+<h3>Plate Solving</h3>
+<p>This module can plate solve images and update FITS header with solution for FITS and XISF images.
+<b>Profile</b> this set various parameters that affect star extraction and solving.
+<b>Starting point</b> program will try to automatically determine optimal starting point which helps to speed up solving.
+You can leave one or both unchecked then it will attempt to do blind solving. If the position or scale is wrong it can actually
+fail to solve.
+<b>Solution</b> this section contain resulting solution like RA,DEC coordinates center of image, image field of view, orientation as degrees E of N,
+image scale in arcseconds per pixel, number of stars extracted and HFR fitting and eccentricity. Then there is log window for debug information from
+solver.
+</p>
+<p>Then finally there are various action button. Settings button show dialog where you can set path to existing index files or auto download some.
+Extract button will just extract stars from image and it will show their count, HFR and eccentricity. This action doesn't need index files.
+Solve button will try to find coordinates of images. Abort button will stop extraction or solving. Update FITS header will update FITS fits keywords
+with found solution.
+
+<p>In settings dialog you can set path to index files which is by default custom internal one. It also try to locate commonly used path from other
+programs like KStars for astrometry.net index files.
