Just another weird 'Thunkin' thought ;)
When firing up my/the/your Neq6p or other mount, as most know with most mounts, I presume, it ask's for your time zone, which here Goldcoast/Eastern Aus in +10 hrs, Ok !
So, prior in the 'start-up' procedure, we inject the Lat/Long data, & go to lengths to have these values rather accurate, ie, GPS locations can be accurate to within 10mtrs for argument sake, ok, then We inject the Date & Time to the Minute, right !
Well, Iv'e always thunk - How accurate 'Eastern Aus' is the input of entering the +10hr - when realistically as the Earth rotates, through the timezones, the +10hrs at that instant of time is actually some several hundred kilometers off the east coast, here in SE QLD for this example !
So, theoretically, and roughly, going by the attached image, would it be not wise to say, I would need to wait some 15-20 or so minutes for that +10hr timeline to be, say, overhead or on the Gold Coast ? ?
Hence, when entering the time into the mount - would it be advantageous to take off 15-20 minutes, or for better understanding, set the time 15-20 minutes prior to actual current time of start-up in an attempt to better set the mounts parameters :question:
Therefore, may find the initial 1st star alignment and subsequent star alignments more accurately and in turn, the mount be more accurate ??
Further discussion and/or input could be interesting :question:
