Zenithstar 73 III is a greatly versatile and portable refractor telescope for beginners and veterans alike. Designed for both astrophotography and wildlife photography, high power visual observing through the Zenithstar 73 is also hugely satisfying. The image is crisp, sharp and color aberration free thanks to the use of top quality glass — FPL-53. The 43mm image circle when Flat73 is used covers a full-frame size sensor nicely.
