Description
This is the "first light" image with the STL 11000M. Admittedly, M51 and NGC 5195 are not nicely centered, due to my choosing the brightest guide star in the region for my first attempt at self-guiding. The image is still interesting showing the wide field image with colorful field stars and there are at least 40 faint background galaxies visible. The latter include the small blue face-on barred spiral IC 4278 above the bridge and the edge-on spiral IC 4277 above the large, diffuse "E" formed by the tidal spray of stars from NGC 5195.
