I think the word Turd is a rather exaggerated and perhaps more of a self justifying term really, there are plenty of amazing images out there that weren't compiled from mega data (check some of Leo and Marco Lorenzi's work for example) and may have had some noise reduction or other processing applied, there is a point of diminishing returns here too. To me mega data's real benefit is in surfacing very faint features, so really comes to the for when imaging galaxies or faint nebulae that have otherwise invisible features and perhaps the finest example of this type of work is that by Rolf Olsen, the king of mega data, he has revealed some hither too unseen features with the greatest exposure times of anyone yet he still has some noise in his images.
