While I can't claim the same heroic total exposure time effort as Mike, a quick back of the envelope calculation shows 5 hours with a 14 inch easily gathers more flux than 19.5 hours with a 6 inch telescope....begging the question are there even deeper examples out there?

Actually Peter I didn't say that at all, if you re-read my article I said "...we have what I BELIEVE is the deepest COLOUR image ever taken of this galaxy and its SURROUNDING FIELD"
An exhaustive web search and discussions with both David Malin and Harvey butcher (director of ANU Research School of Astronomy and Astrophysics) showed up nothing..?
Sooooo all your impressive mathematical analysis aside (ie possible in theory yes but has it been done???
)...if you would be so kind as to please show us all a deeper version I for one would love to see it. That doesn't mean there isn't one out there but it sure is hard to find....
hence my "belief"
