A while back I read an article on 'pockets' in the atmosphere that can prevent good seeing in otherwise good seeing nights. I never really put much faith in this until recently. The other night I was unable to locate NGC-6440, a 9.3 glob in Sagitarious but, I was able to see NGC-6445 a 11.3 planetary that is just a low power eyepiece view away. The next night, no sign of the planetary and the glob was bright.
I thought I've had this problem in the Virgo cluster also, but I just put it off to being tired and lost.
Am I in the pocket or is this my grey matter ageing?
