Little gem

Actually purchased this 50 mm triplet for a grab n go visual instrument and the optics live up to the name sharpstar ! The moon, Jupiter and Saturn using the televue 3-6 mm zoom were excellently detailed for a 50 mm , greenish Orion Nebula with the trapezium bluish stars were a treat as well as many double stars and bright deep sky objects of the winter sky , love my little gem !
