This is a very good medium to low power eyepiece for viewing smaller emission and reflection nebulae, open clusters and for resolving stars in many globular clusters.
It can be used for low power lunar observing or even the planets. The rubber grip give sure grip and makes it comfortable to use in cold weather.
The 17mm eye relief makes it very comfortable to use and is a great eyepiece to barlow.
The 25mm TeleVue Plössl was top-rated in a recent test report of 31 eyepieces in Sky & Telescope magazine as being the best in its focal length.
Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.
