NINA Dither timeout

[Jim Pollard]

I sat down and put some work into this and got my settle time down to around 8-10 seconds from 45 seconds.

I'm guiding with an asi120mm mini and imaging with an asi533 running through a RASA 8 @ 400mm.

The image scale is around 1.6 pixels between the two.

Reading the documentation in NINA, it says a dither around 10 pixels is usually good, and it seems to work for me.

If I dither at 7 pixels in NINA, my imaging camera is actually moving just over 11 pixels.

I changed my dither movement to 7, my settle pixel tolerance to 1.5px, settle timeout to 30 sec, guiding start timeout to 60 sec, and minimum settle time to 5 sec.

Seems like a lot of these problems would be a non issue if there was a little more documentation, even maybe an example, in the NINA manual.

I don't think I'm the only one that was having problems.

Hopefully this helps someone out.

There are examples an explanations in the NINA documentation that you presumably read:

https://nighttime-imaging.eu/docs/master/site/advanced/dithering/

If you have any uncertainty about specific aspects of this, then I think those are questions that are better posed on NINA discord, not to the PHD2 forums

It might be that your configured image scale isn't accurate, or other things related to that.

Dale,

All I'm trying to do is let people know that I have NINA working with PHD2 without any problems.

Maybe I didn't write well enough to get that point across, maybe you misread my intent.

I'm on your side here. NINA works great with PHD2.

I thought this was the correct place to post since there have been so many people talking about this subject in the past.

I just wanted to start a topic so people could find the information when doing a search.

You are correct about the documentation. That is where I found the info to set dithering parameters correctly.

Sorry for any misunderstanding.

Jim
