Description:
Finding this galaxy was a starhopping adventure. At this time, Bootes
was nearly over the county hospital, and the limiting magnitude was
about 4.7. I had to use a low-power eyepiece to find it. I started at
Eta, which was just visible through my Telrad. From there, I jumped to
70 Vir, and then 71 Vir. From there, I hopped sideways to the double
star Burnham 612, and then finally over to my target.

This galaxy was just barely detectable from my backyard. In fact, I
missed seeing it the first time I tried to locate it. The spiral
galaxy was fairly large and elongated. With direct vision, it almost
disappeared completely. Using averted vision, a nearly stellar core
was visible. The best view was at 88x, but no spiral structure was
visible.
