Hi,

I have no time right now but have experienced with this type of
alignment during the past weeks. It can be done in more than one way.
The CCD version of the drift method works but is not the best way! Let
me first digest another 1000 e-postings and give attention to some
urgent taks.

I'll come back on this later...
In the mean time I suggest that, if interested, you get hold of a
detailed image (DSS) of 30x30 arcmin..of the 2000 polar region centered
on actual North (or South, as in my case).

Happy 2002 and safe and clear dark nights for all !

Maarten,

You basically just you the autoguide feature to track
declination drift. Of course, you need to turn off guiding
corrections in declination but leave RA corrections on. I
use CCDOPS on my SBIG camera and autoguide with only RA
corrections. It shows what the current declination drift
is but also allows you to log the error into a text file
that allows easy importation into Excel so I can create
drift graphs. This is much more accurate than just
eyeballing the drift in an eyepiece.
