[APML] ST-4 question

[Alan Voetsch <alanv12952@yahoo.com>]

Hey all,

Last night when I calibrated the ST-4, it did not return the star to
where it started. Started at 52 50, ended at 58 50. It passed
calibration and I started an exposure. 50 minutes in it lost the
guidestar.

Tonight, the same thing happened during calibration. Started at 52 48,
and ended at 58 48. I moved it back to 52 and started the exposure. I
will keep closer watch on it tonight.

Also the brightness readings are sorta wacked. Going brom a boost of 2
to a 3, increased the reading from 13 to almost 50. That is much more
than normal for my guider. Usually it would move up to 20 or so.
Tonight again, the brightness reading is lower than I would have
guessed for this star.

It has never not returned the guidestar to it's starting position
before. Anyone have any idea why it might start doing this?

Thanks,
Alan
