Its a theory, really, based on the recent cleaning of the primary and that I had thought I had collimated it OK, but it may just be some dodgy subs with eggy stars, I noticed some northwest, southwest elongation of the stars, so I am thinking that....
haha i got a chuckle out of that. Good to see you could still image in the end.
Dew and collimation are two big areas i still need to address for my 8" blue tube. one day...
