Hi Chris
One very big plus with the EM200 for grab and go imaging at multiple dark sky sites, is the superb Polar Alignment Scope. It uses a couple of circular, illuminated reticules to achieve very accurate PA. There is a Month/Day circle (outer) and a 24 Hour circle (inner) which you set to the current Date/Time to position Sigma Octans correctly in the FOV.
Although it is designed for the N hemisphere, I have written an Excel spreadsheet to convert to S hemisphere values and I run this on both my notebook and PDA.
The conversions are simple. Make Months run Anti-Clockwise and make the Hours run Clockwise. See attached diagram for N hemisphere reticules.
Cheers
Dennis
