With simple maintenance with the PEC and dec adjustments a good
autoguider will do its job most of the time. The AP, Paramount, Losmandy
and others still use a auto guider to get excellent shots and if you add
the SBIG AO system, even better. All of this must work to get excellent
guided pictures and much less with imaging. With software and imaging I
can take several images and piece them together with cropping to get very
good pic's. The LX-200 makes an excellent image camera (lens) with
plenty of bells and whisles to make imaging really fun. I am pretty much
bored with taking long exposures on film. In a few minutes I can capture
a image in the best part of the sky and I can do this all night long.
Pretty amazing and fun.
