An indistinct cluster in heavy galactic starfield, an obvious asterism of six stars at the center matches the DSS image, bright, sparse, large at 10' in diameter, otherwise unremarkable (Archinal indicates this is probably an actual cluster and confirms the discovery description matches the modern coordinates)
Harold Corwin
Espin's position coincides almost exactly with the brightest star in his cluster, which he describes as "Jan. 11 [1900] Cl., triangular in shape, stars 9.5-14". I can make out at least two different triangular shapes on the DSS, so I am not quite sure which (if either) Espin meant. See also IC 2156 which may be a part of this.― IC Notes by Harold Corwin
