Peter:
I have a few guiding runs but none long enough to get a meaningful FFT.? Weather has been dreadful but hopefully in the next few days I can grab a few unguided worm period's worth.? If the 80s still lingers, I can live with that since even the 32s in the Losmandys can be handled reasonably well with 1 - 1.5s guide exposures and keeping the aggression low-ish.? I'm seeing things <9.6s, but will be more illustrative once I have some data to share.
Keith??
