I was impressed with the quality. I have an old Tasco 4.5 f900 and it never looked so good. Maybe I’ll get the 7.5 next.
I recently purchased an Antares 25mm Plossl eyepiece from OPT and I was glad to find .965 eyepieces. I use the 25mm with my C-90 spotting scope and decided to buy the 12.5mm to double the magnification. I have been pleased with both eyepieces and feel they provide good quality for the price. I would definitely recommend the Antares eyepieces and I enjoyed doing business with OPT.
I am glad to have found these Plossl eyepieces in the .965 size as I have a nice old 60mm refractor that I have had for 50 years and these are much better than the original Huygens eyepieces that came with it. I also got some inexpensive TPO plastic cases for protection. Thanks for helping to bring some new life to my classic old scope.
I recently stumbled upon at 60mm Unitron refractor from our astronomy club attic sale. It's a post WWII Japanese manufactured telescope for the American market. It is beautiful piece of work - optics, GEM mount with beautiful machining and gears and teak legs and boxes for scope and mount. It's in my family room picture window. It had original eyepieces and I wanted to see what some new Plossl's would do for it. It is hard to find new 0.965 eyepieces. An adapter ruins the clean look of the scope. OPT had reasonably priced Antares 25 and 12.5 mm eyepieces and they add some clarity beyond the original equipment eyepieces. I will use OPT in the future.
Love this eyepiece. Good .965 are hard to find. Would buy more.
