Being a fairly casual observer, but having some nice views from our attic room, I fancied getting some binos that I could use both terrestrially and astronomically. I wanted something with a bit of power (I already have a set of 10X50s) and with big lenses for light grabbing. The Celestron's were attractive at the price so I gave them a whirl.
These are big, but solidly made, with a nice rubber finish which gives a good grip. A tripod is clearly going to be needed for anything other than a quick glance around, but they sit pretty well on my medium-duty tripod using the inbuilt, and adjustable tripod adapter - I just screwed in a quick-release plate for my tripod with a standard sized screw and away we went. Adjustment is easy and the bracket allows for adjustment of position as well as the tripod.
Views during the day are fantastic and clear and give a nice crisp view. There is some CA on brighter objects, but not enough to upset me. I have not had much chance to use them for astronomy, although views of the moon are again crisp and clear. CA can be more of a problem at night and a couple of times it was quite bad on a bright full moon - I am not sure if this is the same for all models in this range, or if I need to set them up better, as I have read other reviews that don't see it as a problem, but it is worth noting. I think careful set-up and patience will be required at night, but I was still able to get a decent view of Jupiter's disc and moons, despite it rising next to a full moon a couple of nights ago.
Weight-wise, they are not as heavy as I imagined but, again, you will need something to mount them on as your arms will get tired very quickly - once focused it is easier to hold them closer to the objective lenses and let the eye-cup rest against your eyes but, again, you won't be doing that for long periods.
The supplied bag and strap are simple, but fine for basic use - if you are planning on taking them out and about a lot, then you might want to invest in a more solid strap and a hard case.
As a "starter" set for casual viewing, I think these are a great buy. If you are more "serious" user and want something devoid of CA, then you will need something a lot more expensive - for the price, the Celestrons give a pretty decent bang for the buck.
