    Re: LHA Aries on a clock
    From: John Pinto

    Not exactly what's being looked for but I keep a clock in my observatory on LMT and as long as I don't need super accuracy I use this shortcut: I look in my Nautical Almanac in the UT column (pretend it is an LMT column) with my clock's LMT and take the value in the Aries column for my LMT hours plus any correction for LMT minutes and seconds and I get my approximate local Sidereal Time (LHA of Aries).  Of course if I need super accuracy I can do the traditional calculation using UT and my longitude.  It's close enough to tell me what's overhead. 

    I also use that LMT with my planisphere for a general idea of what's visible (which is basically doing the same thing as my shortcut method).  Here's a great site where you can make your own planisphere that has both altitude and azimuth lines (similar to the Star Finder) for your latitude:
