Explore scientfic Twilight mount withcelestron-6-150mm newtonian ota
The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.
Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment.
The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum.
