μεταχειρισμένα Celestron C90 - 1000mm. Μεγάλος τηλεφακός ή τηλεσκόπιο για επίγειες ή \ και αστρονομικές παρατηρήσεις με 4 προσοφθάλμια, 4 φίλτρα, ερευνητή 5Χ24mm και αντάπτορα για μηχανή NIKON όλα σε βαλίτσα

The C90’s visual back is T-threaded, so you can put your DSLR on the back with a T-ring ($10 or so). But be sure to tone down your expectation as it will never be as good as SCTs.

For terrestrial use, this makes it awesome as a super-long focal length telephoto lens. The close focus is at 15 feet making it very ideal for some sports like target shooting or even hunting where usually 100-200 yards distance are being used.

For astronomical viewing the C90’s sharp optics make it a great choice for looking at the Moon, planets, and double stars.
