Corwin's Notes

===== NGC 6846. The RNGC position is 2 degrees too far south. At the correct position is a compact little cluster matching Stephan's description exactly: the three brightest stars are clear enough that he could see them, but the others are considerably fainter, so the entire group must have looked quite nebulous to him.

Steve's Notes

===== NGC 6846 17.5" (9/7/91): at 225x appears as a small, faint clump of stars over unresolved haze. Elongated about 3:2 E-W with dimensions 1.5'x1.0'. A mag 13.5 star is off the NW edge, a mag 14 star is at the west edge and three additional mag 14 stars in a clump are just visible over of the haze although clean resolution is difficult. K 4-41, an extremely faint stellar planetary is situated just 2' NE! It wasn't visible without a filter, even using the ESO-Strausberg finder chart. But adding an OIII filter iI was able to glimpse it several times about 15" S of a mag 14 star. Appears stellar and estimate V = 16.0-16.5.
