Love the scope but most tripods are to weak to handle this monster.
This scope is one of the brightest I have ever owned. The one major problem I have had is my tripods were too weak to handle it. I have acquired a Regetek RG70A02 from Amazon and all is now fine. The controls on the scope are very smooth and easy to use. The 66-power setting makes 6.5mm holes at 200yds look like 9mm. Couldn't be more satisfied with the scope.

It's a real deal
I can really see mid-sized craters on the moon with this, although I'm primarily using it for 200 - 300 yards range shooting. Either observation, it's very clear with great resolution.

Good price for a mid range scope of known company "Celestron"
Great price for a 100 mm objective spotting scope. Just not as good as my Swarovski 82mm HD for photography. For the price, it was a very good deal.

Solid Buy
Love this product, clear lens, easy to look at sail boats off the coast our mountains in the distance. Slightly more challenging to adjust the focus than on a pair of binoculars or a camera but not much of a downfall
