Re: Gemini 2: Polar alignment


 

Rahul,

The difficulty I find is with "daylight savings time" and the 1 hour uncertainty it creates.? It is far preferred to set the UTC time, and then your longitude and latitude work properly.??

On the Gemini-1 you set the UTC time directly.? The special entry code format is given below.

But in the Gemini-2 you enter local time, with your hour offset to UTC.? I can see how this could be a cause of trouble.? There is an easy solution.? A nice member of our group explained recently that on the Gemini-2, you enter the UTC time this way:
Set the Time Offset hour = 0.??
Enter the UTC time as the "local" time.

Your 1 hour error ought to be fixed by entering only the UTC time.?
Try it and?let us know if that?works.

Best,
Michael

------

Gemini1 time and date UTC format, from the Gemini1 manual.?

UTC Date/Time
The "UTC Date/Time" menu item is where you set Gemini's real time clock (RTC).
Upon executing "UTC Date/Time" the UTC date and time display freezes but the RTC continues to keep time.
The display of date and time from left to right reads as follows:?

"yymm.dd hh:mm:ss"
(yy = year, mm = month, dd = day, hh = hour, mm = minutes, ss = seconds).

So would be for 2021, Feb 23, at 06:15:25 am you'd enter. You take the 21 is the last 2 digits from 2021, the 02 is February, ...:

2002.06 06:15:25

For time after noon like 14:00 = 2pm enter like
2002.06 14:15:25

Thank you Michael.

For a moment, if I take imaging out of the equation.? I don't understand even after polar aligning the mount , mount in CWD postion why two star alignment won't work 100%? I want to fix this first before I jump to other tools/methods and imaging.

One thing I noticed tonight is that even when I query GPS hand controller was showing time 1 hour ahead of actual time. I was under the impression G2 using GPS figures out the local time as well. Do I need to set time manually?
