The Zenithstar range is the most versatile and portable scope ever made by William Optics. The ZS61 II APO features an air-spaced doublet lens with fully multi-coated optics and an Ohara FPL-53 ED glass element for sharp, high contrast images virtually free of false-colour.
It provides high resolution images when used for astrophotography or wildlife photography and is a convenient ultra-portable telescope for visual astronomy.
The fast f/5.9 focal ratio and compact size make it ideal for convenient wide field astrophotography or piggybacking. These telescopes can be used for high power visual work, as well as lunar and solar photography thanks to the dedicated Flattener 61. It is truly a great piece of optical engineering.
Convenient rotatable L mounting bracket for easy framing of target.
CNC machined aluminium for a superior fit and finish.
Dual speed 2" 1:10 R&P focuser.
Available in Red, Gold or Space Grey anodised.
