Very pleased with these binoculars ! Many thanks to Harrison Telescopes for such brilliant service. The binoculars arrived at warp speed 24 hrs after placing my order. They are awesome and great value for money. Tried them last night with bright sky (near full moon). Easily saw M57 in Lyra, M13 in Hercules. Can't wait for dark nights.
