Notes: Found in a hexagon of stars (four ~13th mag and two much brighter). The galaxies lie behind a right triangle of ~14th mag stars. Proved tricky to identify to start with but once found was actually moderately easy. The spiral arm extending towards UGC 1813 was seen ~ 10% of the time. Otherwise the nebulosity was without structure. UGC 1813 itself at mag 15.1 was not seen, unsurprising in the less than ideal conditions. |
