There are not many reviews on this I guess many just buy the ZWO guidescope. It is really well made and works well with my ASI290 connected to the ASIAIR pro. It also fits perfectly in the Redcat padded case without cutting the foam. It’s light enough to work on my Star Aventurer with the standard counterweight and it’s very easy to set up.

Originally bought the ZWO guide scope, but was unhappy with the quality, and the poor focussing. Maybe I just got unlucky. Anyway, ordered the WO model to replace it, and am a lot happier. Quality feels very nice, with a nice anodised aluminium finish. And the printed measurement on the tube is a nice touch, and will make for easier setup if ever the scope gets packed away. Feels like a premium product for just a little more money than the ZWO alternative. Very pleased.
