Description:
At 71x it appears with direct vision in the FoV as an extremely faint galaxy. I tried to make the view better by increasing the magnification to 250x to make the bright sky background fainter, but it just made the object disappear completely. I went back to 167x, that gives me the best views. It is so faint that I need to use averted vision all the time. Highly elongated to the NE-SW. It must be a really interesting object on a darker, less foggy sky.
