The Zenithstar 61 is designed for both daytime and nighttime viewing, as an outstanding travel scope. We recommend purchasing a WO 2” star diagonal to make the most of these little telescopes. Since the Zenithstar 61 is well suited to viewing nebulae, clusters, large galaxies, and comets, we recommend the use of high-quality wide-angle eyepieces. The WO SWAN, XWA, and SPL series eyepieces are available in a variety of focal lengths. Viewing the
moon and planets is also impressive at magnifications of 120X when the seeing conditions permit. To calculate the magnification of your telescope and eyepiece combination, divide the telescope focal length in mm by the eyepiece focal length in mm. Keep in mind that the atmosphere plays an important role in seeing conditions, and only the best-seeing conditions will support high power viewing. Additional power under less than ideal seeing conditions will not result in an increase in viewable details, and lower powered eyepieces should there be used under those conditions. It’s easiest to locate objects using low-power eyepieces (20X magnification) and then zoom in by switching to higher powered eyepieces. The largest field of view will be seen using a 12x low power-wide field of view eyepiece.
A stable tripod or mount is recommended for optimal viewing. This includes high-quality photography tripods, and German Equatorial mounts, which are designed for astronomical use and include precise tracking of celestial objects. Optional accessories from WO include mounting rings and plates, super high quality 2” Quartz star diagonals which provide for superior viewing and high-quality images. The Zenithstar Telescopes are suitable for large-field astrophotography; Zenithstar 61 has a great color correction at a fast speed of f5.9.
