        Good travel scope or for kids

        Pretty good optical tube and eye piece. But focuser, diagonal and the mount are bargain basement.

        I ended up upgrading the diagonal and put it on a celesteon Omni mount which has slow motion controls.

        Excellent entry level telescope

        Personally I was disappointed in what I bought because my expectations were unreasonably high. Sold my 8” Meade SCT several years ago and saw this as a way to get my granddaughters interested in night sky viewing. She is excited about it but there is so much more out there to see so have decided to upgrade to better equipment probably more for me than for her.
        I would liken this telescope mount to a point and shoot camera. Easy to use and enjoy by almost everyone. The aperture is more than adequate, the head is innovative and allows good control and the tripod is light but sturdy. It includes a diagonal that allow a true picture for terrestrial viewing and no outrageoous claims about 400X viewing. The only thing that would make me increase my rating to 5 stars is a way to lock the telescope’s position in place or increase resistance to allow others to view without unintentionally moving its position. Would give it 4 1/2 stars for doing what it was intended for.

        I haven't had a chance to use it. Have it set up. Just ordered a case for it. Looking. Forward to learning how to use it. How can I add to it? I didn't receive the moon filter


        I received the scope faster than I expected. Delivery time was great. Scope itself is great for a beginner like me. I saw moon and Jupiter with its four moons with this scope, but I immediately realized that magnification was not that great for viewing planets, so I had to order another eyepiece with greater magnification. I wish they included eyepiece with greater magnification. I would have bought a carry-bag had they offered it. Setup was also very easy. Mount is ok. I will recommend this scope and these guys. I will order again from these guys. Great service.

        Excellent scope and service

        I bought one for myself for my birthday. Pretty easy to setup, you can see some really cool images on clear nights. I would recommend getting the deluxe pack- I didnt and my viewing experience is probably the lesser for it. The customer service is excellent as well
