Sharpstar 50EDPH 50mm Aperture F5.5 Portable Professional Astronomical Telescope with Retractable Lens Hood

Sharpstar 50EDPH 50mm Aperture F5.5 Portable Professional Astronomical Telescope with Retractable Lens Hood

Description:
- The 50EDPH is an OTA with a 50mm aperture, 275mm focal length, and f/5.5 native focal ratio.

- The 50EDPH is compact and lightweight, with a gross weight of 1.0kg (including the dovetail plate) and a total length of 196mm.

- With excellent optical quality, user-friendly mechanical design, and a size that can be grasped in one hand, the 50EDPH is a perfect choice for daily observation and shooting.

- The 50EDPH is a triplet air-spaced APO design, including two pieces of ED glass. The triplet design is rare for a telescope of such a small aperture, and the chromatic aberration control is exceptional.

- The 50EDPH has a retractable lens hood to further shorten the overall length and increase portability.

- The 50EDPH has a 70mm Vixen-style dovetail plate, which slotted 1/4-20 threaded holes, making it not only adapt to most equatorial mounts but can also be mounted on a tripod for use.

- Before the focuser, 50EDPH design a 360° rotator, which is also equipped with a rotator locking screw.

- The 50EDPH's focuser is a dual-speed rack and pinion rigid focuser, with a 1:10 precision fine adjustment knob and an overall travel length of 60mm.

- The rear end of the 50EDPH is equipped with a 1.25" adapter, which can attach a 1.25" diagonal and eyepiece for visual observation.

- It is worth mentioning that the 50EDPH also comes standard with two sections of 5cm M48 extension tubes. The extension tubes can be connected to the eyepiece for visual observation instead of the diagonal, or to a planetary camera for planetary imaging.

Sharpstar F4.6 0.84x Reducer High Quality Astronomical Accessory Dedicated for 50EDPH Telescope

Description:
- The 0.84x reducer can bring 50EDPH's focal ratio down to F4.6. This is a standard reducer with field flattening capabilities as well. A shorter focal ratio allows the OTA to have a wider field of view and faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, and faint, fast-moving celestial objects.

- The 0.84x reducer adopts a quadruplet design and supports an APS-C frame. The overall weight is 0.24kg. The back focus from the M48 thread is a standard 55mm. The front thread is M42x1 and the camera end thread is M48x0.75. At the same time, it has a built-in 2-inch filter thread, which can be directly installed and used. The overall CNC machined, both end threaded metal caps prevent ash when not in use.

Specification:
- (After attaching) 50EDPH Focal length: 230mm
- (After attaching) 50EDPH Focal ratio: f/4.6
- Lens number: Quadruplet design
- Back Focus: 55mm (from the base of M48 male thread)
- Weight: 0.24kg
- Rear-end thread type: M48x0.75 (M48x0.75 filter thread inside)

Package Included:
- 1 x Reducer
