The complete ZenithStar 61 II: flattener and guidescope included
This performance of the William Optics ZenithStar 61 II It's the complete photo set: the same FPL-53 apochromat, but delivered with a field flattener and UniGuide 32mm guidescope. Unpack, connect your camera, and start shooting, without having to search for loose accessories.
Everything for guided astrophotography
The 61mm FPL-53 doublet with a 360mm focal length (f/5.9) provides a wide, color-pure field. The included flattener brings stars to sharp focus all the way to the corners on any DSLR or mirrorless camera, and the UniGuide 32mm guidescope allows for long exposures on an equatorial mount or star tracker right out of the box. Visual observation is also possible via the 2 to 1.25 inch adapter.
