I guess that they actually
are interested, out there in cyberspace, judging from the number of views. But it would be nice to hear from some knowledgable "deep imaging" practitioners (Ken Crawford springs to mind)
I hope that you do succeed in reliably bringing up details at fainter than 30 V magn. per sq. arcsec.
The fact of the matter is that most of the existing surveys for Low Surface Brightness objects and features have actually been v
ery limited in their depth, due to inevitable constraints on Large Telescope time.
(a lot of discoveries of L.S.B. objects, such as the ultra-faint dwarf galaxies around the MW, were made with SDSS imaging data, which is not what anyone would call deep)
Even the new generation of (> 10,000 sq. degrees) Sky Surveys, as typified by SkyMapper Southern Sky Survey(
http://rsaa.anu.edu.au/research/proj...ern-sky-survey ) and the VISTA Hemisphere Survey (
http://www.vista-vhs.org/ ) and the Large Synoptic Survey Telescope, will require
very multiple passes of the same field, taken over many years, to achieve deep images of various fields.
In fact, the new-generation Sky Surveys are specifically
not optimized for depth! (bizarre, but true)
Therefore, I think that there is room for amateurs to make a serious contribution in the area of ultra-deep imaging of galaxies and inter-galactic objects.
