Fullframe Autofocus with elongated stars
Fullframe Autofocus with elongated stars
Hello.
When i use the full frame autofocus, the images acquirted show elongated stars along the process.
Anyway, the final focus seems to be correct. Is this normal? I guess not!
Thanks.

That never happens when I focus. Do you have guiding active when you focus? If yes pause the guider and see if that helps.

Hello.
No. Guiding is not active.
Besides, if i get a single image just before or after focus, the image is perfectly normal with round stars!

My mount sits in an equatorial wedge very well aligned.
Even if i do not use guiding, any shot shows round stars even with long expositions.
Just before focus i usually acquire a simple image a few seconds long that looks fine.
Besides, the Full Frame autofocus uses 4 seconds shots.
Also, the camera is well aligned to the north but those elongated stars are slanted.

Re: Fullframe Autofocus with elongated stars
Have you checked all the connections between the camera and scope especially the focuser ? Maybe just a lose connection that flexes during auto focus.
Good luck
