ToupTek HOPE D60

The ToupTek HOPE D60 is a 60 mm f/4.66 apochromatic astrograph with a built-in field flattener. Its five-element optics give a 44 mm image circle, enough to cover a full-frame sensor without a separate corrector.

At 280 mm focal length the field is wide. A full-frame sensor covers about 7.4° × 4.9°, and an APS-C sensor about 4.8° × 3.2°. With 3.76 µm pixels, as on the IMX571 in many APS-C cameras, it samples at 2.8″ per pixel.

Back focus

The camera thread is M48 × 0.75. Set the sensor about 55 mm behind it. ToupTek gives a working range of 50–58 mm, and 55 mm is the place to start for round stars in the corners.

Rotator and tilt

The telescope comes with ToupTek’s RotaTilter fitted and aligned at the factory. You can turn the camera to frame a target and read the angle off a scale, so the framing can be repeated on another night. Four screws square the sensor to the light path, and the tilt holds as the camera turns.

Focuser and size

The 3″ dual-speed rack-and-pinion focuser holds a full imaging train, and takes a motor focuser such as ToupTek’s Astro Automatic Focuser.

The tube is 255 mm long with the dew shield pushed in and weighs 2.83 kg, so it suits a small mount and travels easily. It’s made for cameras, not for visual use with a star diagonal.
