The galaxy precedes a pair of mag. 9 stars by about half the eyepiece field, so by about 10’.  The star lower left in the drawing required AV. NGC 2798 was seen as an oval core oriented NS embedded in a tight round halo. The companion NGC 2799 was not seen with any confidence despite checking its exact position on charts after initial failure. The evening sky is turning milky, the Coma and M44 Beehive star clusters are barely visible now.
