Secretan 10cm large table top telescope +/- 1850
Early (+/-1855) 10cm (!) Secretan table top telescope with all the eyepieces and finder scope.
the scope has a very beautiful dark varnish. No cleaning needed. Will leave it as it is.
19th century table top telescopes have normally a diameter of 60mm or 75mm. Larger models are very rare.
A very nice example of the classic French terrestrial and astronomical refracting telescope, here in a perfect original condition with all original lacquer entirely preserved and in original wood case.
Comes with a rare finder scope
