Processing Images – NGC 891 (Part 1 of 3)

NGC 891 is an interesting spiral galaxy in that when we look at it we are looking at it edge-on so we don’t see it’s spiral face. This is a galaxy which is of great interest as it is thought to resemble our very own milky Way galaxy.

We are using 4 exposures to process this galaxy. If you look below you will see the first 3 exposures which are from left to right filtering out the light spectrums of red, blue and green.

You will notice that the red exposure on the left has the most detail so we can assume that the galaxy will be predominantly red in color.
