Spiral versus Ellipse in Virgo

Quite a contrast. The beautiful grand design half-face-on spiral with tightly wound arms at top left is NGC 5364. It has a pin-point core.

The very unusual orange-coloured elliptical at top right is NGC 5363. Close inspection shows fine branching dust-lanes, suggesting it has been munching on a spiral not so long ago. It seems to have three nuclei.

The thumbnail is a crop. The full image is 30 min arc across, 0.55 sec arc/pixel, showing another beautiful yellow near-edge-on spiral at bottom right, and at least 50 other galaxies in the far distance.

L 7.5 hrs, RGB 1.5 hrs each, all in 30 min subs. Aspen CG16M on 20" PlaneWave on MI-750 fork.

Acquisition and processing with our own Selene and GoodLook 64.
