Interesting question Starkler and I am not quite sure, however my scope is normally setup outside with covers on etc. and in this instance, after about a 60 minute exposure to the elements for the scope with covers off, I had a few quick views and was a little dissapointed. Checked against the standard 26mm plossyl and found the plossyl to be slightly better. However, I left the 30mm in, went back inside and checked out the forum, (as one does), and after about another hour went outside to check the views. I have dimmers in the house and was viewing a computer screen, so my eyes were obviously affected by light.
The views were by far superior to what I had previously witnessed. ( I had been looking at Saturn mainly and M42).
So I can only assume that the increased cooling down time had something to do with this, as were my views earlier this morning when observing Jupiter
I believe the other Ken has made the same observation.
