Excellent eyepiece

Review by V. V. on 21.06.2023 11:22:31

( 5 / 5 )

APM Zoom easily replaced my two trusty Baader Hyperions, 17mm and 13mm (tuned to 10.5mm). Image sharpness is equal, if not better, and color rendering is more neutral when compared to "yellow" hue of Hyperions. Also, it is very convenient to adjust magnification according to observed object, and 7.7 to 15.4mm range is very useful. I can notice some coma with stars that are not in the center of field of view, but that is probably due to my telescope (300mm F/4.9 Dobson) and not eyepiece's fault.
