: I bought my son a tasco telescope for christmas but unfortunetly I think it is to cold to observe any thing for a short period of time. Is it possible that the lenses or eyepieces are frosting up or did I just by a lemon? Any help would be appreciated. ***You have dew building up on the optics, usually this disappears after scope cools down to outside temp. our you will get a dew buildup as the scope sits outside during the night as it will on all surfaces, the Tasco is a cheap scope but no lemon I have had a chance to test a 60mm model recently and though the mount is poor the optics were quite good for the money, I could clearly see the cloud belts and moons of Juipter, the rings of Saturn, and much detail in the Orion nebula, the Andrometer galaxy and other brite galaxies like M81 and M82 look great as do many star clusters like M13, plus endless detail on the moon, just remember to use low power and donot use the barlow lense...
