Mini 50mm Finder Scope for Guiding and Searching

The SV198 is a versatile guide scope that offers several key features to enhance your astronomical viewing and imaging experience. Its double spiral fine focusing and pull-out coarse focusing structure provides precise control over the focus, allowing you to hone in on your desired celestial targets with ease.

One of the standout capabilities of the SV198 is its 50mm aperture, which helps to gather more light compared to smaller guide scopes. This larger objective lens results in a brighter and clearer view of the objects in the field of view, making it easier to locate and track your targets, whether you're observing planets, deep-sky objects, or anything in between.

The SV198's design also allows for convenient integration with your main telescope. It can be connected directly to the dovetail mount plate or attached directly to the tripod, providing flexibility in your setup. Additionally, the guide scope can be linked to the main lens barrel, enabling you to mount a camera simultaneously for astrophotography purposes.

Focusing on the optical quality, the SV198 features a fully multi-coated, 2-element/1-group achromat lens design. This multi-layer broadband anti-reflection coating helps to enhance contrast and clarity, while the blackened lens edges further improve image quality by reducing stray light. The result is a crisp, high-contrast view that allows you to appreciate the finer details of your observations.

The SV198's focusing mechanism is designed for precision and ease of use. The dual helical and telescopic focusing system provides a fine focusing stroke of 11mm, with an accuracy of 0.1mm, as well as a coarse focusing stroke of 38mm with a 1mm accuracy. This combination of fine and coarse adjustment ensures you can achieve the perfect focus, whether you're making minor tweaks or broad adjustments.

In terms of connectivity, the SV198 is equipped with a 1.25-inch and T2 interface, allowing you to attach a variety of eyepieces and other accessories. This versatility makes the SV198 a valuable tool for both visual observation and astrophotography, as it can serve as a finder scope, guide scope, or even as a standalone telescope when paired with the appropriate eyepiece.

Overall, the SV198 is a well-designed and capable guide scope that offers a range of features to enhance your astronomical pursuits. Its combination of optical quality, focusing precision, and connectivity make it a valuable addition to any amateur astronomer's toolkit, whether you're just starting out or are an experienced observer.
