Baader 3" Hyperion Focuser for Newtonian Telescopes with 40mm of Travel
- Professional focuser for Newton telescopes with 40mm extension length for highest loads
- Titanium oxide hard coated, very hard sliding surfaces with 5my fits, 1:10 reduction gear
- Scale with noctilucent scale engraving, vernier scale with 1 / 10mm reading accuracy (5/100 estimated)
- Non-reflecting inner diameter with 5 mm deep diaphragms and 76 mm free passage
Important note: The titanium oxide coating of the 3.5 "barrel always shows slight color shifts, highlighting the internal structure of the aluminum used.
The raw tubes are stress-free annealed before machining - this is necessary due to the extremely tight fit. The resulting changes in the metal structure are formed in the extremely hard titanium oxide coating and can not be avoided.
