I used an Orion Star Shoot Pro V2 ( APSC 6MP OSC sensor) camera and 31 x 900sec subs for a total integration...

Maybe this is more what you wanted.

Guider.FullFrameAutoguide
pause (10) ' (this is where you would insert image sequence)
Guider.StopAutoguide
Camera.Start (1)
Camera.Wait
Camera.Autofocus
Guider.FullFrameAutoguide

Thanks, I'll give that a try.

Is it possible to write a script that calls single star auto-focus and multi-star autoguiding?

It seems that these two methods can't be used together.

Jep, and as I wrote : There are a normalization sigma clipping i dont think thats the same, as in PI, DSS or Siril ? sigma-clipping.png Sigma Manual.png And it's listed as a new features in AA8 https://www.msb-astroart.com/example5.htm I read through the Siril documentation and it seems that AA8 im...

Thank's Dunmunro
I already have & use AA8. But i don't find sigma clipping.
Only sigma and sigma + sum

See:
Tools->Preprocessing->Options

That's fully implemented in AA8 - check out the AA8 demo.

They are present throughout the whole frame. Thinking that they might be Hot Pixels, I applied the hot pixel filter to each one of the 20 x 5mins subs before dark frame subtraction, aligning and stacking (Sum). I Suspect that they are hot pixels, which have been elongated during guiding, and thus b...

Thanks dunmonro for the quick reply. Yes I have the astroar8.DAT in the AA8 directory. I save and load my platesolving parameters as you described and both the platesolve or immediate platesolve work well. However, the platesolve in the telescope control (center platesolve) never works for me in AA...

@dunmunro, thanks for the comprehensive summary on the plate solving centering function in the "telescope" function. I searched for the "platesolv.dat" file you mention in the program folders of Astorart, but couldn't locate it. I was using it happily in AA7 with 80-95% success rate. In AA8 however...

Which two cameras?

Hi, the "AA6 method" cannot be used on multiple stars at a time, but there is no need for it: the method "Small disc" is actually the same thing, even more precise. I suggest to compare in the focus window the "AA6 method" and "Small disc", they are very similar. Fabio. Thanks, I'll compare them to...

Feature request: AA6 focus algorithm with FF focus.

Would this be possible? I find the AA6 focus algorithm the most accurate, but it's not available for FF AutoFocus.

thanks
