Cluster and nebulosity complex involving NGC 1973-1975-1977-1981.
Nebulosity was not positively seen but the clusters were a nice sight by
themselves. Very large and sparse cluster involving bright stars. Three
particularly bright stars are found towards the direction of M42 around which
nebulosity was sometimes suspected but this could also have been scattered
starlight as I have seen often in M45
