Our view

For telescopes with 2" eyepiece fittings, an excellent choice for low power extreme wide-field images. Perfect for the Virgo cluster, M31, the Veil Nebula and the Milky way through Cygnus. 


For the Veil in Cygnus, budget for a 2" Baader OIII filter. The performance of this eyepiece and a UHC or OIII filter of M42 in a well collimated 9.25", 11" or 14" SCT is stunning.
