From the right click menu you can draw an overlay with the position and name of the objects in the image.
By default CCDciel use a database of 30'000 objects, if you need more faint objects you can install the Hyperleda database with more than 5 million objects.

Because of it's size this database is not include with the program and you have to install it once.
You can find the installer for your system (.exe, .dmg, .deb or .rpm) here:

https://sourceforge.net/projects/ccdciel/files/hyperleda/

If you do a custom install the file must be in ccdciel/data/dso/
