Hey all,
does anyone know what can be the cause of these double stars? first thought was pinched optics or tilt but this seems like a bit too much for just that.
Thx for the help guys :)
the starmask is a 7/8H stack lightly stretched

Unless it’s on every frame in your data set, it’s tracking errors from your mount. Backlash etc. It basically clunked into place.
Due to the backlash on my mount I get this after almost every time I dither.
I would blink through your frames one by one. To get this kind of effect there would have to be movement, not between subs but in single subs themselves. The stars would be in one position for part of the exposure and suddenly shift to a slightly different position for the rest of the exposure.
What does your control software chain look like? How exactly are you running everything?
