Due to popularity, I thought it would be a good idea to update the AstroTortilla tutorial. The settings recommendations have been altered slightly, to be less accurate to your actual field of view. For example, entering 0.525 and 0.655 degrees into Scale minimum and Scale maximum may be pretty exact, but I have found it better to just enter 0.5 and 0.7 degrees (in terms of plate solving successes). The screenshots have been updated accordingly.
Moreover, a new section 5 has been written, titled "Things to Try when Plate Solving Fails to Centre the Target or Fails Completely". A bit of a long title but to-the-point. The inspiration has been the various reports from people that despite my tutorial, they still suffer from the dreaded "Field 1 did not solve" or "Re-centering" getting stuck problems. There are number of suggestions in this new section, including downloading the 4100 series of astrometric index files as a last resort (which are more suitable for wide-field setups).
If you are having any problems with AstroTortilla, or have in the past, it may be worth reading this new section. Enjoy!
