The
Starfinder Dobsonian Mount:
Meade Starfinder Dobsonian mountings provide for smooth manual
motions of the telescope in both altitude and azimuth. Both
telescope axes ride on low-backlash Teflon/Nylon bearings, facilitating
the location and tracking of celestial objects anywhere in the
sky. Each mount is manufactured of cabinet-quality materials
and designed for a lifetime of use. Handles are provided for
easy portability.
Spiral-Wound
Optical Tubes: The Sonotube™ optical tubes of Starfinder
reflectors have excellent insulating characteristics, so that
thermal tube currents are reduced to an absolute minimum. While
the smooth white finish of the tube is not intended to match
the gleaming, hard, powder-coat finish of Meade Schmidt-Cassegrains
and ED Apochromats, it nonetheless instills a solid pride-of-ownership
in any Starfinder owner. |
