If you created this file, please note that the fact that it has been proposed for deletion does not necessarily mean that we do not value your kind contribution. It simply means that one person believes that there is some specific problem with it, such as a copyright issue.

I had a look at File:NGC253.jpg (following the new article he:NGC 253) and couldn't help noticing that this is a professional image. A short search found its source to be here. It seems to me that this image, as well as other images from the same source that were uploaded by this user, are copyrighted. It's possible that the user is authorized by the observatory to waive the copyright and upload those images to Wikimedia, but still, a credit and a link to the source must be given.
