Thanks for that terrific response. Nothing rambling about it. Just very thorough.
I'm usually pretty good about the amount of time I leave the scopes outside to reach equilibrium. Although I've never set them up side by side. That's a great idea and I'll be doing that. I'll let you know how they compare.
Your words have convinced me even more that I've simply not had a night of good seeing so far since Oct 2005. At least not on the nights I've set up to image. Also, Canberra does seem particularly afflicted as far as seeing goes. I'm sure Bird has made comments to that effect.
Persistance. Get out there night after night, if you can. Leave the scope set up and out overnight and do more pre-dawn capture if possible. That's the plan.
But honestly, this lark should come with some kind of warning for your state of mental health
