Spiral versus Ellipse in Virgo

That's clealy put, Mike. I think I understand better now. When used even more recklessly, wavelet sharpening and decon in particular can produce what I call a "glassy" look - high contrast but nothing to do with what's up there. We try to stop short of that, because it's pretty ugly. But I think you're saying, quite reasonably, that one should stop even further short.

Is it possible to use subtle sharpening or local contrast enhancement without either putting things in the image that aren't in the sky, or taking out of the image things that are really there?

Beautiful field there Mike and Trish. Regarding decon. My test for the right amount of decon is that Mike S fails to comment on it.

Beautiful shot M&T. Plenty of background galaxies to keep the viewer engaged.

A lovely image MnT. I enjoyed swimming around in the large version, so many galaxies, with the two stars being standouts in terms of details.

Well done!

...oh well, we do see less worms and dots these days...

Seriously though, there was a time I recall a fixation on noise levels in images being pointed out in every post reply...but noise is not an intentionally added applied option but rather a function of less than optimal exposure time or over stretching, so IMO at least...it is much less of a processing crime . However, (over) applying a filter to artificially alter the details and completely changing the look of an image, well!..THAT is a serious crime...that needs reporting to the correct authorities!

Wow a really deep image chock full of activity M&T.

I'd call your pic more of an 'Avengers' shot, no single hero in this baby. Love that elliptical, the dust lane teasing the eyes, is it really there? Yes it is!

With all the mosaics out there, why not make it even bigger, do an Avengers versus Justice League battle scene... make me chuckle 'this is a 4 by 4 panel mosaic comprising 23 arcsecs'

Thanks Geoff.

We shall be ever more gentle.

Thanks Simmo.
