Celestron adapter does not work with some Celestron binoculars.
on July 23, 2017
Will not work if you want to use it on a solar binoculars to look at the sun. When you aim too high, the tripod will be in the way getting your head in position to look through the binoculars. During the eclipse, you will have to aim very high, so this will not work with solar protected binoculars. The other big issue with this is that the screw is very short so that it only screws in less than one turn into my binoculars (Celestron EclipSmart 10x45 Solar Binocular). So if you bump the binoculars too hard, they can fall off and to the ground they tumble unless you are very fast to catch them as they fall. It needs a longer screw!!! Another issue when screwed in, you can't get it tight enough so that it easily always wants to unscrew from the binocular. It needs a lock washer on the screw where it comes in contact with the binocular. But with only less than a turn, a lock washer will take up some of the space making it less than half a turn which means it will likely just fall off. Without a longer screw, this is unusable and unsafe for my binocular investment, even if I was doing horizontal observations instead of vertical. For use of solar binoculars or for looking at the moon with standard 10X binoculars, you will need a tripod as those things are too hard to find in the sky each time you put the binoculars up to look.
