A Battlestar in Cetus

Three lovely mild dry nights at Terroux allowed me to collect the data for this image and when the moon disappeared each night I had a great time visually inspecting many other galaxies in the area with the new visual scope - bliss

The Image:

Looking like a huge Colonial Galactica class Battlestar being chased by a small pack of Cylon Raider craft, NGC 247 in Cetus is actually a nearby dwarf spiral galaxy seen tilted somewhat edge on at a distance of about 11 Million light years away. This is the same distance as to the more famous nearby spiral NGC 253 but NGC 247 is only about 2/3 its size. At this relatively close distance many young star clusters with massive blue stars are clearly resolved and many pink HII regions of star birth can be seen scattered throughout the galactic disc.

Two of the much more distant line of small 15th+ magnitude galaxies, at the top right of the image, seem to be connected by a faint bridge of material, most likely stars.

EDIT: At the published 11 Million Light Years distance, the large reversed C shaped HII region at the bottom of the disc there I calculate as being approx 2400 Light years in size - that's one biiiiig nebula
