NGC 7217  - galaxy in Pegasus

NGC 7217 



Wikipedia says that NGC 7217 is a gas-poor system whose main features are the presence of several rings of stars concentric to its nucleus: three main ones the outermost one being of the most prominent and the one that features most of the gas and star formation of this galaxy plus several others inside the innermost one discovered with the help of the Hubble Space Telescope; a feature that suggests NGC 7217's central regions have suffered several starbursts.There is also a very large and massive spheroid that extends beyond its disk.

It was my more or less randomly choiced (but well placed) galaxy in order to use the time before my main object would be well visible from my yard. With not so much data the result is perhaps not too bad.
