I am working on two modest projects, both of which require accurate coordinates (RA and declination) of Polaris several hundred years ago. I have been using a spreadsheet of my own doing to calculate precessed stellar coordinates using the formulae in Meeus, but I'm not very confident in the results as I have only one sample giving confirmed values. I am hoping someone in the sundial brain trust can direct me to an available trusted source of Polaris coordinates for years in the past. A few accurate values that I can try to replicate would also be useful.
Best regards,
Jim
