Bought a pair of these hoping I would get lucky and get a good pair. Turns out I didn't and went through the manufacturer for warranty. 2 months old and have to pay $25 warranty fee plus shipping fee and then had to return them 4 times at their cost and 5 months later have the replacements that are worse then what I had started with. Problems with them is double images when you zoom and the replacements had the same issue and now included rainbow colors. Just gave up on them ever giving me a good product replacemnt. Don't buy celestron if you don't want to waste money.
