I wasn't aware of using the 400F for deep sky work.  Thanks Sean for pointing John's images out.  I was aware he had been using 100F on planetary nebs.

Chris,

 

   Isn't it Provia 400 F that is all the rage right now in Japan for deep sky work? Has anyone tried this out for deep sky with a telescope?
