Go to the Storage Setting window, locate and select the image (in Image Management) that you had earlier taken.
If the FITS file that you need is no longer there, or even if you want to use an image from someone else, just make a copy of that FITS file in USB storage from a computer . Yeah, if the FOV is suitable, you can use an image taken with a different camera; even Hubble. A convenient place to copy is into the Preview folder.
Bear in mind that you cannot copy a file to the ASIAIR through the networked Samba server, since you only have Read Access (logged in as Guest) to the Samba volume. You need to unmount a USB drive from ASIAIR, physically move it to your computer, make a copy of the file, unmount the USB drive from your computer, and physically move it back to the ASIAIR.
Once you select a FITS image in Image Management, tap on GoTo to plate solve. This could take a while, since ASIAIR does not know the plate scale of that image (it is like doing a plate solve with focal length set to zero).
If it succeeds with plate solving, confirm that you wish to slew the mount.
The RA and declination will also be placed in the GOTO panel (the one with the North-South-East-West slew arrows and slew rate slider).
At any time (not just when retrieving an image), you can tap on Target in the GOTO Panel, then tap on the + button to save the coordinates (Use Current Position of Mount) for future use. Give it some recognizable name like "My Rigel."
Note that the camera angle will be whatever the current camera angle is set to. Only the center of the image will be retained.
