Regards Simon.

You buy a telescope, to you, its a telescope and the clouds will form heavier and heavier as the package gets closer to your door. However, to me, your scope is an "atmospheric dispertion corrector" as my old clouds are now your new clouds......thank you, and enjoy the clouds...... ...actually never heard of an "atmospheric dispertion corrector", sounds like a Klingon disrupter on full power.

So you won't see the red/blue bands anymore, but I do have my doubts that this will result in a much sharper image.

Is this a filter, like a UHC filter to filter out light pollution?

Never tried it myself but there are some good examples to be found in German forums.

It did improve the view of planets below say 40 degrees in altitude. That extended that time we could observe, and was most helpful during the summer, when planets never get too high in the sky from 42 degrees north. Alas, he misplaced the gizmo, so it’s all ‘history’ now.
