in FE Wiki,
Firstly, we must understand that the stars in FE are small and a few thousand miles above the sea level of the earth. This change in distance compared to RE figures is due to an adjusted astronomical parallax on a Flat Earth. The angle of stellar parallax changes, as it does with the sun, when the earth is assumed to be a flat surface.
We should actually understand that the stars are neither small or just a few thousand miles away. They might need to be for FE theory to work but in reality they are not and astronomers have got good evidence to show that they are not. Secondly... solar parallax? How does that work since we don't need parallax to work out the distance of the Sun?
