I have done the same thing Eric, and it was in front of a group of BAS members during a busy public viewing night at Mt Coot-tha Lookout. I spent well over an hour trying to re-align the scope before I realised that I changed the day but did not update the month
. At least I was still able to move it onto a target manually.
Still waiting for some clear skies to track down the 'pup'. This weekend is looking promising.
