Astrophography: What is the down side to using a Field Reducer on a telescope to shorten exposure time?

There are field reducers that will bring an f/10 down to an f/6 or better. This sounds great cause it shortens the time of an exposure but there has to be a down side to this. What do you lose? What is the down side? how far should i take my f/10 down?

Could a black hole be destroyed from outside?

For example, say that a relatively small black hole is in tight orbit around a massive star -- perhaps 30 solar masses. If the parent star goes supernova, would it be possible for the black hole to be destroyed?

If this scenario doesn't work, are there any that do?

Did I see the aurora borealis?

I was on a transatlantic flight, roughly 500 miles south of the southern tip of Greenland. Could I have seen it from there? I took a bulb photo out the window for 30 seconds and saw a very distinct green strip. If so, it was pretty cool!

Accurate distance measurement in universe by speed of light? Impossible....?

I challenge the accuracies of distances measured in the universe by speed of light. We know that nothing is stationary in the universe. I would say the entire universe is spinning itself at the rate beyond our imagination. We believe that nothing moves faster than the speed of light. But, I would say that Universe itself is spinning at much larger speed than the speed of light and that accelerates everything in it. The wall acceleration generates enough gravitational pool inside the universe and provides rate that moves everything inside it. It is possible that the point we are looking as the deep viewing (14 billion LY) of galactic cluster may come closer to us one day, that means Andromeda Galaxy and/or the other neighboring galaxies would move billions of LT away from us.
