Explore Scientific Twilight I Adjustable Angle Alt-Azimuth Mount

A long refractor on an alt-azimuth mount can run out of clearance before it points straight up. The Twilight I's head tilts 45° forward or back to give the telescope room at the zenith, and worm gears on both axes, turned by slow-motion cables, handle the fine movements.

Key Features

• Adjustable-angle head. Tilts 45° forward or back for clearance when pointing at the zenith.
• Worm gears on both axes. The slow-motion control cables end in oversized knurled knobs that are easy to turn with gloves on.
• Controls on either side. The cables attach to either side of each axis, for right- or left-handed observers or to suit a refractor or a Newtonian.
• Steady stainless steel tripod. Adjustable legs on a 42-inch footprint, and a spreader accessory tray that locks against the inside of the legs to keep vibrations to a minimum and holds eyepieces between views.
• Powder-coated aluminum head. 6.6 lb; the tripod weighs 11 lb.

Ideal For

• Small to medium refractors such as the AR102, ED102 and ED80, and lightweight, fast Newtonians, up to 18 lb on a Vixen-style dovetail bar.
• Observers who spend time near the zenith, where the tilting head gives the tube room.
• Cold-weather observers who adjust with gloves on.
