The Starfield f/4 Imaging Newtonian is a fast, large-aperture reflector specifically designed for deep-sky astrophotography with APS-C DSLR and dedicated astronomy cameras. Built with a thermally stable BK7 primary mirror featuring protective SiO2 quartz coating and a 4-vane spider secondary, the telescope delivers excellent contrast through its matte black interior and extended tube design. The dual-speed monorail focuser with 10:1 reduction provides precise focus control for imaging payloads, while six collimation knobs with a marked mirror center enable quick laser collimation. This fast f/4 design produces approximately 2 degrees of field of view diagonally with APS-C sensors, making it ideal for wide-field imaging of extended objects like the Orion Nebula and Andromeda Galaxy.
