PHD settings for long FL OAG use
Well, I've bitten the bullet and installed an OAG on the big Celestron 14". I was wondering what PHD settings others have found worked best with long FLs. At the moment, I am setting up to use a big ATIK 11002M (monochrome) at the native F/11 (FL is about 3900 give or take) so guiding needs to be spot on (and everything else too of course).
