Hello,

 

Well I have to add another problem with maintaining guidance. We had two small earthquakes tonight at 4.2 and 3.0 centered about 50 miles north of me.

 

Here is a snapshot of my HFR and Star Count from NINA tonight. Can you tell when the earthquakes hit?

 

If its not one thing, its another.

This has me wondering if an ASCOM Safety Monitor driver for the USGS ShakeAlert API would be of any use.

Did NINA do an auto-focus? smile.gif

I'm curious how frequent they are for you to have that size measurable impact?

Just consider it to be natural dithering.

What time were the earthquakes? I was imaging last night in Oakland (about 35mi North on the East side of the Bay) and felt or saw nothing. My subs looked clean all night and in fact it was the best seeing and data I have collected in about the past month. 

 

This was the HFR History starting at about 8:15PM and each sub was 10mins long. I finished with 35 clean usable subs.

To the OP, your graph and story of the events is cooler (to me) than another astrophoto.   Thanks for sharing.

 

I don't know how you AP types don't go insane with all of the things that can go wrong...

Here is a link to the earthquake.

 

So around 8pm. Looks like you set up just after they occurred.
