The 100 - 110 degree Stellarvue Optimus Eyepieces are now for sale on our website. Performance matched other extremely wide angle eyepieces but ours are either lighter, require less balancing than some or are much less expensive. These are sealed to prevent moisture from seeping in under normal viewing conditions. We are using a very expensive grade of rubber in the grips and eyecups so they last longer than many other import eyepieces. All of the changes and mods we did were designed to optimize the handling and performance of 100 - 110 degree eyepieces.  We are very pleased with the results of our efforts.
