The right optics showed a large coma at the left and top edges of the FOV; the rest of the right FOV was OK (Vega being fainter than Venus, which showed some coma when centered). There are pluses and minuses to both, although CF, or Center Focus binoculars are much more popular.In addition, observe more current safety instructions and regulations for the products on the manufacturer's side or the product descriptions and installation instructions on the manufacturer's side. The measurement is in millimeters and is taken from the last lens surface to the point beyond the eyepiece where all the rays of light come to focus and form a sharp image. Depending on the existing equipment of the machine, this can result in the use or purchase of additional components. I focused the view to my left eye and then used the diopter adjustment on the right eyepiece to bring its view into focus. The approved adjustment for the concrete screws allows the screw to be unscrewed twice to align the attached part, and then to tighten the screw again.
