The Touptek PAPO GS-250AR is a high-quality guide scope designed specifically for astrophotographers. Its three-element APO optical system effectively reduces chromatic and spherical aberration, delivering colour-free, pinpoint star images all the way to the edge of the field of view. Its corrected image plane is particularly important for demanding astrophotography applications.
The Touptek PAPO GS-250AR can be used not only as a guide scope, but also as an astrophotography telescope, making it a versatile tool for astronomy imaging enthusiasts. We recommend using sensors with an image circle of up to 16 mm, as larger sensors may show vignetting. The 250 in the product name refers to the telescope's focal length: it features a 250 mm focal length and a 50 mm objective diameter.
The product is lightweight, weighing just 0.82 kg, making it easy to transport and set up. It is also well suited for expeditions, where keeping weight to a minimum is particularly important.
On the camera side, it features a standard T2 connection, while also accepting cameras with a 1.25" barrel, ensuring broad compatibility with different camera types. The f/5 focal ratio is ideal for astrophotography, enabling efficient light gathering.
The focuser uses a rack-and-pinion system with helical teeth, allowing exceptionally smooth, slip-free focusing. Another advantage is that it can be fitted with either the ToupTek AAF or the ZWO EAF focusing motor.
The Touptek PAPO GS-250AR can be mounted in a standard finder/guide scope shoe or attached via a standard 3/8" tripod thread, providing a stable and reliable connection. This product is an ideal choice for anyone looking to capture professional-quality astronomical images with a compact and cost-effective instrument.
