The Sharpstar 50EDPH is a 50mm aperture APO refractor telescope with a focal length of 275mm and a focal ratio of f/5.5 . Thanks to its compact and lightweight design, it weighs only 1.0kg (including the dovetail plate) and measures 196mm in length with the dew shield retracted.
This instrument is designed to offer excellent optical quality , with a triplet APO optics with two air-spaced ED lenses, ensuring exceptional correction of chromatic aberration , a rare feature in telescopes of this aperture.
Main features:
- Dual-speed rack-and-pinion focuser with 1:10 reduction for ultra-precise adjustments and a total travel of 60mm .
- 360° rotator with locking screw , for easy camera alignment.
- 1.25″ rear thread for diagonals and eyepieces for visual observation.
- Double 5cm M48 extension included , for direct connection to eyepieces or planetary cameras.
- 70mm Vixen-style dovetail plate with 1/4-20 thread , for compatibility with most equatorial mounts and tripods.
The Sharpstar 50EDPH includes a 0.84x reducer , which lowers the focal ratio to f/4.6 and also acts as a field flattener. This 4-element reducer supports APS-C sensors , with an M48*0.75 thread for 2″ filters . The standard backfocus is 55mm , with a threaded metal cap for protection.
Perfect for those looking for an ultra-portable telescope for wide-field astrophotography, with sharp images and no chromatic aberrations.
