NGC 55.

Big one here

A strongly overlapping three-panel mosaic, because it almost overflows our field, and we so much wanted that bright blue-yellow pair of stars at the bottom left.

We're rather thrilled to see the effect of the long exposure on the morphology of all the tiny little distant galaxies in the background.

Lum 28 hrs, RGB 4 hrs per channel, all in 30 min unbinned subs. Total exposure 40 hours. Aspen CG16M on 20 inch PlaneWave. New moon.
0.55 sec arc/pixel, North up.

No personnel were frozen during acquisition.

Very best,
Mike and Trish
