Foarte frumos.
Multumim pentru informatii.
Adaug si eu o fotografie si cateva informatii, pe care oricum le-ati mentionat in PDF :
"With this refracting telescope, built in 1828/29 at the Optisches Institut in Munich by Joseph von Fraunhofer, Neptune was discovered in 1846. The telescope's lenses are 244 mm in diameter and it has a focal length of more than 4 metres."
