As seen on the RedCat 61 series, the patented William Optics Internal Focus Design (WIFD) makes its debut on the RedCat 51 series! The addition of the WIFD system brings something that RedCat 51 fans have all been waiting for: out-of-the box electronic focuser compatibility. This innovation from William Optics provides the ultimate Apochromatic refractor for astrophotography!
This internal focusing design does not shift the length of the OTA in any way, as the optics themselves move within the telescope as opposed to the camera moving. This prevents vignetting seen with traditional rear mounted focusers, and allows for a better redistribution of weight for improved balance of your optical assembly during your night of imaging. This WIFD apparatus offers the ability to automate your astrophotography set up with an electronic automatic focuser as well! When pairing this innovative technology with the high quality Petzval design of the RedCat series, William Optics delivers a telescope with outstanding astrophotography performance.
Designed to be the best, affordable, small, lightweight and fast Apochromatic refactor for astrophotography. The unique optical design includes the highest quality glass for the best possible color correction and flat large image circle. The result is a 51 mm objective lens, in a sleek Petzval design, for a full-frame image.
