NGC7331 in Ha Spiral Galaxy NGC3771 in Andromeda. I've seen some spectacular images if this galaxy but this disappointed me. Of the 15 x 300s subs taken only three had round stars and a further 3 were removed due to the star trails being 4-5 star diameters long. The remaining nine images were 'salvaged' using Lucy-Richardson and then SD-Median combined with the rest. There is some tantalising glimpse of the detail ... will do better next time...
