Re: Meridian Flips and NINA


 

Jim, hope you are in a nice cool place today!? ?

Here is result from last night. So far, still consistent with my understanding of the NINA settings:

I was imaging M20 which transited meridian at?01:51 CDT. These were the 300s exposure windows prior to the flip:?
?
(a) 01:39 to 01:44 WEST
(b) 01:44 to 01:49 WEST
(c) 01:49 to 01:54 WEST

Exposure (c) was allowed to start and complete from the WEST side because:
- "Pause before Meridian" = OFF
- "Max minutes after the meridian"?= 45min, so the NINA safety limit at 02:36 CDT was past the exposure's expected end time
- "Minutes after the meridian" = 2min, so earliest flip time of 01:53 CDT had not been reached.

Once (c) completed at 01:54 CDT,? we were past the earliest flip time so?NINA flipped before starting exposure (d)
?
(d) 01:59 to 02:04 EAST
(e) 02:04 to 02:09 EAST
(f) 02:09 to 02:14 EAST
