Product Overview
William Optics Zenithstar 61 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 61 Mark II is also hugely satisfying. The image is crisp, sharp and colour aberration free thanks to the use of top quality glass — FPL53, closely matching the legendary fluorite material. The 43mm image circle when Flat61 is used covers full frame size sensor nicely. The Zenithstar 61 Mark II is tiny in size yet it comes standard with 2" focuser with 10:1 micro adjustment, a rarity for a telescope this small!
