Re: APPM Dec Arc Model and NINA "do not sync" option


Yes I think that is correct

I hadn't considered that dec arc modeling approach does not correct for all sky pointing, good observation

As far as I know, doing a sync (recal) does not affect the model. I do recals all the time and it has never affected the model. But Ray Gralack would be the ultimate authority.

Subject: [ap-gto] APPM Dec Arc Model and NINA "do not sync" option

I have two question /consideration that I'd like to be validated.

In my former Paramount ME mount a sync issued by a sequencing software like NINA would result in a model corruption.

I assume with my present Mach 2 the situation is different because:
-if using a dec arc model (my case), pointing corrections are not activated
-every sync should be treated as a recalibration, therefore the model is not affected.

So, I'd configure NINA to send sync commands to the mount.

I'd be grateful if someone can confirm.
Thanks a lot
