Smart scope's spinning sensor fights Earth's spin to erase star trails

Draco, DwarfLab's new smart telescope, solves deep-sky astrophotography's oldest headache with a sensor that physically spins to cancel out star trails caused by Earth's rotation. It needs no equatorial mount, no guide scope, and no polar alignment. Just a bigger 90-mm lens and a bet that raw aperture beats miniaturization.

Smart telescopes have mostly competed on convenience: point, tap, and let an app do the rest. What they've traded away is the raw light-gathering power serious deep-sky work needs, since a bigger mirror or lens usually means a bigger, pricier mount to keep it steady. Draco is DwarfLab's attempt to have both. It's the company's first real swing at matching entry-level telescopes on optical power, without asking a beginner to learn what an equatorial mount even is.

The mechanical trick Draco uses to solve field rotation, the slow twisting of the sky's image that causes those star trails, is almost...
