Description

Trying a rarely imaged 2' x 2' galaxy (about the size of the Ring Nebula) with my planetary setup. Hubble tried this too...

NGC 278 with Hubble Wide Field Planetary Camera 2

Here, 60s luminance subs are between 1.24" and 2.1" FWHM. 300s RGB subs are between 1.6" and 2.8".

"NGC 278 lies some 38 million light-years away in the northern constellation of Cassiopeia.

While NGC 278 may look serene, it is anything but. The galaxy is currently undergoing an immense burst of star formation. This flurry of activity is shown by the unmistakable blue-hued knots speckling the galaxy’s spiral arms, each of which marks a clump of hot newborn stars.

However, NGC 278’s star formation is somewhat unusual; it does not extend to the galaxy’s outer edges, but is only taking place within an inner ring some 6500 light-years across. This two tiered structure is visible in this image — while the galaxy’s centre is bright, its extremities are much darker. This odd configuration is thought to have been caused by a merger with a smaller, gas-rich galaxy — while the turbulent event ignited the centre of NGC 278, the dusty remains of the small snack then dispersed into the galaxy’s outer regions. Whatever the cause, such a ring of star formation, called a nuclear ring, is extremely unusual in galaxies without a bar at their centre, making NGC 278 a very intriguing sight."
