The Touptek PAPO GS-200AR is a high-quality guide scope designed specifically for astrophotographers. Its three-element APO optical design effectively eliminates chromatic and spherical aberration, delivering color-free, pinpoint-sharp stars even at the edges of the field. The corrected image plane is especially important for demanding astrophotography applications.
The Touptek PAPO GS-200AR can be used not only as a guide scope, but also as an astrograph lens, making it a versatile tool for astronomy imaging enthusiasts. We recommend pairing it with sensors up to 16 mm in diagonal size (larger sensors may show vignetting). The 200 in the product name refers to the telescope’s focal length: it features a 200 mm focal length and a 40 mm objective lens.
The unit is lightweight at just 0.68 kg, making transport and setup easy. It is also well suited for expedition use, where keeping weight to a minimum is essential.
On the camera side, it features a standard T2 connection, while also accepting 1.25" cameras, ensuring broad compatibility with a wide range of camera types. The f/5 focal ratio makes it ideal for astrophotography, allowing efficient imaging even in low-light conditions.
The helical rack-and-pinion focuser provides extremely precise, slip-free focusing. Another advantage is that it can be fitted with the ToupTek AAF or ZWO EAF electronic focuser.
The Touptek PAPO GS-200AR can be mounted in a standard finder/guide scope shoe or attached via a standard 3/8" photo tripod thread, ensuring stable and reliable mounting. This product is an ideal choice for anyone looking to capture professional-quality astronomical images with minimal investment.
