Observing Notes

Andrew Cooper

20cm f/10 SCT

Pretty, round with brighter core, averted vision shows some structure, a few patches are brighter

Charles Messier
13 Apr 1781

Nebula without star, of a very rare light, nevertheless a little clearer than the preceding [M98], situated on the northern wing of the Virgin, & near the same star, no. 6, of the hair of Berenice. The nebula is between two stars of seventh & of eighth magnitude. M. Méchain saw it on March 15, 1781."
