Re: Meridian flip sanity check please?

 

Yes, that's right: set the goto limit of 3.45 degrees before the safety limit.

Meridian flip is a function of a German Equatorial mount. Most people would prefer not to do a meridian flip. If you can get away with safety limits at 120 degrees or even more, then you can continue to image much longer on the same side of the meridian, possibly even avoiding a flip. It's a tradeoff between safety and convenience :)

Gemini interprets Goto limit set to zero as the default, meaning 2.5

didn't flip.

AH, I missed that the western GOTO limit is not degrees past CWD..... it
is degrees EAST of western safety limit, right? That would explain it.

So with tracking = 0.25 degree/minute if I want the flip to occur at or
after 5 minutes after meridian with a western safety limit of 95, I set
the western GOTO limit in Gemini to "3:45". Did I get that right?

It is tricky working in minutes of time in NINA and degrees in Gemini ;)
