Description
These 5 & 6 element eyepieces have exceptionally Flat Fields of view with wide fields from 53 to 65 Deg.
These eyepieces are well-engineered with a buttery smooth pop up eyecup mechanism and single-piece anodised alloy housing.
This complements the good eye relief across the range of eyepieces.
The images are of a 16mm eyepiece (our personal favourites at Night Sky Secrets) with the design being typical across the range.
The 16mm is a great eyepiece to try out as it fills the gap between the 10mm and 25mm Plossl supplied with most telescopes and will show you just how much difference a high-quality eyepiece can make to your view of the night sky.
The following table shows the specifications for each eyepiece. Choose from the pulldown menu to selects the focal length required. Specifications for Ultra Flat Eyepiece
