NGC 247, 38 hours of light

This image is combination of LRGB and Ha light frames totaling 38 hours of exposures.
Unfortunately the frame is quite tight because I had only one guide star to go with.

There is a odd almost starless area at the right side of the galaxy where no Ha-areas are visible nor will there born any new stars. This is some kind of mystery why it exist and how has it formed.

Image taken with Harlingten Atacama Observatory’s 20″ Planewave CDK telescope and Apogee Alta U42 CCD using LRGB and Ha filters.
