Customer reviewsDefinitely not good for viewing the Stars
I was going to use this for watching dolphins and whales it is much too shaky for handheld and and the tripod it comes with even if you set it up level it up it has a jerk to the twist it doesn t moves easily at all I would rate it at 3 stars I would have returned it but we were in the process of moving in the box got thrown away somehow so I m keeping it eating the loss I am sure there are better ones out there
