Hi Mohammed,
Thanks for the post and I hope you have been keeping well.
From the report of the message you received, I can deduce that you
were not performing a two-star alignment using MODE ALIGN or
MODE ALIGN STAR at the time.
Instead you would have received the message during a TPAS sampling
run.
You would have been in either the MODE CATALOG, MODE IDENTIFY
or MODE TOUR menus.
The display would have been showing "RIGEL KENT" in the top line
and GUIDE with the guide direction arrows in the bottom line.
You then have pressed ENTER.
The display would have prompted "SAMPLE MNT ERR?". You then
would have pressed ENTER. The display then said "TOO NEAR HORIZON".
If you had intended to perform an alignment rather than a TPAS sample,
you should use the MODE ALIGN or MODE ALIGN STAR functionality.
If you never intend to take TPAS samples, dial up MODE SETUP,
SETUP MNT ERRORS, ACQUIRE DATA -> OFF.
If you had intended to perform some TPAS sampling - and that in
itself can be a good thing to do - then I can further deduce that
your location in SETUP LOCATION has in all probability not been
correctly set. In particular your latitude will likely be too far
north of your actual location. If I were a betting man I would guess
that it is still at the factory default setting of NOWEHERE, ATLANTIC
which is at 0 degrees latitude and 0 degrees longitude.
When performing TPAS sampling, Argo Navis uses your location
setting to determine the distance the object is from the horizon.
If it is below the horizon and you attempt to sample it, Argo Navis
will warn BELOW HORIZON. If it is less than 10 degrees above the
horizon, Argo Navis will warn TOO NEAR HORIZON.
Argo Navis, by design, will not provide horizon warnings when you
perform a MODE ALIGN or MODE ALIGN STAR operation.
I recommend you check your SETUP LOCATION setting and whilst you
are at it, also check your SETUP DATE/TIME setting. Once you have
correctly established these, we also recommend you switch SETUP
REFRACTION to ON.
If you require further assistance, please don't hesitate to email.
