    Great Optics at Little Cost

    This little scope is a gem! After making some changes to the lightweight tripod to make it sturdy it works great. I was really surprised at the wide-field views and 100 plus power on the crescent moon. There is some CA, but I did not find it objectionable. It's worth the money and does more than I paid for.
