Good purchase - Celestron SkyMaster 20-100x70 Zoom Binocular - Giant Astronomy Binoculars 71012

Bought these for our 11 year old grandson birthday. He loves astronomy. Thought would be a good start before advancing to a telescope. I will say I have difficulty focusing them at night, but not during the day. This may entirely be due to not having the best eyesight. My grandson, though has been having a great time with them. Has done some great watching of the moon, is spending all kinds of time outside with his sister and dad, trying to find different planets, etc. Overall a very good purchase.
