TS-Optics ToupTek Guide Scope with D=45 mm and f=250 mm

TS-Optics ToupTek Guide Scope with 45 mm aperture and 250 mm focal length

One scope with multiple functions - your practical choice

This astro finder / guide scope integrates star finding, guiding, viewing, and photography into a single device. Whether assisting in locating celestial bodies, locking onto observation targets, conducting daily observations, or capturing the beauty of the night sky with an attached camera, it excels at all tasks. This versatility provides users with a convenient and practical experience in one scope.

Exceptional Optics, Precise Imaging
The Finder/Guide Scope features 45 mm aperture with multi-layer broadband coated lenses, ensuring high light transmission and sharpness. This results in finer star points and provides better guiding images.

Sturdy Structure, Flexible Assembly
The entire body is CNC machined from aerospace-grade aluminum alloy, ensuring high-precision fit and structural stability. The primary lens tube features a semi-modular design, allowing the four-section assembly to be freely removed and flexibly adapted to various observation and photography needs. The standard 1.25" interface at the end is compatible with mainstream guide cameras, and by removing the three-point locking screws, it can connect to cooled or planetary cameras with an M42 interface, offering strong compatibility. In this case, we suggest our TST2Rot rotation adapter for aligning.

Recommended to be used in combination with our guide cameras.

Precise Control, Convenient and Easy to Use
