Quote:I have had this mount for about two years and it has worked just fine. Last night I set it up -- leveled the tripod after polar aligning etc.--- then went through the alignment process and it worked ok but was a little off on going to Procyon. I then rebooted and went through the process again and instead of coming up with Capella as the first alignment star it came up with Sirius. When it went to Sirius it went in the correct direction to the south east but it tried to aim the scope below the horizon. I then started all over double checking my GPS coordinates, time, date, etc. and the same thing happened. I then replaced my power supply and the exact same thing happened. Help....what is the problem and what is the fix?Thanks in advance!~jerry

Quote:Jerry, When it happens again...and it will... Loosen the clutches (Probably RA only) and point the scope at the target star. Then continue with your alignment. Try it and see what happens.Stan
Quote:I have had this problem with both my CG-5 and my CGEM mounts. I have addressed the problems of power and cabling. This has fixed other problems effecting my mounts, but the one described by Jerry, that of the scope pointing in a downward position has continued to happen to both of my mounts. I took the advise given here on CN of doing a factory reset when this happened. This involves a considerable amount of time and it did not always solve the problem. I have found that when this pointing downward problem happens to me, I simply loosen the clutch and move the mount in RA to align the target star and all is as it should be from there on. I then continue with my alignments without any further problems. I no longer waste my time on factory resets. I have nothing more to add other than that on my mounts and in my experience this has worked for me. Stan

Quote:The error I'm experiencing is approximately 70° misalignment in RA. I hardly think such a large error can be caused by incorrect data input like the wrong time zone. The data input has been through both manual input and CN16 GPS input. Both have been checked and reentered numerous times and also by data base input means. I am fairly familiar with the sky and I know that Rigel is not 40° below the horizon on the 5th of March at 2100hrs on the west coast of America.

Quote:So when I enter the time zone as Pacific and as the GPS also enters the time zone as Pacific the mount thinks it's 5 time zones away? What do you think the fix is for that?
Quote:Rod,I have seen this problem posted here and on other forums. Jerry describes this problem in his OP. It would seem odd to me that of all of Celestrons mounts I have the only 2 that have the phenomenon pointing to the ground when they should be pointing to the sky. There are more things in heaven and earth, Horatio... Stan
