Thats a bit odd. If it was a planet you could imagine missing it or the change in focus making it invisible, but now that I think about it having the moon dissapear seems unusual. I regularly use 2 and 3 x barlows and do sometimes have problems because of changes in fl but havent had an issue with the moon. Having said that the neximage 5 is the only web cam I have spent much time using. Anyhow - nice moon pic
