Automated GoTo mounts transform the telescope experience — instead of spending half the session hunting for faint objects, you queue up a target list and the mount does the navigating. But most GoTo packages under $1,000 pair the automation with undersized optics that can't actually show you the objects the mount finds. The Explore Scientific Sidara Pro 102 changes that equation with 102mm of refractor aperture on the Sidara Pro GoTo mount, providing both the automation to find objects and the optical performance to reveal them.

The 102mm doublet refractor at f/6.5 collects significantly more light than the 80mm class, pushing the useful catalog of observable objects well beyond the Messier list and into the NGC. Wide-field sweeps of the Milky Way at low power show dense star fields and open clusters with real structural detail. Switch to higher magnification, and the unobstructed refractor aperture delivers lunar and planetary contrast that reflectors of the same size cannot match. The 2-inch focuser accepts a full range of modern eyepieces, from narrow-field planetary oculars to ultra-wide deep-sky eyepieces.

The Sidara Pro GoTo mount handles the navigation. Select targets from the hand controller or SkyAssist smartphone app, and the mount slews and tracks automatically. Battery power keeps the entire system portable for field use without AC access. The combination of GoTo automation and a 102mm refractor means you can realistically observe 50 or more objects in a single evening session — a pace that manual star-hopping simply cannot match.

Key Features

• 102mm doublet refractor at f/6.5 — versatile aperture for both planetary contrast and deep-sky light gathering
• Sidara Pro GoTo mount with automated slewing, tracking, and SkyAssist smartphone integration
• 2-inch focuser supports both 1.25" and 2" eyepieces and accessories for future upgrades
• Hand controller + smartphone app for dual-method target selection and tracking
• Battery-powered for portable field operation without AC mains
• 90° diagonal and cradle rings included for comfortable viewing and flexible OTA positioning

Ideal For

Visual observers who want automated convenience paired with enough optical performance to make it worthwhile. The 102mm aperture is the practical minimum for productive deep-sky visual work through a refractor, and the GoTo mount means every minute is spent observing rather than searching. Outreach coordinators and star party hosts will find the GoTo automation invaluable for moving between crowd-pleasing targets quickly. Beginners who prefer technology-assisted learning can build sky knowledge by watching the mount navigate to objects they select from the app's curated lists.
