DvandenH:
The images are beautiful to see. I am a new guy to celestial imaging, however, I have lots of visual and computer imaging skills. From my lurker's viewpoint I find that the lightened version has lots more bluish white in the central area, however, the structures visible that are green in the former image are not visible in the lightened version. The bluish white image shows a little more at the edges of the structure, and that is always an area of interest to me. I try to see the extent of the object, and I am always suspicious of images of galaxies that have a sudden cut off of light at the outer edges. On the other hand maybe the objects do in fact have a more pronounced boundary edge and do not fade gradually at the greater edges. The bluish white version has better background blacks, and more visible tiny stars, however, all the stars are wider and appear to be slightly out of focus. The bluish white version doesn't appear to be a lightened version with greater visible light intensities. Did you raise the visible intensities of some filtered images and not others? Also, if the bluish white version is slightly out of focus does not that ruin some of the modulations of the lighter lights? My computer graphics card and monitor can display 255^3 possible color hues, and it has [claimed and not possibly actual] 1000:1 displayed steps of contrast. What I often do is to plug in my big high-res CRT monitors that do not have deep blacks and that have lots better faded visible contrast areas than the LCD screen monitors. Ralph Hertle |

Ralph thx for your review,
Hereby a version that's a bit more normalized....the green is OIII lines, the red the HAlpha line. I am still trying to get the touch on color imaging with multiple layers so pls if yoy have any tips post them. Thx Dirk "Ralph Hertle" wrote in message ... DvandenH: The images are beautiful to see.

Dirk,
a bit more exposure time would be nice, but detail and colour both look very good. Stefan "DvandenH" schrieb im Newsbeitrag bel.net...
