28cm f/10 SCT, NexStar 11" GyPSy @ 127x

Big, bright, an edge-on galaxy elongated east-west, a stellar core sits on the north side of an obvious dust lane bisecting the disk from east to west

46cm f/4.5 Newtonian, Deep Violet @ 175x

A beautiful edge-on spiral, a distinct dust lane bisects the disk with a nearly stellar nucleus to the north side of the dust lane, 6'x3' in size running east-west, bright, easy to find north of Corvus

Pierre Méchain
May 6, 1783    

On May 11, 1781, I discovered a nebula above Corvus which did not appear to contain a single star. It emits a weak light and is difficult to find if the micrometer wires are illuminated. This does not appear in the Connaissance des Temps."
