The Orion Sirius 8 EQ-G Reflector Telescope fills the bill nicely.
With the GoTo controller, you can command the telescope to swing to any of 42,900 celestial objects selected from intuitive menus on the controller. Dual internal stepper motors then move the telescope at up to 3.4° per second right to your target object, tracking it while you observe or photograph it. With the built-in autoguider interface and periodic error correction (PEC) and an included polar telescope for accurate polar aligning, you'll have an album full of killer astroimages in no time!
