William Optics RedCat 71 First Look

The William Optics RedCat 71 represents the next step forward in the evolution of the RedCat series, offering greater reach, improved optical illumination, and a noticeably more capable imaging platform compared to the smaller 51 mm model. This first-light session highlights what it feels like to take the RedCat 71 out under the night sky for the very first time, from setup to initial star tests and early deep-sky exposures.
