I RECOMMEND VIEWING THE PLANISPHERE IN ITS ORIGINAL SIZE!
It says (in Dutch): "HEMELPLANISFEER of KAART van den NOORDELIJKEN STARRENHEMEL,
getrokken uit den ATLAS van BODE, doch enigzins veranderd, door FRANCIS WOLLASTON, F.R.S."
In English: "CELESTIAL PLANISPHERE or MAP of the STARRY HEAVENS,
drawn from the ATLAS of BODE, but slightly altered, by FRANCIS WOLLASTON, F.R.S."
Reference is made to Johann Elert Bode (1747-1826) and Francis Wollaston (1731-1815).
