Elbrus star locator can be used to solve the image you just take with your camera.
Look at the program page for instruction http://www.astrosurf.com/pulgar/elbrus/elbrusin.htm
Before you can use it the Elbrus program must be calibrated for your images. Then select File / E-Wait for message.
Also be sure to set the parameter: “Add the WCS in the FITS header”.
This is a Windows only software but I find it easy to install and use on Linux with Wine.
On the astrometry preference you can set both the DOS and Unix path to the image data to help with this use.
To install Wine on Linux or macOS see Wine web pages.
On Linux the best way is to install the wine packages provided by your distribution.
