If you observe at another local sidereal times, you may use the 2018, 2017, 2016, 2015, 2014, 2012 maps or (having an alternative for more turbid air) or 2011 maps (even if the planets were elsewhere those years, and brighter or fainter). Maps for 2011 and 2012 are for January-April only. A pleasant feature is, they have a screen-friendly variant of white stars on a grey background. Should I add that kind for 2018 too?
For cases the sky luminance is very high and almost no stars are visible (as during twilight) all-sky maps may be useful, available in subdirectories "A" or in "latitude" subdirectories.Jenik, Hollan at mail.muni.cz
Files like CygSep24.pdf etc. within constell are symbolic links to the generic names like Sep24/Cyg/all.pdf. File all_dates.zip contains all the date-named subdirectories.
Subdirectories within latitudes contain long-name symlinks to files in the date-named directories, a large ??.pdf assembling all small maps and a smaller ??A.pdf with all-sky maps combined. These subdirectories are the best URLs for an observer staying in a given latitude.
All maps have been produced by map_bsct programme, adapted to avoid plotting a large blob at [0,0] when using Hipparcos catalogue. Each set has been produced by its all_*.sh script (or, if more than 1 local time has been computed, by scripts like *_23h.sh etc.) using local templates *.tex file (manually adapted for each chosen central star) with descriptions. No manual editing of the output *.eps files had been made. Listing of the *.eps within subdirectories "single" is suppressed, but they are there, being smaller than pdfs made from them. All *.sh (bash) used are listed.Jan Hollan
