USED - f/5 guide scope
type: Product
description: USED GEAR INFORMATION This guide scope is in great condition. The optics appear crystal clear with no signs of imperfection. There are very minimal cosmetic imperfections on the body of the guide scope. The focuser is smooth and responsive. Description The GS Series guide scopes feature a proprietary three-element PAPO (planar apochromatic with integrated field flattener) optical configuration, incorporating a single ED element to achieve effective chromatic correction. The internal barrel is precision-machined with anti-reflection threads to suppress stray light, while all lenses are coated with multi-layer broadband AR coatings. This greatly enhances image contrast and resolution, ensuring pinpoint star images for accurate, efficient guiding, thus improving the stability of primary telescope imaging. Designed around a 1-inch flat, well-corrected image circle, the GS Series supports sensors up to the IMX533 size. Versatile in function, it can be used for star-hopping, guiding, visual observing, and even DSO imaging—making it an ideal tool for astrophotography, casual stargazing, and entry-level night-sky photography. Key Advantages 1PAPO Apochromatic Optical Design for True Star Color Reproduction The GS Series guide scopes feature a proprietary 1-inch corrected image circle, three-element PAPO (Planar Apochromatic with integrated field flattener) optical design, incorporating an ED glass element to effectively correct chromatic aberration, astigmatism, and field curvature. This design delivers high resolution and crisp, pinpoint star images. The outstanding optical performance makes the GS Series equally suited for guiding, visual observing, and entry-level astrophotography.
