Re: Not keeping date up to date; + lunar tracking speed error:

You should AFAIK be setting UTC date/time. Not local. ?

Could this be the problem as they usually differ by a day.. At least in the evening in North America.. ? Derek ? ? You have a Gemini-2.... so I can't say. If this were a Gemini-1, I'd suggest the Epson RTC chip may be defective.? I have bought extras if those chips, though I know of no Gemini-1 actually suffering time-keeping loss. However, I do not know what chip keeps the time in the Gemini-2.? I don't own one yet.? If Losmandy won't replace your unit, and the trouble persists, I'd be willing to take a look at it. ?

Brian, I will check this out tonight when I get home and see if my Gemini still has the correct time. My tracking the New Years eve was as good as my polar alignment. I left the mount to sit for 30 min. And it was just a little off where I left it. I am too new at this to really help though. Clear Skies?

Lo all,
I seem to be having a problem with the Gemini 2 on my Titan keeping the date up to date.? The time is remaining correct, but it lags behind on the date, I have had to go in and update the date every time I go to use it during December.? I know you might be thinking "battery" but it has been replaced as of the first incident, and is showing 3.10 volts in the web interface.? Once I update and set the date the targeting works good, so it seems to just be Gemini is not keeping up on the date.? I have tried both turning the mount fully off as well as leaving it on in the observatory, seems to make no difference.
Also just this last session I began to have a tracking error when going to the Moon, the mount would got to fine then take off @ about 8X "tracking" the Moon.? Yea zip!!!? there went the Moon!? In manually switching the tracking with the HC to SideReal it goes back to tracking at the SideReal rate without an issue...? Kind of weird, I'd think if the tracking was going to be messed up it would be messed up at any of the different rates not just lunar.? I think I will try a factory reset next outing and see if anything changes, but any thoughts in the mean time??!
Thanks & CS!
Mark
