[AZ-Observing] Re: Need Advice on Losmandy Polar Alignment

Polar Scopes are not really good enough for Astro-Photography. You are  
almost always are going to have to drift align to achieve better accuracy. If  
you had an Astro-Physics goto mount I could show you Rolands favorite method 
for  accurate polar alignment that is ten times more accurate than any 
polar scope  made. I use that method now on my 1200 goto and it really works!

It was OK for observing but not for photography. Later  editions
corrected the mistake.That is a possible reason that comes to  mind.
