I've got a major issue with my scope. I owne it since 2002 and had inital problems (I had to send the scope back due to a clutch problem). Since then it worked all right. In April the hand controller (HC) started to die on me (it reset after an alignment). I sent an email to Celestron Tech support and they told me I needed a new HC. After almost 2 months I finally got it (I had to send the old one back), plugged it in the scope and then I could not align the scope. It would not get correct GPS data. I exchanged the battery in the GPS receiver and GPS is working fine now. Celestron is very slow in responding to emails and sometimes they don't return phone calls; maybe they are really overloaded. They claim that my email (from work; I work for an automotive company) gets filtered by their spam filter...
I updated the HC to NXS 4.10 and the motors to 4006.
Anyway, they really have not been able to help me yet and I am getting pretty pessimistic. Here is what HW I have:
- The GPS unit is a NXW249 Rev B. It is mounted in the inside of the left fork arm.
- The GPS/Motor board shows 4.05 for GPS, I did not find another revision on the board. The board is mounted in the right fork arm close to the base.
- The base board (the one that connects to the slip ring) is a NXW193 Rev C dated 2001.
My misaligment manifested istself as follows: I performed a solar system alignment with Jupiter and then asked the scope to go to Arcturus. This worked roughly, Arkturus was in the finder scope. I had to move roughly half the diameter of the finder scope to get the star in the eyepiece though. I tried Vega next, same thing. 18h 37.160 min and 38 Deg 47.262 (or 18h 37min 36sec and 38 Deg 47’ 15 sec) was the position it should have been and the scope showed it at 18h 42min 45.9s and 39 Deg 46’ 47’’.
I tried it with a single star alignment with basically the same results. I can't do two star alignments since the stars are so far off position that the scope does not accept the correct position.
I did make sure that my viewing location is correct and that the right time zone and DST are set.
It looks to me as if the sherical coordinate system is off.
Any ideas ayone?
