NGC 247 and many tiny friends

NGC 247, near Diphda, is a spiral that looks like something went right through it and made an 'ole.

Back in 2014 we photographed the main galaxy.

We've now reframed to include the little chain of 5 or 6 distant galaxies off to the right. We've thereby added more luminance and more colour. Grand total 13 hrs of luminance and about 3 hours per channel of colour.

We've processed the image to bring out more of the teensy tiny galaxies far, far away, which now show their form far better than before. (There are at least 58 of them).

The thumbnail is a crop. The full frame is here.

16803 chip in various camera bodies. 20 inch PlaneWave CDK. North is on the right. Full frame is 0.55 sec arc/pixel.
