I bought my first telescope used. It’s a celestron astroview eq 90mm refractor. When I bought it I saw some dust on the lens. So i took out the objective lens to clean it. However there is a speck of dust that is inside the lens. I can’t clean it off from either side. Like it’s buried in the middle of the lens. Very disappointed and feel like I wasted my money. I have attached a picture. There is a small halo around the speck. Altogether it is about 2-3mm in diameter.
how badly will this affect the performance? And if so, is there any thing I can do about it? Is it that it’s two lenses glued together and somehow a dust speck got sandwiched between the layers?
thanks for your help!
