The Sharpstar 76EDPH F/4.5 is the latest development in dedicated full-frame focal reducers. Designed to work with the Sharpstar 76EDPH apochromatic refractor, this 0.8x reducer and flattener meets the needs of demanding astrophotographers who use cameras with up to full-frame sensors for wide-field deep-sky imaging.
This focal reducer features a triplet air-spaced structure and large optics that achieve excellent field flatness and illumination over a 44mm image circle.
One end of the reducer features a M74×1 thread that connects to the pinion focuser. The other end uses a M48×0.75 thread to attach to the camera or a 48mm T-ring for a DSLR. The focal plane is 55mm from the end interface.
The reducer also features a built-in 360-degree rotator that allows you to easily rotate the camera to achieve the best image framing. A internal M48x0.75 female thread allows the use of standard 2" filters.
- Use for telescope models: Sharpstar 76EDPH
- Reducing focal ratio: f/4.5 (0.8x)
- Image circle: 44mm
- Lens type: Triplet
- Largest diameter: 88mm
- Back focus: 55mm
- Total length: 77mm (including M48 thread)
- Surface coating: Fully Multi-Coated
- Weight: 0.5kg
This reducer can also be used with the 94EDPH telescope with good results, although its performance will not be as good as with the 76EDPH telescope.
