This all assumes the weather cooperates, otherwise I get what I can take. The basis is if its clear, I'm imaging.

Wow 8.5 hrs - that's productive! Is that
all imaging time?
I managed nearly 21hrs (plus flats time) over 3 nights in May 08 for my Deep Cen A and I thought that was good
...The manual focusing, meriadian flips and re-framing etc eat up time (multiple targets would have been much more time consuming). Apart from the odd stroll to talk with other astronomrs and a few 30min kips here and there, I was out with the scope the whole time too
My recent fighting dragons image was another 6.5hr 6 filter (plus flats) deep image in one night...but sheesh, it is a challenge...I envy your obs and PME
