Description
Combining a high magnification and oversized objectives, the Celestron 20×50 Ultima Porro Binoculars is an ideal optic for making detailed observations at long distances, even in challenging lighting conditions.
Classic Design
The 20×50 Ultima is a classic Porro prism design that resembles binoculars from years past. As such, the focus wheel is narrow and placed toward the back. By comparison, other Porros I’ve tested have a wider focus wheel more centrally positioned where it can be easier to reach and turn, especially with gloves on.
However, the Ultima’s body is smaller than many other Porros, so reaching the focus wheel is easier, especially with smaller hands. The focus wheel is also rubberized, not hard metal, for a secure, non-slip contact. In sub-freezing temperatures the focuser’s grease did stiffen up, but it was still usable.
