After he had given his first planetarium to his nephew, Wildrik Botjes constructed another planetarium with some modifications and additions to his earlier design. Botjes' second planetarium is now on display at the Eise Eisinga Planetarium Museum in Franeker, Friesland, the Netherlands (about 60 miles west of Botjes' home), although it is no longer functional.

The premier display of the museum is the Eisinga planetarium, which was completed in 1781 and is the world's oldest working planetarium. (See also an independent website with a nice photo display of the Eisinga planetarium.) This planetarium may have played a part in Wildrik Botjes' decision to construct his planetariums.
