Dwarf Spiral Galaxy UGCA 106

This small (1.7 arc minutes), dim galaxy is an elusive target. I believe this is the is the first time it has been imaged and published by an amateur.

On the other hand, with its bizarre morphology, UGCA 106 is a fascinating object. As stated in the Catalog of Southern Peculiar Galaxies and Associations, by Halton Arp and Barry Madore, “the outstanding problem in dwarf galaxies seems to be to explain why the grand spiral design becomes more and more disorganized and irregular as the dwarfs become lower in surface brightness, lower in luminosity, and presumably lower in mass.”

UGCA 106 is included in the Catalog as a peculiar galaxy, meeting the requirements of Category 20.

That is spectacular work! :shock:
Processed as if it is just any other galaxy - this thing is difficult to acquire and extract detail out of!
