Hi Ken, thanks for the reply, i assumed that it had been a bug at sometime, thats what i meant by resolved!
for me the point was that it never happened in the previous version noted above...i have not changed anything in my mechanical set up since loading the latest beta today, hence my query....
i do know that my focus is good despite the warning and im happy to ignore it but it is clearly worth the discussion, i have just completed a run of 7 hours, on the rarest of clear nights, i cannot complain can i?
this software is without doubt superb 
after chatting to my friend, he suggested that it may be related to the seeing conditions, i dont fully accept that but it is a fact that my seeing earlier was terrible, i wish i had tried or been here when it had improved but bed called whilst it ran..
just seen your request for the focus packs...uploading now.it will take a while so ill comlete it later.
regards Ray
