NGC 5101, 5078, and friends in southern Hydra

The delicate, bluish face-on tightly wound spiral is NGC 5101 in southern Hydra. The edge-on spiral with burnt-orange core threaded with branching dust lanes is NGC 5078. It itself has an evil companion which looks very like the meat-hook galaxy.

There are hundreds of other galaxies near and far in the image, many showing clear spiral structure. There seems to be a very busy cluster of distant orange galaxies about 20% of the way toward 8 o'clock.

Lum: 7hrs in 1hr unbinned subs. RGB: 2.5 hrs each in 30 min unbinned subs.

We are very grateful that some much needed 40 mm of rain is coming to the thirsty central west (there's not so much feed left in many paddocks), but it means that further hours on this one will have to wait till next new moon.

Very best,
Mike and Trish
