While you're here, how about checking out the
Astronomy Book
List ? |
Adi,
Try decreasing your slew speed to 3-5 degrees/sec and see if that helps. I
found it to help quite a bit. It defaults to 8 so make sure you change it
BEFORE you do your 2 star alignment. Also you may want to check the alignment
of the OTA with the fork mount. Look in the archives for info on how to do
that. I found that by tweaking the OTA alignment I reduced my goto error from
1-2 degrees to 30 arc-min and then by reducing the slew speed to 4 that I
further reduced the error to around 5-10 arc-min.
