Stop the world I want to get off

Bring back the Icelandic volcano. Clearest skies ive ever seen.

Scientist Chuck Long of Noaa @ American Geophysical Union in San Francisco [bBC Science website] says high flying jet contrails cause an overall haze to the sky that no longer appears deep blue as in the past - would you have thought it!

No mention of astronomers but apparently hazy skies are good for plants/trees in the lower canopy shaded from direct sunlight that now receives partially diffused light for extended lower growth.    The trend has been increasing since the 1970/80s apparently.  

BAN ALL PLANES - do you really need that holiday in Oz?

Recalling how clear the skies were during the no-fly zone/time after the Icelandic volcanic eruptions

Is this not good for us? It sounds like it's letting more light through... Or am I interperating this wrong? :/

If it's a bad thing, I'm glad the plymouth airport closed

I think airports are doing an admirable job of discouraging people to fly.

 I have merged the two threads, as this is being discussed already. (Second thread from Nytecam's #3 post for context)

So many things to make astronomy a difficult pastime for us. Think we all need to set up remote observatories on the the moon...

I had an idea for a station at the L2 point- perpetual night, no LP and 100% transparency... But how would you look through an EP with the space suit in the way?

Sealed, rotating observatory - telescope on the outside, seal point at the Focuser, which would be inside, in the warm...

But surely, if it's a newt or Ritchey–Chrétien you won't be able to change EP as it would break the seal?

Perhapse if there is a coma-corrector fixed in place... That could be the seal and EP/Barlow can go on top?

At any rate, let's not derail this thread, as interesting as this is
