Deepest NGC5128/Cent A?
A tip of the hat to Mike S for his photo-essay in this months AS&T, it was however a comment in the essay that has me thinking...was this "the deepest colour Cent-A shot taken" ?
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?
