The Touptek PAPO Guide Scope GS-250 is a high-quality guide scope specifically designed for astrophotographers. Thanks to its three-element APO system, its objective eliminates chromatic and spherical aberrations, providing a color-free and pinpoint view even at the edges. The image plane-corrected imaging is particularly important for producing high-quality astrophotos.
The Touptek PAPO Guide Scope GS-250 can be used not only as a guide camera but also as an astrophotography lens, making it a versatile tool for astronomy photography enthusiasts. It is recommended to pair it with sensor formats up to 16 mm in diameter (larger sensors may experience vignetting). The 250 in the product name refers to the telescope's focal length, meaning it has a 250 mm focal length and a 50 mm diameter objective.
The product is lightweight, weighing only 0.82 kg, which facilitates transportation and installation. It is also well-suited for expedition purposes where minimizing weight is essential.
On the camera side, it features a standard T2 connection but also accommodates 1.25" cameras, making it widely compatible with various camera types. The f/5 focal ratio lens is ideal for astrophotography as it allows effective work under low-light conditions.
The focuser has a helical rack and pinion system, enabling very fine, slip-free focusing adjustments.
The Touptek PAPO Guide Scope GS-250 can be mounted in a standard finder/guide scope shoe or connected via a 3/8" standard tripod thread, ensuring stable and reliable attachment. This product is an ideal choice for those who wish to capture professional-quality astronomical images with minimal investment.
