I've been an amateur astronomer for a while now and have a couple of telescopes both of which are pretty bulky. I also had a pair of 10x50 bins which are highly portable of course but with only 10 magnification and not a lot of light gathering ability, they were never going to show much detail. I bought these as a grab and go for when you just want to have a quick look at Jupiter and its moons or a scan of the lunar surface. At the price, I was only expecting something that was a bit better than my 10x50s but wow, the viewing through these is terrific and I hadn't quite appreciated just how much better they would be. The moon is a joy to view through these, they are very easy to focus and have an excellent quality feel to them. The tripod mount adapter is pretty wobbly to be honest but that's not the real purpose of these. If you're in the mood to set up tripods then get an astroscope but these are small and light enough to hold without any problems.
I really am very very pleased. Another brilliant low cost item from Celestron.
