   To prepare your images for display, you need to plate-solve the images (one time only). To do this, find an image in the table, click on its filename, and then click <guilabel>Solve</guilabel> below the table. The Solve button's label should switch to <guilabel>Cancel</guilabel> during the solve, and then when completed successfully, the solved parameters are displayed in the table and the status is changed to "OK".  A successful plate-solve's information is stored in the user database so that solving doesn't need to be repeated. The solved image should from then on appear in its proper position in the SkyMap. You can plate-solve multiple images in a single operation by clicking on the first image's filename, then shift clicking on another filename. All the image files between the filenames should be selected. Then clicking Solve will attempt to solve them all. However, KStars will not attempt to plate-solve images whose status is "OK", it will skip those images. (If you wish to re-plate-solve images with status "OK", then manually change their status to "Unprocessed" and click "Solve").  It is possible that if you select several images, a few of them will not be successfully solved.

-Plate solving these images can sometimes be difficult. That is because at this point the system has no information as to the scale or position to look, and thus it is a blind solve. To improve your chance for success, you can enter an approxiate RA/DEC center sky position into the RA and DEC columns for the row you are trying to solve. You can also add an image scale, in arcseconds-per-pixel. You can add a default scale to the right of the Solve button in the box labelled <guilabel>Default a-s/px</guilabel> so that all solving attempts use this scale by default. You can also add a scale directly into the table-row-column, which would override the default. You can choose which StellarSolver profile the solver uses (these profiles can be edited in Ekos' align tab). Finally, you can adjust the solver's <guilabel>Timeout</guilabel> in seconds.

 If you have problematic images that won't solve, you can still display them by manually entering the values (that the solver didn't find) into the table. They are the RA, DEC, arcsecond-per-pixel, orientation angle, and east-to-the-right (or West-to-the-right) settings. Once you have done that, you can then change the status to "OK" and KStars will save these values to the user database as if they had been automatically solved.
