Is SESTO SENSO 3 SC compatible with my SC type telescope?
Is SESTO SENSO 3 SC compatible with my SC type telescope?Many Schmidt-Cassegrain telescope owners contact us asking whether the SESTO SENSO 3 SC robotic focusing motor is compatible with their optical tube. SESTO SENSO 3 SC is the focusing motor for SC type telescopes with internal focuser we specifically developed for Celestron and SkyWatcher models to provide a precise and reliable motorized solution. Compatibility depends on two essential factors: the diameter and shape of the he internal shaft of the focusing mechanism, and the rear-cell geometry, which must allow correct installation of the adapters included in the SESTO SENSO 3 SC box. In this article, you will learn exactly how to verify both aspects. We explain how to measure diameter of the internal shaft of the focusing mechanism (21 mm or 12 mm), and which optical tubes the system...
Is SESTO SENSO 3 compatible with my external focuser?
Is SESTO SENSO 3 compatible with my external focuser?SESTO SENSO 3 for external focusers is designed to work with the focusing systems typically found on refractors and Newtonians, including Crayford focusers, Rack & Pinion focusers, and similar mechanical designs. So, if you want to know whether SESTO SENSO 3 for external focusers is compatible with your telescope, the first and most important requirement is that your focuser must include a fine-focus mechanism. If your telescope has only a single direct-drive knob without a fine-focus reduction, SESTO SENSO 3 for external focusers cannot be installed. Once this requirement is met, the next step is to check the diameter of the pinion shaft, which you expose by removing the fine and coarse focus knobs. Let’s look at the procedure in detail.
Telescope focusers: choosing the best motorized solution between SESTO SENSO and ESATTO
Telescope focusers: choosing the best motorized solution between SESTO SENSO and ESATTOHigh-quality telescope focusers are essential to achieve perfect focus, whether you use your telescope for astrophotography or visual observation. To help users upgrade their focusing performance, PrimaLuceLab developed two advanced motorized solutions: SESTO SENSO 3, our robotic focusing motor that enhances the telescope’s existing focuser, and ESATTO, our complete robotic focuser that replaces the stock unit with a high-precision, high-load-capacity system. While both families share the same premium electronics and control ecosystem, they differ in mechanical design and capabilities — making each one ideal for specific telescopes and applications. In this article, you’ll learn how the SESTO SENSO 3 and ESATTO compare, and how to choose the best motorized telescope focusers for your...
