Argo Navis AUTO ADJUST ON feature

Suffice it to say I found 4 times as many objects in that time than I usually find. A great gadget, and familiarity will only make it better.
Hi Paul,

Thanks for the post and you were indeed lucky to get a brief observing run
given the interminable cloud of late.

Now that you have determined the encoder direction senses, we recommend
you begin to use a feature called AUTO ADJUST ON if you are not
doing so already. Please see this post on how to set it up and use it -

The AUTO ADJUST ON feature can help refine the Alt encoder reference point
and thus very often improves the pointing performance.

Beyond that, Argo Navis has the in-built Telescope Pointing Analysis System - TPAS
which can help analyse and potentially compensate for certain systematic errors
within the mount. However, before reaching for the "heavy guns" that TPAS provides,
using AUTO ADJUST ON when you perform the FIX ALT REF step is what we always
recommend at the point you are now.

Pages 57-60 of Edition 10 of the Argo Navis User's Manual has more detail about AUTO
ADJUST ON in the section on FIX ALT REF.

If you should ever need any help, please do not hesitate to drop me a line
or to give me a call. Thanks again for the post and great to hear you are finding
more stuff than in the past.

Best Regards
