NGC 2903

Here is my look at NGC 2903.

I have again persisted with my manual HDR approach to realise as much detail and colour variance as possible. I also experimented with various levels of deconvolution, while applying too much creates 'white-worm' type artefacts it does provide more sharpening to the darker details. So I took a few versions and layered in the sharper dark detail (being careful to eliminate any bright areas and star dark halos) back onto the standard decon version.

 

Despite being one fo the brightest galaxies in the northern hemisphere it was excluded from the Messier catalogue. There is a nice write up here www.universetoday.com/35296/i-coulda-been-a-contender-ngc... by the late Tammy Plotner that provides some interesting insight into this galaxy.

 

Enjoy.....
