WarpAstron WARPDRIVE WD-15E Equatorial Mount

•          True output-axis feedback, not just fast correction. The WD-15E builds on WarpAstron's trusted Servo Direct Drive architecture and adds a newly integrated RA output absolute encoder, pairing fast input-side correction with real output-axis feedback so total periodic error keeps shrinking without sacrificing the responsiveness and efficiency servo direct drive is known for.

•          Calibrated, not just assembled. Every WD-15E is individually calibrated using WarpAstron's proprietary process, so the low PE performance on the spec sheet is consistent and verifiable unit after unit, not a lucky sample.

•          Belt-free by design. Dual 14:1 strain wave reducers drive both the RA and DEC axes with true zero-backlash direct drive, so there are no belts to stretch, age, or retension in the middle of an imaging session.

•          Compact head, serious payload. A 3kg head handles 8kg standard and up to 13kg with counterweights at 20cm RA, striking a travel-friendly balance between size and hauling power.

•          Power the whole rig from one mount. Dual saddle ports keep power and data separate, left for power and right for data, with USB-PD up to 100W (12V 5A) on tap for mini PCs, dew heaters, cameras, and anything else riding along.

•          Fast when you need it, quiet when it matters. A 10 degrees per second max slew rate gets you on target quickly, while a gearless, stepper-free direct drive keeps the whole rig smooth and quiet through the night.

•          Ready for the cold. Rated from -25C to 45C, the belt-free build means performance does not fall apart just because the temperature does.

•          Always knows where and when it is. Built-in GPS handles location and time sync automatically, so there is no fumbling with settings under a red flashlight.

•          Layered safety, built in. Encoder-based limit protection, collision detection, and a fail-safe stop keep the mount protected even if a software limit gets missed.

•          Speaks your software's language. Native ASCOM, INDI, LX200, and INDIGO support means the WD-15E slots right into the astrophotography software you already use.

•          A hand controller worth holding. The included 2026 Advanced Hand Controller brings a color OLED touch display with Dashboard, Motion, GoTo, GPS, Power, and Settings apps all one tap away.

•          MSRP: $2,499.
