I'd estimate around 100x is the maximum useful mag for this scope.

So in short, if you want something for low power Milky Way sweeps without burning a hole in your wallet, you can't go wrong with this.

I don't recommed it for planetary observing however as it can't support high powers and chromatic abberation does become a problem.

It won't completely get rid of it, but grab yourself a minus violet filter. You will lose a little bit of light but you'll get rid of a lot of the CA at higher powers.
