My 6" AP155 f:7 is best suited to wide field objects, one could not in any since of the word consider M51 as being a wide field object. I cropped apx 80% of the image to display M51 at 100% resolution. Of the possible 4,007 pixel columns of the STL11K M51 only covers 305 which makes bringing out finer details quite difficult. The link above takes you to a larger field of view, this one about 1/3rd cropped, to display several near by Gx's to the right of M51. |
