True, it's not the lens that comes off, only the front adapter - got carried away

It's a pity that the lens it not of better quality. There is quite a bit of chromatic aberration noticeable around the stars when zoomed in, but yes wide field should be all right. It's a great daytime camera though, I took this shot the other day:

I tried some higher ISO settings, but it does introduce a lot of noise. I wonder how bad it would be above the native ISO1600

I will pay around with it some more and see how it goes!
