William Optics Super ZenithStar 73 Red AP 73/430 OTA apochromatic refractor
The ZenithStar series from William Optics consists of compact but very high quality apochromats, which are ideal for use with a DSLR camera. This enables very good wide-angle images of large star fields. In combination with the optional flattener, these are right up to the edge, resulting in a corrected image field of 45 millimeters in diameter.
The light and compact ZenithStar apo and a DSLR ideally fit a photo mount, such as the Star Adventurer from Skywatcher or the Star Tracker from iOptron - a light and uncomplicated system for astrophotography.
