Andy made a few comments about this galaxy so this is trying to give a better view of it.
I’ve added some more luminance to give a total of 2 hrs 20 mins to the ngc2903 image. A quick process to try to show the full extent of the galactic arms, especially the one coming round the bottom of the galaxy. This is the full image with no clipping so it is 16.8 x 22.5 arcminutes.
Andy, just realised I gave you the FOV but you wanted image scale. Image scale is 0.97 Arcseconds/pixel
