Tripod head with fine adjustment for quick and precise polar height adjustment of the BRESSER StarTracker astrophotography mount PM-100. The BRESSER tripod head with fine adjustment MH-100 allows for very precise adjustments using large knurled screws. To keep the adjustment paths via the knurled screws as small as possible, the mounting plate features a quick-release mechanism with gearing, enabling a coarse pre-setting of the polar height (latitude at the location). The MH-100 tripod head can be mounted on any photo tripod with a 1/4 inch photo thread. The StarTracker astrophotography mount can then be attached to the MH-100 tripod head without the use of tools via a photo thread screw (1/4 inch). The entire tripod head is made of black anodized aluminum, ensuring maximum stability through the use of solid material. The knurled screws with fine threads are even made of stainless steel, guaranteeing long durability and corrosion resistance. Ideal for optimizing tracking accuracy in astrophotography. Note: It can also be used as a stable adjustment element for a guide telescope in astrophotography. This allows for quick and precise parallel alignment of the main telescope and guide telescope. Base plate connection: 3 x 1/4 inch photo threads with a hole spacing of 35.0 mm. Mounting plate connection: 2 x M8x1.25 threads with a hole spacing of 35.0 mm.
