Observing Notes

Andrew Cooper
29 May 2017 Hale Pohaku, HI (map)
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

17 Apr 2010 Hale Pohaku, HI (map)
46cm f/4.5 Newtonian, Deep Violet @ 175x

Beautiful, a wonderful edge-on spiral, large, bright, a bold dust lane cuts across the disk, bright core to the north of the dust lane

28cm f/10 SCT Nexstar 11

Very nice!! Sombrero! bright! good dust lane and a condensed core, elongated 6:1 east-west

Andrew Cooper
18 Apr 1999 Organ Pipe National Monument, AZ (map)
20cm f/10 SCT

Finally a more interesting fuzzy! dust lane clearly visible in the elongated direction, elongation on the PA 90 degrees

6 May 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."
