Description
Specifications

Used Sharpstar Z4 telescope. There is a tiny tiny spec of dust between the lens.

According to the users’ and market demands, Sharpstar has newly launched an integrated astrograph—Z4. It has an aperture of 100mm and the focal ratio is f/5.5. Z4 is a sextuplet astrograph with three pieces of lens at the front and three pieces at the back, and two of them are ED glasses. Just like other series of Sharpstar astrographs, Z4 is designed as self-flattened so there is no need to calculate the back focus. You can just make the target stay at the focus, and the optical system is perfect for imaging.
