I have used this for planetary views, works great! Need a little more eye-relief for my glasses. There is a little mark on one corner - just normal stuff – optics perfect and clean! Parks Gold Series Oculars: The Parks Gold Series eyepieces are designed with the latest optical technology and utilize the finest glass available. They offer reduced color fringing, wider field of view, less edge distortions, improved contrast, longer eye relief, and better light baffling than other designs. New they sell for $149.95, I will sell for $100.00 shipped in CONUS.
Thanks – Ken
